Call the power_init() function. We appear to have forgotten about it
when deprecating lowlevel_init_subsystems(), but it didn't seem to
cause problems until we got to doing more interesting stuff recently.
There are some clean-ups to do from the original code, such as not
attempting to configure I2C from PMIC code, which we'll get around
to in follow-up patches.

Adding the 'WordBusNumber' macro to the PCI0
CRES ResourceTemplate in the Persimmon DSDT.
This sets up the bus number for the PCI0 device
and the secondary bus number in the CRS method.
This change came in response to a 'dmesg' error
which states:
'[FIRMWARE BUG]: ACPI: no secondary bus range in _CRS'
By adding the 'WordBusNumber' macro, ACPI can set
up a valid range for the PCIe downstream busses,
thereby relieving the Linux kernel from "guessing"
the valid range based off _BBN or assuming [0-0xFF].
The Linux kernel code that checks this bus range is
in `drivers/acpi/pci_root.c`. PCI busses can have
up to 256 secondary busses connected to them via
a PCI-PCI bridge. However, these busses do not
have to be sequentially numbered, so leaving out a
section of the range (eg. allowing [0-0x7F]) will
unnecessarily restrict the downstream busses.
This change will apply to other AMD mainboards and
will be in a different commit.

_RDMSR instruction loads the contents of a 64-bit model specific register (MSR)
specified in the ECX register into registers EDX:EAX.
The EDX register is loaded with the high-order 32 bits of the MSR
and the EAX register is loaded with the low-order 32 bits.
EDX:EAX = MSR[ECX]
So bit 49 will be contained in EDX register.
Buggy code instead of bit 49 (CombineCr0Cd) sets bit [49-32=17] (PfcStrideDis).
PfcStrideDis bit disables stride prefetch generation. This leads to memory
bandwidth loss.

Supermicro H8QGI board
After applying this change i observed huge memory bandwidth increase in tests
that runs on small amount of cores. But unfortunately it doesn't affect
overall bandwidth results on 4P system with 48 cores.
So i think that in this system leading limiting factor is
AMD HT-ASSIST feature (Probe filter).
But right now it is not working. System stucks in Linux boot. I have done
some experiments and figured out that stuck happens when system have cores in
compute unit (CU) other than CU with BSC (boot strap core).
CU is two cores (primary and seconary) that shares some things (L2 cache, FPU ...)
So with probe filter i can boot Linux with one (BSC)
or two (BSC + secondary core in its CU) cores.
And with this configuration i can see memory bandwidth on 1 core (or two cores)
close to original bios.

Change:
This is the initial step for moving the AMD F14 & HUDSON1,2,3
SPD-read callout out of the mainboard directories and into
the wrapper. The next step is to update the platforms to use
this routine in BiosCallouts.c and to delete the code from the
mainboard directories. The DIMM addresses should be moved into
devicetree.cb.
If there are significant differences or reasons that the mainboard
needs to override this code, it's perfectly reasonable to keep using
the version in the mainboard, but this allows us to remove duplicated
code and simplify the mainboard directories.
Notes:
This started by duplicating what was in Persimmon, and was changed to
use the devicetree.cb structures. The ASF setup was also removed from
the persimmon copy (PMIO writes to 0x28 & 0x29) as that's not needed
for the SPD access and doesn't make sense to initialize here.
Significant cleanup and magic number reduction was done as well.
It is intended that this file will not be included in ramstage as
the DIMM init is all done in romstage.
This is similar to what was done for Parmer/Thatcher in commit
7fb692bd - http://review.coreboot.org/#/c/2190/

Quoting Jens Rottmann [1]:
Nevertheless I still think this whole function is bogus for the E350M1. The
function assumes GPIO21 is wired to reset APU PCIe lane 0+1 (PCIe x8, port 4+5
as Coreboot/AGESA calls it), GPIO25 resets lane 2 (PCIe x4) and GPIO02 lane 3.
But the E350M1 has PCIe x16 i.e. probably APU lanes 0-3 bundled, completely
different layout. They could have chosen GPIO21 to force resets, or 25 - or
maybe 50 like on the Persimmon or any other they fancied or - and this is the
most probable - none at all. Having BiosGnbPcieSlotReset() toggle some GPIOs
without knowing what they do on the E350M1 (if anything at all) is nonsense.
In my opinion this whole function should just "return AGESA_UNSUPPORTED" and
good riddance.

These are essential functions for setting up the display port and
framebuffer, and also enable such things as aux channel
communications. We do some very simple initialization in romstage,
mainly set a GPIO so that the graphics is powering up, but the complex
parts are done in the ramstage. This mirrors the way in which graphics
is done in the x86 size.
I've added a first pass at a real device, and put it in the mainboard
Kconfig, hoping for corrections. Because startup is so complex,
depending on device type, I've created a 'displayport' device that
removes some of the complexity and makes the flow *much* clearer. You
can actually follow the flow by looking at the code, which is not true
on other implementations. Since display port is perhaps the main port
used on these chips, that's a reasonable compromise. All parameters of
importance are now in the device tree.

However, after some experiments in payload drivers, setting pinmux to 8 bit mode

8 bit mode by default for better performance.

the SB800 chipset is 14 MHz. sb800/bootblock.c changes this to 48 MHz,
which is the correct value for almost all SIOs. However, not for
'smscsuperio' (SMSC SCH311x), which needs the original 14 MHz and is not
configurable for other clock speeds. A wrong SIO clock supply results in
funny RS232 output (wrong bit speed) and non-working PS/2.
We could switch back to 14 MHz in the mainboard's romstage.c, but then the
clock frequency would change twice. The resulting short 48 MHz burst causes
a handful of rubbish characters on RS232 on every boot until the SIO clock
has stabilized again.
This patch skips the SB800 clock switch if the SIO Kconfig requests 14 MHz.
This does not affect any boards currently in the repository (yet).

The first reason for selecting the CPU model at compile time was a
multi-second pause if booting a single core Fusion T40R with MAX_CPUS=2.
Recent tests show the pause has disappeared, someone must have fixed it.
The second reason was me not knowing how to make a single vgabios image
work with two different PCI IDs. Many thanks to Martin Roth for educating
me! Quote:
"The way to make coreboot use the same vbios for different video device IDs
is through the map_oprom_vendev function. In family 14 it's in
northbridge/amd/agesa/family14/amdfam14_conf.c You would name your video
bios 1002,9802 in the config and all the other device/vendor IDs for the
family 14h processors will fall through the initial check for the video
bios and will get remapped to use that vbios. This only works if you're
initializing the vbios inside coreboot. I don't know if you're using
SeaBios as a payload, but if you are you can add the vbios to cbfs as
vgaroms/vbios.rom and the rom will always be initialized."
I'd like to add the vgabios is added as type 'optionrom' when Coreboot make
adds it, however to work with SeaBios it has to be added manually with
cbfstool and with type 'raw', or it will hang.

OK, this is tl;dr. But I need to write this in hopes we make
sure we don't put code like this into coreboot. Ever.
Our excuse in this case is that it was imported, not obviously wrong,
and easily changed. It made sense to get it in, make it work, then
do a cleanup pass, because changing everything up front is almost
impossible to debug.
The exynos code has bunch of base register values, e.g.
These are base addresses of things that look like a memory-mapped
struct. To get these to a pointer, they created the following macro,
which creates an inline function.
static inline unsigned int samsung_get_base_##device(void) \
{ \
return cpu_is_exynos5() ? EXYNOS5_##base : 0; \
}
And then invoke it 31 times in a .h file, e.g.:
SAMSUNG_BASE(clock, CLOCK_BASE)
to create 31 functions.
And then use it:
struct exynos5_clock *clk =
(struct exynos5_clock *)samsung_get_base_clock();
OK, what's wrong with this? It's easier to ask what's right with it. Answer: nothing.
I have a long list of what's wrong, and I may leave some things out,
but here goes:
1. the "function" can return a NULL if we're not on exynos5. Most uses of the code
don't check the return value.
2. And why would this function be running, if we're not on an exynos5? Why compile it in?
3. Note the cast everywhere a samsung_get_base_xxx is used.
The function returns an untyped variable, requiring the *user* to get two
things right: the cast, and the function invocation. One can replace that _clock(); with
_power(); in the code above, and they will be referencing the wrong registers, and
they'll never get an error!
We have a C compiler; use it to type data.
4. You're generating 31 functions using cpp each and every time the file is included.
The C compiler has to parse these each time. It's not at all like a simple cpp
macro which is only generated on use.
5. You can't tags or etags this code
6. In fact, any kind of analysis tool will be unable to do anything with this cpp magic.
That's only a partial list.
So what's the right way to do it? Just make typed constants, viz:
Or, since I expect people will want the lower case function syntax, I've left
it that way:
Now we've got something that is efficient, and we don't even need to protect with
any more.
Hence this change. We've got something that is type checked, does not require users to
cast on each use, will catch simple programming errors, can be analyzed with standard tools,
and builds faster.
So if we make a mistake:
struct exynos5_clock *clk =
samsung_get_base_adc();
We'll see it:
src/cpu/samsung/exynos5250/clock.c: In function 'get_pll_clk':
src/cpu/samsung/exynos5250/clock.c:183:3: error: initialization from incompatible pointer type [-Werror]
which we would not have seen before.
As a minor benefit, it shaves most of a second off the compilation.

If you try to reset the system with outb(3,0x92), outb(4,0xcf9) or a
triple-fault it will instead crash with a messy screen. As the more common
outb(0xFE, 0x64) doesn't work with our setup, Linux will crash whenever you
ask it to reboot. Closer inspection shows that on a warm boot of Coreboot
agesawrapper_amdinitpost() always fails with error code 7. Looks like DDR3
re-init goes wrong somehow. I tried find the reason for this but was
unable to. I am convinced this is not board specific but a bug in AGESA.
In the end I had to settle for a workaround: if amdinitpost returns 7 this
patch resets the system harder with outb(0x06, 0x0cf9), after that RAM init
will succeed. As amdinitpost is early in POST this automatic reset is
quick enough not to be noticable.
I'd perfer a real fix, but that's all I have.

Step 2: change the Persimmon code to adapt it to the new board's hardware.
The Toucan-AF is a COM Express Compact Type 6 form factor embedded board:
- AMD Fusion G-T56N (1.65 GHz dual core) or T40R (1 GHz single core) APU
- 1-4 GB DDR3 memory down
- 1x VGA, 2x DisplayPort (1 switchable to LVDS)
- AMD A55E (Hudson-E1) southbridge
- 8x USB 2.0
- 4x SATA
- HD Audio (with codec on baseboard)
- NEC uPD78F0532 microcontroller on I2C ("SEMA")
- 7x PCIe2.0 x1 (1 on PEG)
- Intel I210 GbE (on APU PCIe x1, can be disabled for additional PCIe)
- 2x SST 25VF032B (SO8, soldered) 4 MB SPI flash (BIOS and failsafe BIOS)
The Toucan-AF has no SIO on board. This patch includes basic support for a
Winbond W83627DHG (PS/2, 2x RS232), because the ADLINK ExpressBase-6 used
for evaluation happens to have one. The code may have to be adapted to the
actual baseboard of the application.

This issue has proliferated to all AMD based boards so fix it for
all of them by setting P_BLK length to 6.
The DSDT of for example AMD Parmer and AMD Thatcher also set it
to 6 everywhere so this solution is taken instead of setting the
P_BLK system I/O base to 0 for all but the first processor which
is how it is done for earlier AMD based boards.
As note having to set this manually should not be needed and
this should be autogenerated as done for most of the Intel boards
and the AMD K8 based boards (`src/cpu/amd/model_fxx/powernow_acpi.c`).

The DSDT header contains the fields OEMID and OEM Table ID. See
for example ACPI specification 4.0a [1]
5.2.11.1 Differentiated System Description Table (DSDT)
on page 135. There Table 5-16 contains the descriptions.
Field Byte Length Byte Offset Description
===================================================
OEMID 6 10 OEM ID
OEM Table ID 8 16 The manufacture model ID.
Currently in coreboot there is no common method what to put in
these fields.
Mostly Intel based boards populate it with "CORE " ore "COREv4"
and AMD based boards populate it with the board vendor and
model number, abbreviated appropriately to fit into these fields.
On most boards the proprietary vendor BIOS seems to leave these
fields – displayed with `sudo dmidecode` under System Information –
blank
To Be Filled By O.E.M.
and fill out the Base Board Information with the board vendor and
model name.
In [2] Jens Rottmann argues that the this is really just the table
ID used for naming it and that »99% of the DSDT code is not board
specific«.
Both approaches seem to have their advantages, but using the
second one, developers often seem to forget to update them (for
example AMD Thather).
The current situation is at least not optimal. and therefore at
least unify the string in the OEM Table ID. If unifying the
OEM ID is also a good idea this should be done too.
If later on it should be decided that the board vendor and model
should be used again, this should be somehow derived from
Kconfig.
The following command was used for the change [3].
$ git grep -l '\/\* TABLE ID \*\/' | xargs sed -i '/TABLE ID/s/"\([^"]*\)"/"COREBOOT"/'

Reduce unnecessary differences between AMD based boards only
using the file `platform_cfg.h` for configuration making them
a little bit easier to compare.
Inagua & co. mention the board name in several places which are really not
that board specific. Sometimes people even forget to change it:
Union Station’s platform_cfg.h starts with "#ifndef _PERSIMMON_CFG_H_".
Funny. Change that to "_PLATFORM_CFG_H_" everywhere.
The following command was used.
$ find . -name platform_cfg.h | xargs sed -i '/_CFG_H_/s/_.*_/_PLATFORM_CFG_H_/'
More boards seem to use that kind of naming (`git grep _CFG_H_`)
but it is not certain that this will not break anything as for
example the board AMD Dinar also has header files for
configuration stuff for the north- and southbridge.
$ git grep _CFG_H_

Payloads, by design, can return. There's lots of mechanism in the payload code
to support it, and the chooser payload relies on it. Hence, we should not mark
the function call in exit_stage as noreturn.
Not all ARM have unified caches, and it's not always easy to tell what
to do. So we are very paranoid. Before we call between stages, we
should carefully flush the dcache to memory and invalidate the icache.
This may be more than is necessary on all architectures but it
doesn't really hurt for the most part.
So compile cache management code into all stages, and call the
flush dcache/invalidate icache from all stages.

passing argument 3 of 'mptable_write_buses' from incompatible pointer type [enabled by default]
mptable_write_buses is expecting a pointer to an int, so I changed the
U8 isa_bus to an int to match. A U8 doesn't make sense if the value could
be greater than 255 - certainly unlikely, but possible since the value
of isa_bus gets set to the maximum PCI bus number + 1.

The 8 bit value 0x2A (binary 00 10 10 10), was being used incorrectly
– I believe the original intent of this value was to enable the SDIN
pins 0, 1, & 2. Because it was getting truncated as it was put into
AzaliaSdin0, this wasn't happening and only SDIN0 was being enabled.
I am leaving only SDIN0 enabled at this point to as not change the

Inagua can use GPIOs 178,179 to switch VMEM to 1.5, 1.35 or 1.25 V,
which it does according to data read from the SO-DIMM's SPD EEPROM.
On Persimmon (according to DB-FT1 rev. D schematics) both GPIOs are
unconnected, there is no way to change the 1.5 V DDR3 voltage (save
unsoldering a resistor). The whole code copied over from Inagua is
useless.
Removed the code, instead a comment hints at Inagua, for people who do designs
based on Persimmon but do have a way to change VMEM.
The line ...->DDR3Voltage = VOLT1_5; is supposed to make the AGESA DDR3 code
select the RAM timings for the actually supplied voltage instead of the
hoped-for but unavailable lower voltage. I have no idea how to test this, but
in any case it can't hurt.

Comparing Persimmon and Inagua schematics and Coreboot code show the PCIe reset
code has been blindly copied even though it doesn't suit the Persimmon at all.
The Inagua can employ GPIOs 21, 25, 02 to manually reset devices on APU PCIe
lanes 0/1, 2, 3 respectively. (Appearently the motivation for this is to revive
buggy PCIe gen1 devices which got confused by PCIe gen2 signal training.)
However the Persimmon not only doesn't support this, it even needs these 3 pins
for the PCI interface! Instead it uses GPIO50 to reset devices on lanes 0-2 all
at once. Lane 3 is unconnected anyway.
This patch adapts the Persimmon mainboard code according to the DB-FT1 rev. D
schematics.

- Add a STACK_SIZE Kconfig variable. Earlier on it was evaluated to 0.
- Assign _stack and _estack using CPU-specific Kconfig variables since
it may reside elsewhere in memory (not necessarily DRAM).
- Make the existing IRAM stack variables more useful in this context.

mmu_setup() was originally written in U-Boot to utilize board-specific

parameters so that board-specific info can be passed in via mainboard
code. Let's start using it that way.

MMCONF space is defined by two config parameters:
MMCONF_BASE_ADDRESS (0xF800 0000)
MMCONF_BUS_NUMBER (64)
Coreboot allocates 1MB per bus, so MMCONF limit should be:
0xF800 0000 + 64*(0x0010 0000) - 1 = 0xFBFF FFFF
Current code does not have (-1) component, this makes MMCONF limit
equal 0xFC00 FFFF. Not 0xFC00 0000, because according to BKDG
lower two bytes of MMIO limit always equal 0xFFFF:
MMIOLimit = {MMIOLimitRegister[47:16], FFFFh}.
Add (-1) to correct this issue.
No functionality change has been experienced. The five times

remains.

RAMBASE and RAMTOP are leftovers from the x86 port and do not apply
the same way on ARM platforms. On x86 they refer to the low memory
region where coreboot tables reside.
However on ARM we don't have such a region which is architecturally
defined. So instead we'll use the CPU-defined DRAM base address and
the mainboard-defined DRAM size.
This also has the pleasant side-effect of fixing the coreboot tables
to not clobber ramstage code...

Early console should always be allowed to be turned on / off (for generating
production and debug versions), and should not be enforced by "select" Kconfig
rule.
A new "DEFAULT_EARLY_CONSOLE" is introduced for devices to select if they
prefer early console output by default.
Verified Kconfig value on qemu/x86 (default y by CACHE_AS_RAM), snow/x86

For Exynos platforms, the UART component on pinmux must be first selected and
configured. This should be done as part of UART console initialization.
Note, that the current implementation hard-codes the device index as UART3,
while the base port can be assigned to different device in Kconfig. This will be
fixed later.

The console drivers (especially serial drivers) in Kconfig were named in
different styles. This change will rename configuration names to a better naming
style.
- EARLY_CONSOLE:
Enable output in pre-ram stage. (Renamed from EARLY_SERIAL_CONSOLE
because it also supports non-serial)
- CONSOLE_SERIAL:
Enable serial output console, from one of the serial drivers. (Renamed
from SERIAL_CONSOLE because other non-serial drivers are named as
CONSOLE_XXX like CONSOLE_CBMEM)
- CONSOLE_SERIAL_UART:
Device-specific UART driver. (Renamed from
CONSOLE_SERIAL_NONSTANDARD_MEM because it may be not memory-mapped)
- HAVE_UART_SPECIAL:
A dependency for CONSOLE_SERIAL_UART.
Verified to boot on x86/qemu and armv7/snow, and still seeing console

The common part of the bootblock resets the nvram data if it's found
to be invalid. Since that code is compiled with romcc in i386 mode,
there's a shortage on registers.
Try to reduce the strain by doing things smarter: cmos_write_inner
is the same as cmos_write, just that it doesn't check if the RTC is
disabled. Since we just disabled it before, we can assume that it is so.

This patch moves ARM core and DRAM timing functions around to simplify
the dependencies for system_clock_init().
The original code was architected such that the system_clock_init()
function called other functions to obtain core and memory timings.
Due to the way memory timing information must be obtained on Snow,
which entails decoding platform-specific board straps, the bottom-
up approach resulted in having the low-level clock init code
implicitly depend on board and vendor-specific info:
main()
->system_clock_init()
-> get_arm_ratios()
-> CPU-specific code
-> clock_get_mem_timings()
-> board_get_revision()
-> read GPIOs (3-state logic)
-> Decode GPIOs in a vendor-specific manner
-> Choose memory timings from module-specific look-up table
...then proceed to init clocks
...come back to main()
The new approach gathers all board and vendor-specific info in a
more appropriate location and passes it into system_clock_init():
main()
-> get_arm_ratios()
-> CPU-specific code
-> get_mem_timings()
-> board_get_config()
-> read GPIOs (3-state logic)
-> Decode GPIOs in a vendor-specific manner
-> Choose memory timings from module-specific look-up table
-> system_clock_init()
...back to main()

Usage Changes: To support platforms with different memory layout, "create" takes
two extra optional parameters:
"-b": base address (or offset) for bootblock. When omitted, put bootblock in
end of ROM (x86 style).
"-H": header offset. When omitted, put header right before bootblock,
and update a top-aligned virtual address reference in end of ROM.
Example: (can be found in ARM MAkefile):
cbfstool coreboot.rom create -m armv7 -s 4096K -B bootblock.bin \
-a 64 -b 0x0000 -H 0x2040 -o 0x5000

Snow's AP, EC, PMU, and smarty battery share a bus. Both the AP and
EC can act as a master, so to avoid conflicts an arbitration
mechanism consisting of two GPIOs is used.
By default, the AP "owns" the bus unless it is off (in which case
the EC doesn't monitor the arbitration pins). This means the boot
firmware does not need to worry about these lines. The payload may
if it needs to communicate with the EC, though.
In any case, board-specific bus arbitration logic does not belong
in a low-level driver that is supposed to be generic for an entire
CPU family. If the payload needs to talk to the EC, we'll deal with
it there.

For ARM platform, the bootblock may need more C source files to initialize
UART / SPI for loading romstage. To preventing making complex and implicit
dependency by using #include inside bootblock.c, we should add a new build class
"bootblock".
Also #ifdef __BOOT_BLOCK__ can be used to detect if the source is being compiled
for boot block.
For x86, the bootblock is limited to fewer assembly files so it's not using this
class. (Some files shared by x86 and arm in top level or lib are also changed
but nothing should be changed in x86 build process.)

Since we only need to print in bases 8, 10, and 16, do a minor
restructuring of the code so that we call do_div with constants.
If you need base 2, print in base 16 and do it in your head. :-)
This fixes an ongoing problem with ARM, will not harm X86, and will

Summary:
Isolate CBFS underlying I/O to board/arch-specific implementations as
"media stream", to allow loading and booting romstage on non-x86.
CBFS functions now all take a new "media source" parameter; use
CBFS_DEFAULT_MEDIA if you simply want to load from main firmware.
API Changes:
cbfs_find => cbfs_get_file.
cbfs_find_file => cbfs_get_file_content.
cbfs_get_file => cbfs_get_file_content with correct type.
CBFS used to work only on memory-mapped ROM (all x86). For platforms like ARM,
the ROM may come from USB, UART, or SPI -- any serial devices and not available
for memory mapping.
To support these devices (and allowing CBFS to read from multiple source
at the same time), CBFS operations are now virtual-ized into "cbfs_media". To
simplify porting existing code, every media source must support both "reading
into pre-allocated memory (read)" and "read and return an allocated buffer
(map)". For devices without native memory-mapped ROM, "cbfs_simple_buffer*"
provides simple memory mapping simulation.
Every CBFS function now takes a cbfs_media* as parameter. CBFS_DEFAULT_MEDIA
is defined for CBFS functions to automatically initialize a per-board default
media (CBFS will internally calls init_default_cbfs_media). Also revised CBFS
function names relying on memory mapped backend (ex, "cbfs_find" => actually
loads files). Now we only have two getters:
struct cbfs_file *entry = cbfs_get_file(media, name);
void *data = cbfs_get_file_content(CBFS_DEFAULT_MEDIA, name, type);
Test results:
- Verified to work on x86/qemu.
- Compiles on ARM, and follow up commit will provide working SPI driver.

This patch adds some DEBUG_SPEW prints to the DDR3 code. I am doing this
as its own CL because we may find we want to revert it. That's unlikely
but it is not impossible if we skew the timing in some way.

The timing array is crucial to proper operation of DRAM.
Getting a valid pointer to it is hence very important. Unfortunately,
the constants chosen for the vendor were '1', and '2', (this in a
32-bit word) which in a debug print makes it almost impossible to tell
if you've got a misaligned pointer. Note: coreboot people did not
choose them :-)
So, give them values which are extremely unlikely to occur elsewhere
in the array (or in memory, for that matter).
Given the frequency with which this check occurs, i.e. once, I would
much prefer strings but I expect I'd get shouted down on that
one. Constants in this case are an almost useless optimization but
we'll go with them for now. Note no space is saved by not using
strings: there's an entire function somewhere devoted to mapping the
enum to a string!
Debug prints of pointers to structs in this array are now far more
useful than they were.
See snarky comment in the code (left there to make sure nobody gets
tempted to get fancy again). Comment now less snarky.
This is tested on google snow to the point that the DRAM works.

Currently "cbfstool locate" outputs a hex number without "0x" prefix.
This makes extra step (prefix 0x, and then generate another temp file) in build
process, and may be a problem when we want to allow changing its output format
(ex, using decimal). Adding the "0x" in cbfstool itself should be better.

There is a disconnect between how the devicetree should be configured
if there are multiple HT links on the CPU and how it's configured if
there's only one HT link. These platforms were set up as if they
had multiple HT links, which was causing duplicate instances of
devices in the device list.

This patch does a few things to get us into romstage:
- Add romstage as a stage (a later patch adds it as a binary, which
is probably wrong). The Makefile magic is complex enough that we
let it build the XIP file for now, but we no longer use it.
- Replace findstage with loadstage. Loadstage will find a stage,
load the code to memory, and zero the remaining part of memory.
Now we can link the romstage to go anywhere!
- Eliminate magic offsets from code/ldscripts and centralize Kconfig
variables in src/cpu/samsung/exynos5250/Kconfig.
- Tidy up code and serial output

This adds a wrapper around main() in romstage which is compiled using
-marm. This assumes that the bootblock branches to romstage in ARM
mode.
The long-term idea is to enforce ABI compatibility when handing off to
the next stage by using shims which are which are compiled in a pre-
determiend manner and leave the main portions of each stage up to
whatever the compiler wants. So it will eventually look like this:
1. bootblock_main (ARM/Thumb)
2. bootblock_exit (ARM)
3. romstage_entry (ARM)
4. romstage_main (ARM/Thumb)

This replaces hard-coded bootblock offsets using the new scheme.
The assembler will place the initial branch instruction after BL1,
skip 2 aligned chunks, and place the remaining bootblock code after.
It will also leave an anchor string, currently 0xdeadbeef which
cbfstool will find. Once found, cbfstool will place the master CBFS
header at the next aligned offset.
Here is how it looks:
0x0000 |--------------|
| BL1 |
0x2000 |--------------|
| branch |
0x2000 + align |--------------|
| CBFS header |
0x2000 + align * 2 |--------------|

In order to provide some insight on what code is executed during
coreboot's run time and how well our test scenarios work, this
adds code coverage support to coreboot's ram stage. This should
be easily adaptable for payloads, and maybe even romstage.
See http://gcc.gnu.org/onlinedocs/gcc/Gcov.html for
more information.
To instrument coreboot, select CONFIG_COVERAGE ("Code coverage
support") in Kconfig, and recompile coreboot. coreboot will then
store its code coverage information into CBMEM, if possible.
Then, run "cbmem -CV" as root on the target system running the
instrumented coreboot binary. This will create a whole bunch of
.gcda files that contain coverage information. Tar them up, copy
them to your build system machine, and untar them. Then you can
use your favorite coverage utility (gcov, lcov, ...) to visualize
code coverage.
For a sneak peak of what will expect you, please take a look
at http://www.coreboot.org/~stepan/coreboot-coverage/

Since coreboot is compiled into 32bit code, and userspace
might be 32 or 64bit, putting a pointer into the coreboot

big enough for a pointer, even if we decide to move to a 64bit
coreboot at some point.

This patch makes pre-RAM serial init more generic, particularly for
platforms which do not necessarily need cache-as-RAM in order to use
the serial console and do not have a standard 8250 serial port.
This adds a Kconfig variable to set romstage-* for very early serial
console init. The current method assumes that cache-as-RAM should
enable this, so to maintain compatibility selecting CACHE_AS_RAM will
also select EARLY_SERIAL_CONSOLE.
The UART code structure needs some rework, but the use of ROMCC,
romstage, and then ramstage makes things complex.
uart.h now includes all .h files for all uarts. All 2 of them.
This is actually a simplifying change.

are -march=armv7-a and -mthumb (to allow 16-bit Thumb instructions).
I removed the hard float support because it got errors and
coreboot should never use floats anyway. We're still having trouble
with enums but I want to see how far it gets with this patch.
Also, put the flags in a form that makes diffs easier to read. It's
almost impossible otherwise.
Finally, move some flags to the architecture Makefile, and
rely on the fact that some are set for all architectures.

The AMD Inagua, Parmer and Thatcher boards were already adapted but
the define was left in. So just remove it for those.

There was already a special case for the SPI base address in
lpc_set_resources for southbridge/amd/cimx/sb800 and
southbridge/amd/agesa/hudson, but it needed to be modified
to keep from killing the IMC rom during initialization. As
soon as the BAR is disabled by setting the new base address,
the IMC dies. The fix is to make sure it's still enabled
when setting the new base address instead of setting the new
address then re-enabling it.
Change the name SPIROM_BASE_ADDRESS to SPIROM_BASE_ADDRESS_REGISTER
to more accurately describe what we're using.

The SB800 and Hudson now support adding the IMC ROM which runs from the same
chip as coreboot. When the IMC is running, write or erase commands sent to
the spi bus will fail, and the IMC will die. To fix this, we send a request
to the IMC to stop fetching from the SPI rom while we write to it. This
process (in one form or another) is required for writes to the SPI bus while
the IMC is running.
Because the IMC can take up to 500ms to respond every time we claim the
bus, this patch tries to keep the number of times we need to do that to a
minimum. We only need to claim the bus on writes, and using a counter for
the semaphore allows us to call in once to claim the bus at the beginning
of a number of transactions and it will stay claimed until we release it
at the end of the transactions.
Claim() - takes up to 500ms hit
claim() - no delay
erase()
release()
claim() - no delay
write()
release()
Release()

As we move to supporting other systems we need to get rid of assembly

one (tested for all 32-bit signed integers :-) and takes about 10 ns

This gets rid of the somewhat unstructured placement of AMD's
sysinfo structure in CAR.
We used to carve out some CAR space using a Kconfig variable,
and then put sysinfo there manually (by "virtue" of pointer magic).
Now it's a variable with the CAR_GLOBAL qualifier, and build
system magic.
For this, the following steps were done (but must happen together
since the intermediates won't build):
- Add new CAR_GLOBAL sysinfo_car
- point all sysinfo pointers to sysinfo_car instead of GLOBAL_VAR
- remove DCACHE_RAM_GLOBAL_VAR_SIZE
- from CAR setup (no need to reserve the space)
- commented out code (that was commented out for years)
- only copy sizeof(sysinfo) into RAM after ram init, where
before it copied the whole GLOBAL_VAR area.
- from Kconfig

is that POST codes should be written to an IO port (e.g. LPC) if POST

be written to the serial console without being written to an IO port.
This enables POST codes by default using "default y" to avoid

The SMM GNVS pointer is normally updated only when the
ACPI tables are created, which does not happen in the
resume path.
In order to restore this pointer it needs to be available
at resume time. The method used to locate it at creation
time cannot be used again as that magic signature is
overwritten with the address itself. So a new CBMEM ID
is added to store the 32bit address so it can be found
again easily.
A new function is defined to save this pointer in CBMEM
which needs to be called when the ACPI tables are created
in each mainboard when write_acpi_tables() is called.
The cpu_index variable had to be renamed due to a conflict
when cpu/cpu.h is added for the smm_setup_structures()

This prepares the way for vboot to inform coreboot when it needs the VGA

By the time we get to U-Boot, it's too late, so we need two extra bits - one
for vboot to tell coreboot to load the Option ROM and another for coreboot
to let vboot know it's been done.
This change sets up the communication, but doesn't act on it just yet.
Even with this CL we always load the VGA Option ROM, so there's nothing to
test. There should be no user-visible change.

The problem is solved by moving the logic to keep a few timestamps
around into the timestamp code. This also gets rid of a lot of ugly

This change allows us to figure out how much of the AP stacks we are
using, as well as to catch any case of an AP overrunning its stack.
Also, the stack is poisoned, which is a good way to catch programming
errors -- code should never count on auto variables being zerod.
The stack bases are recorded in a new array, stacks. At the end,
when all APs are initialized, the stacks are walked and the
lowest level of the stack that is reached is printed.
Build and boot and look for output like this:
CPU1: stack allocated from 00148000 to 00148ff4:\
lowest stack address was 00148c4c
CPU2: stack allocated from 00147000 to 00147ff4:\
lowest stack address was 00147c4c
CPU3: stack allocated from 00146000 to 00146ff4:\
lowest stack address was 00146c4c
Note that we used only about 1K of stack, even though in this
case we allocated 4K (and in the main branch, we allocate 32K!)

This is a basic romstage driver that can be used for the
MRC cache code on systems where we do not have the MRC cache
stored in a flash region that is memory mapped.
It uses the hardware sequencing interface to avoid having
to know anything about the flash chip itself.

that attempted to read the MRC cache at offset 0x3e0000.

If the event log is stored in flash that is not memory
mapped then it must use the SPI controller to read from
the flash device instead of relying on memory accesses.
In addition a new CBMEM ID is added to keep an resident
copy of the ELOG around if needed. The use of CBMEM for
this is guarded by a new CONFIG_ELOG_CBMEM config option.
This CBMEM buffer is created and filled late in the process
when the SMBIOS table is being created because CBMEM is
not functional when ELOG is first initialized.
The downside to using CBMEM is that events added via the
SMI handler at runtime are not reflected in the CBMEM copy
because I don't want to let the SMM handler write to memory
outside the TSEG region.
In reality the only time we add runtime events is at kernel
shutdown so the impact is limited.
Test:
1) Test with CONFIG_ELOG_CBMEM enabled to ensure the event
log is operational and SMBIOS points to address in CBMEM.
The test should involve at least on reboot to ensure that the
kernel is able to write events as well.

At least when CONFIG_CHROMEOS is turned on, it's possible for
CONFIG_FRAMEBUFFER_KEEP_VESA_MODE to be set but for there not to be any valid
information to put into the framebuffer coreboot table. That means that what's
put in there is junk, probably all zeroes from the uninitialized global
variable the mode information is stored in (mode_info).
When a payload uses libpayload and turns on the coreboot framebuffer console,
that console will attempt to scroll at some point and decrease the cursor's y
coordinate until it is less than the number of rows claimed by the console.
The number of rows is computed by taking the vertical resolution of the
framebuffer and dividing it by the height of the font. Because the mode
information was all zeroes, the coreboot table info is all zeroes, and that
means that the number of rows the console claims is zero. You can't get the
unsigned y coordinate of the cursor to be less than zero, so libpayload gets
stuck in an infinite loop.
The solution this change implements is to add a new function,
vbe_mode_info_valid, which simply returns whether or not mode_info has anything
in it. If not, the framebuffer coreboot table is not created, and libpayload
doesn't get stuck.

The linux kernel relies on the RTC reporting pending interrupts if
the RTC alarm was used to wake the system. If we clear these flags
here then the rtc-cmos driver in the kernel will think that no
interrupts are pending and will not re-start the timerqueue to
handle the alarm timerqueue node.
This flag doesn't exist in SMM but the rtc code is compiled there.
Since rtc_init() is not called by SMM it is guarded with an ifdef.
I performed several thousand suspend/resume cycles without seeing
an issue where hwclock was unable to read from /dev/rtc. There
still is a potential kernel issue where the timerqueue can stall
but this makes that much less likely to happen on resume.

Until now, the MRC cache position and size was hard coded in Kconfig.
However, on ChromeOS devices, it should be determined by reading the
FMAP.
This patch provides a minimalistic FMAP parser (libflashmap was too
complex and OS centered) to allow reading the in-ROM flash map and
look for sections.
This will also be needed on some partner devices where coreboot will
have to find the VPD in order to set up the device's mac address
correctly.
The MRC cache implementation demonstrates how to use the FMAP parser.

PCIE devices are detected and initialized by the AMD PCIe init functions,
which is in cimx rd890. The parameters are read from devicetree.cb before PCIe init.
Now, all bridges and devices are trained on the device 0.0 enable.
After PCIe init, the PCIe ports with devices are on and the PCIe ports
without devices are off. so resources may be allocated correctly
during the rest of the PCI scan.
But if the devicetree was being used to enable/disable devices after initialization,
the problems would arise. Take a look at the serial log:
do_pci_scan_bridge for PCI: 00:02.0
PCI: pci_scan_bus for bus 01
PCI: pci_scan_bus returning with max=001
do_pci_scan_bridge returns max 1
do_pci_scan_bridge for PCI: 00:03.0
PCI: pci_scan_bus for bus 02
PCI: pci_scan_bus returning with max=002
do_pci_scan_bridge returns max 2
do_pci_scan_bridge for PCI: 00:04.0
PCI: pci_scan_bus for bus 03
PCI: pci_scan_bus returning with max=003
do_pci_scan_bridge returns max 3
PCI bridge 02.0, 03.0 and 04.0 are not inserted devices, but these bridges
are still scanned. This is not correct.

There are four mainboards using agesa family15 code:

All of these boards' PCI domain starts from 0x18.0. Take h8scm as
an example, PCI devices from 0.0 to 0x14.5 is under 0x18.0.
Now, the PCI domain's scan bus function stats from 0.0. This would
result to the PCI devices be scanned twice. Because when the function
run to device 18.0, it would scan from 0.0 again.
This issue would result to 2 problems:
1) PCI device may be assigned two different PCI address.
If this happenned on VGA device, coreboot maybe not load
vga bios correctly.
2) coreboot initializes rd890's IO APIC twice.
So this patch scans from 0x18.0 and could resolve the problems above.

pirq_routing_irqs assumed that only four links are available for PIRQ
routing, INTA to INTD. Some chipsets provide more, up to INTH.
When pirq_routing_irqs found a link number greater than 4 in the pirq table,
it would not assign that IRQ. This is a shame, as it limits the flexibility
of routing IRQs.
Make the maximum number of links a Kconfig variable, and modify the code to
respect it. This works beatifully on the VX900, which provides 8 routable
interrupts.
While we're at it, also refactor pirq_routing_irqs, and add some much

Rename pirq_routing_irqs to pirq_route_irqs to demistify the role of this

Add code to do the following for the VIA Nano CPUs
- Update microcode
- Set maximum frequency
- Initialize power states
- Set up cache
Attempting to change the voltage or frequency of the CPU without
applying the microcode update will hang the CPU, so we only do
transitions if we can verify the microcode has been updated.
The microcode is updated directly from CBFS. No microcode is
included in ramstage. The microcode is not included in this
commit.
To get the microcode, run bios_extract on the manufacturer supplied
BIOS, and look for the file marked "P6 Microcode". Include this
file in CBFS.
You can have the build system include this file automatically by
selecting Expert Mode, then look under
'Chipset' -> 'Include CPU microcode in CBFS' ->
Include external microcode file (check)
'Path and filename of CPU microcode' should contain the location of
the microcode file previously extracted.

This patch aims to improve the microcode in CBFS handling that was
brought by the last patches from Stefan and the Chromium team.
Choices in Kconfig
- 1) Generate microcode from tree (default)
- 2) Include external microcode file
- 3) Do not put microcode in CBFS
The idea is to give the user full control over including non-free
blobs in the final ROM image.
MICROCODE_INCLUDE_PATH Kconfig variable is eliminated. Microcode
is handled by a special class, cpu_microcode, as such:
cpu_microcode-y += microcode_file.c
MICROCODE_IN_CBFS should, in the future, be eliminated. Right now it is
needed by intel microcode updating. Once all intel cpus are converted to
cbfs updating, this variable can go away.
These files are then compiled and assembled into a binary CBFS file.
The advantage of doing it this way versus the current method is that
1) The rule is CPU-agnostic
2) Gives user more control over if and how to include microcode blobs
3) The rules for building the microcode binary are kept in
src/cpu/Makefile.inc, and thus would not clobber the other makefiles,
which are already overloaded and very difficult to navigate.

The CPU can arbitrarily reorder calls to rdtsc, significantly
reducing the precision of timing using the CPUs time stamp counter.
Unfortunately the method of synchronizing rdtsc is different
on AMD and Intel CPUs. There is a generic method, using the cpuid
instruction, but that uses up a lot of registers, and is very slow.
Hence, use the correct lfence/mfence instructions (for CPUs that
we know support it)

Some mainboards have really nice capabilities for posting, beyond
simple POST cards. Further, some can not use a POST card. This
change defines a weak symbol (mainboard_post) that can be overridden
by a real mainboard_post function.
If, for example, you'd like to do something fancy before the payload starts,
you can add this to mainboard.c:
void mainboard_post(u8 value)
{
switch(value){
case POST_TIME_TO_PARTY: some_fancy_lights();
break;
}
}
Maybe the post function should be an entry in the device. We're beginning to over-use
weak symbols.

We thought about two ways to do this change. The way we decided to try
was to
1. drop all ops from devices in romstage
2. constify all devices in romstage (make them read-only) so we can
compile static.c into romstage
3. the device tree "devices" can be used to read configuration from
the device tree (and nothing else, really)
4. the device tree devices are accessed through struct device * in
romstage only. device_t stays the typedef to int in romstage
5. Use the same static.c file in ramstage and romstage
We declare structs as follows:
ROMSTAGE_CONST struct bus dev_root_links[];
ROMSTAGE_CONST is const in romstage and empty in ramstage; This
forces all of the device tree into the text area.
So a struct looks like this:
static ROMSTAGE_CONST struct device _dev21 = {
#ifndef __PRE_RAM__
.ops = 0,
#endif
.bus = &_dev7_links[0],
.path = {.type=DEVICE_PATH_PCI,{.pci={ .devfn = PCI_DEVFN(0x1c,3)}}},
.enabled = 0,
.on_mainboard = 1,
.subsystem_vendor = 0x1ae0,
.subsystem_device = 0xc000,
.link_list = NULL,
.sibling = &_dev22,
#ifndef __PRE_RAM__
.chip_ops = &southbridge_intel_bd82x6x_ops,
#endif
.chip_info = &southbridge_intel_bd82x6x_info_10,
.next=&_dev22
};

With SandyBridge northbridge code, uma_memory_size was reset to
zero before variable MTRRs were set. This means MTRR setup routine
did not previously create a un-cacheable hole for uma.
Keep the behaviour that way, mmio_resource() has a prerequisuite that
the new region does not overlap with any cacheable ram_resource().
The result is not optimal setup in the number of used MTRRs, but
continue with this approach until MTRR algorithm is improved.

Commit 2d42b34003 changed the
variable MTRR setup and removed compensation of uma_memory_size in
the cacheable memory resources.
Since the cacheable region size was no longer divisible by a large
power of 2, like 256 MB, this caused excessive use of MTRRs.
As first symptoms, slow boot with grub and poor user response.
As a solution, register the actual top of low ram with ram_resource(),
and do not subtract the UMA/TSEG regions from it.
TSEG may require further work as the original did not appear exactly
right to begin with. To have UMA as un-cacheable, use uma_resource().

In order to support the GSMI interface the SMI handler needs
to find and use the state save area from the same CPU that
initiated the SMI. In this case it is a synchronous SMI
resulting form an IO write to port 0xB2.
To find the right CPU state save area iterate over the region
until the "IO Misc Info" field reports the expected value and
then proceed to use that state save area.
This is needed because the coreboot SMI handler only executes on
one core, and that core is non-deterministic. It is likely that
the core executing the C SMM handler is not the same one that
actually did the IO write to 0xB2 and generated the SMI.
The GSMI parameter buffer is passed as a pointer to EBX in the
tate save area, and the GSMI command is extracted from EAX before
it is used as the return value.
This interface is tested by enabling CONFIG_GOOGLE_GSMI in the
kernel and generating events and verifying that they end up
in the event log.

The linux kernel contains an SMI driver that was written by
me (Duncan) and upstreamed a couple years ago called GSMI.
This driver will format a parameter buffer and pass pointers
to this parameter buffer to the SMI handler. It uses this to
generate events for kernel shutdown reasons: Clean, Panic, Oops,
etc.
This function expects to be passed pointers into the SMM state
save area that correspond to the prameter buffer and the return
code, which are typically EAX and EBX.
The format of the parameter buffer is defined in the kernel
driver so we implement the same interface here in order to be
compatible.
GSMI_CMD_HANDSHAKE: this is an early call that it does to try
and detect what kind of BIOS is running.
GSMI_CMD_SET_EVENT_LOG: this contains a parameter buffer that
has event type and data. The kernel-specific events are
translated here and raw events are passed through as well which
allows any run-time event to be added for testing.
GSMI_CMD_CLEAR_EVENT_LOG: this command clears the event log.
First the gsmi driver must be enabled in the kernel with
CONFIG_GOOGLE_GSMI and then events can be added via sysfs
and events are automatically generated for various kernel
shutdown reasons.
These can be seen in the event log as the 'Kernel Event' type:

coreboot used to pass some information to u-boot in the coreboot table
and other information in a modified flat device tree. Since the FDT code
was never upstreamed and removed from our tree, u-boot was changed to
get the information it needs from the coreboot table alone. However,
in the process of this change only the vboot shared data structure was
passed on by coreboot, so when u-boot tried to update the ChromeOS
specific ACPI entries, it would accidently overwrite the vboot data.
This patch passes on the ChromeOS specific ACPI data structure instead
of the vboot shared data. Another change to u-boot will teach it how
to get to the vboot shared data from there.

CPUs with configurable TDP will run the TSC at the max non-turbo
ratio for the maximum TDP value, which can cause issues if another
TDP is desired. To deal with this we set the flex ratio to the
nominal TDP ratio early in the boot and then configure the Soft
Reset Data registers so the PCH can tell the CPU what frequency
to run at after a reset.
This is done very early in the bootblock because it is necessary
to reset the system after setting a flex ratio.
The end result is that the TSC will now increment at the max
non-turbo frequency for the nominal TDP.
On some system with 1.8GHz CPU ensure that the kernel
detects the CPU speed as ~1800mhz rather than ~2300mhz:

This is based around the SMBIOS event log specification but
expanded with OEM event types to support more specific and
relevant system events.
It requires flash storage and a minimum 4K block (or flash block
size) that should be allocated in the FMAP.
A copy of the event log is maintained in memory for convenience
and speed and the in-memory copy is written to flash at specific
points.
The log is automatically shunk when it reaches a configurable
full threshold in order to not get stuck with a full log that
needs OS help to clear.
ELOG implements the specification published here:
http://code.google.com/p/firmware-event-log/wiki/FirmwareEventLogDesign
And is similar to what we use in other firmware at Google.
This implementation does not support double-buffered flash
regions. This is done because speed is valued over the log
reliability and it keeps the code simpler for the first version.
This is a large commit and by itself it just provides a new
driver that is made available to coreboot. Without additional

For now this change just forces everything to use the Nominal TDP

ratio based on the Nominal ratio if available.
- Set the turbo activation ratio to the Nominal max ratio.
- Mirror the power level settings in new MCHBAR register after

- Set the current ratio to Nominal ratio at boot.
1) Verify that P-state table is generated properly with

especially now that the lzma decoder doesn't use a giant 16K on-stack

Break the stack checking out into a separate function, which
we will later use for the APs.
CPU0: stack from 00180000 to 00188000:Lowest stack address 00187ad8
To test failure, change the DEADBEEF stack poison value in c_start.S

Stack overrun on BSP.Increase stack from current 32768 bytes
CPU0: stack from 00180000 to 00188000:Lowest stack address 00180000
Separate the act of loading from the act of starting the payload. This
allows us better error management and reporting of stack use. Now we
see:

When microcode storage in CBFS is enabled, the make system is supposed
to generate the microcode blob and place it into the generated ROM
image as a CBFS component.
The microcode source representation does not change: it is still an
array of 32 bit constants. This new addition compiles the array into a
separate object file and then strips all sections but data.
The raw data section is then included into CBFS as a file named
'microcode_blob.bin' of type 0x53, which is assigned to microcode
storage.

After the switch from romstage to ramstage the smb base address

stored in bar0 of the ISA bridge. It could also be read via msr,
but via PCI it is simpler. I used the following patch as

There are several reasons for this:
1. It's a core setting, not a platform setting, which is bizarre. But,
we disable vmx via an SMI, and that only happens on core 0.
Hence, the code did not correctly make the same settings on all cores-
one had them disabled, the others were in an unknown state.
When (e.g.) kvm started on a vmx-enabled core, then moved to a
vmx-disabled core, the processor would reset *very* quickly.
Changing this would be messy.
2. On the CPU on link, there is something about trying to set the lock
bit that is getting a GPF.
3. It's the wrong place and time to set it. Once controlled, they can't
be changed in the kernel. The kernel is what should control this
feature, not the BIOS, as we have learned time and time again. If
somebody is in as root and can start a VM, you have a lot more to
worry about than someone starting a guest virtual machine.
