Now that we use the microcode updates in the blobs repository, remove
them from the main repo. Since the microcode updates are blobs, it
makes more sense to ship them in the blobs repo rather than the main
one.
The update-microcodes.sh script is also deleted, as a more current
version resides in 3rdparty.

Now that microcode has been added to blobs, use that one instead of
the one included in the tree. Microcode from the tree will be
removed in a subsequent patch. Since the microcode updates are blobs,
they belong in the blobs repository.
This change may introduce a build failure if the "Generate from tree"
microcode option is selected, but the blobs repository is not
enabled. We have to live with this for now, until microcode is moved
to blobs for all CPUs, at which point we may adjust Kconfig
accordingly.
Leave the FSP cpu alone for now, as that will need approval from
SAGE.

This patch adds I2C emulation in software through raw toggling of the
SDA/SCL lines. Platforms need to provide bindings to toggle their
respective I2C busses for this to work (e.g. by pinmuxing them as GPIOs,
currently only enabled for Tegra).
This is mostly useful as a debugging feature, to drive unusual states on
a bus and closely monitor the device output without the need of a bus
analyzer. It provides a few functions to "wedge" an I2C bus by aborting
a transaction at certain points, which can be used to test if a system
can correctly recover from an ill-timed reboot. However, it can also
dynamically replace the existing I2C transfer functions and drive
some/all I2C transfers on the system, which might be useful if a driver
for the actual I2C controller hardware is not (yet) available.
Based on original code by Doug Anderson <dianders@chromium.org> and
Hung-ying Tyan <tyanh@chromium.org> for the ChromeOS embedded
controller project.

The following patches had to be squashed
to properly build all the different ARM boards.
ipq8064: storm: re-arrange bootblock initialization
The recent addition of the storm bootblock initialization broke
compilation of Exynos platforms. The SOC specific code needs to be
kept in the respective source files, not in the common CPU code.
As of now coreboot does not provide a separate SOC initialization API.
In general it makes sense to invoke SOC initialization from the board
initialization code, as the board knows what SOC it is running on.
Presently all what's need initialization on 8064 is the timer. This
patch adds the SOC initialization framework for 8064 and moves there
the related code.

arm: Redesign mainboard and SoC hooks for bootblock
This patch makes some slight changes to the way bootblock_cpu_init() and
bootblock_mainboard_init() are used on ARM. Experience has shown that
nearly every board needs either one or both of these hooks, so having
explicit Kconfigs for them has become unwieldy. Instead, this patch
implements them as a weak symbol that can be overridden by mainboard/SoC
code, as the more recent arm64_soc_init() is also doing.
Since the whole concept of a single "CPU" on ARM systems has kinda died
out, rename bootblock_cpu_init() to bootblock_soc_init(). (This had
already been done on Storm/ipq806x, which is now adjusted to directly
use the generic hook.) Also add a proper license header to
bootblock_common.h that was somehow missing.
Leaving non-ARM32 architectures out for now, since they are still using
the really old and weird x86 model of directly including a file. These
architectures should also eventually be aligned with the cleaner ARM32
model as they mature.

The new API is in use in depthcharge and is based around the "i2c_transfer"
function instead of i2c_read and i2c_write. The new function takes an array of
i2c_seg structures which represent each portion of the transfer after a start
bit and before the stop bit. If there's more than one segment, they're
seperated by repeated starts.
Some wrapper functions have also been added which make certain common
operations easy. These include reading or writing a byte from a register or
reading or writing a blob of raw data. The i2c device drivers generally use
these wrappers but can call the i2c_transfer function directly if the need
something different.
The tegra i2c driver was very similar to the one in depthcharge and was simple
to convert. The Exynos 5250 and 5420 drivers were ported from depthcharge and
replace the ones in coreboot. The Exynos 5420 driver was ported from the high
speed portion of the one in coreboot and was straightforward to port back. The
low speed portion and the Exynos 5250 drivers had been transplanted from U-Boot
and were replaced with the depthcharge implementation.

SPI flash as CBFS. Setting it for x86 will allow us to remove an
assumption about which SPI bus is used for this flash device.
Long term this can go away as we come up with a better abstraction
for the eventlog's backing store. This is only intended to help us

Old routine copied all of CAR region as-is right below CONFIG_RAMTOP.
Most of this region was reserved to interleave AP CPU address spaces
and unused on BSP CPU. The only part of CAR region requiring a copy
in RAM is the sysinfo structure.
Improved routine changes this as follows:
A region of size 'backup_size' below CONFIG_RAMTOP is cleared. In
case of S3 resume, OS context from this region is first copied to
high memory (CBMEM_ID_RESUME).
At stack switch, CAR stack is discarded. Top of the stack for BSP
is located at 'CONFIG_RAMTOP - car_size' for the remaining part
of the romstage. This region is part of 'backup_size' and was zeroed
before the switch took place.
Before CAR is torn down the region of CAR_GLOBALS (and CAR_CBMEM),
including the relevant sysinfo data for AP nodes memory training,
is copied at 'CONFIG_RAMTOP - car_size'.
NOTE: While CAR_GLOBAL variables are recovered, there are currently
no means to calculate their offsets in RAM.
NOTE: Boards with multiple CPU packages are likely already broken since
bbc880ee amdk8/amdfam10: Use CAR_GLOBAL for sysinfo
This moved the copy of sysinfo in RAM from above the stack to below
the stack, but code for AP CPU's was not adjusted accordingly.

The code in src/cpu/x86/mtrr/mtrr.c disables caching in a few places when
changing mtrr settings. While I can't find anything that says that's actually
required, I can believe it's necessary. With that said, other code around the
wrmsr instructions which actually modify the settings should be able to run
with caching enabled with no ill effects.
This is particularly true for two calls to printk, one in the fixed mtrr code
and one in the variable, which could result in an arbitrary amount of work
being done without caching. When changing the implementation of the cbmem
console, these two printks caused a significant regression in boot performance
on link of about 70ms which is about 10% of total firmware boot time. When the
window where the cache is disabled is minimized, both this and the new
implementation were about 30ms faster than the original boot time.
For the variable MTRRs, we now store what we want to set the MSRs to and then
write them all at once at the end of commit_var_mtrrs(). This way we don't

This is essentially a revert of commit 10bd772d. The CAR_MIGRATE
mechanism is only useful to migrate variables from a special region
(e.g. cache as RAM) into DRAM-backed CBMEM between different parts of
the romstage (it does not persist into ramstage). Since ARM devices use
SRAM for which there is no reason to become inaccessible in later parts
of the romstage, this mechanism isn't useful for them. Removing it makes
the romstage.ld script much simpler, which has the nice side-effect of
putting the BSS at the end of the memory image (so that cbfstool can
actually figure out that it doesn't need to be part of the ROM image).

There are ARM systems which are essentially heterogeneous multicores where
some cores implement a different ARM architecture version than other cores. A
specific example is the tegra124 which boots on an ARMv4 coprocessor while
most code, including most of the firmware, runs on the main ARMv7 core. To
support SOCs like this, the plan is to generalize the ARM architecture so that
all versions are available, and an SOC/CPU can then select what architecture
variant should be used for each component of the firmware; bootblock,
romstage, and ramstage.

ARM: Split out ARMv7 code and make it possible to have other arch versions.
We don't always want to use ARMv7 code when building for ARM, so we should
separate out the ARMv7 code so it can be excluded, and also make it possible
to include code for some other version of the architecture instead, all per
build component for cases where we need more than one architecture version
at a time.
The tegra124 bootblock will ultimately need to be ARMv4, but until we have
some ARMv4 code to switch over to we can leave it set to ARMv7.

Peppy had some issues with FUI. We decided it was time to create
peppy-specific gma.c and i915io.c files. Using yabel and the i915tool,
we generated a replay attack, then interpolated against the slippy
i915io.c to get something working.
Also, in preparation for moving code out of the mainboard gma.c to
generic driver code, we got rid of some hardcodes in the mainboard
gma.c that have no business being there. The worst were the
computation of gmch_[m,n] and it turns out that we had some
long-standing bugs related to confusion about 'bpp'. I've killed the
word bpp everywhere I could because there are at least 3 things that
correspond to bpp. We now have framebuffer, pipe, and panel bpp. The
names are long because I want to avoid all the mistakes we've all been
making in the last year :-) Sadly, that means a lot of changes not just
peppy-related, but they are simple and in a good cause.
The test pattern generation is driven by a global variable in
mainboard/peppy/gma.c. I've found in the past that it's very useful
to have a function like this available, as one can activate it while
using a jtag debugger: halt at the right place in ramstage, set the
variable to 1, continue. It's not enough code to worry about always
including.
The last hard-codes for M and N registers are gone, and the function
to set from generic intel_dp.c code works. To avoid screen trash on a
dev mode boot, which we liked but nobody else did :-), we now take the
time to put a pleasing background color that sort of doubles as a
power LED.
Rough timing is ramstage start is at 2.2, and dev setup is done at
3.3. These new platforms are depressingly slow to boot. Rom init alone
is taking 1.9 seconds. 13 years ago it was 3 seconds from power on to bash
prompt. These CPUs are at least 10x faster and take much longer to get going.
Future work, once we get this through, is to move more functions to the
intel driver, and combine the mainboard i915io.c into the mainboard gma.c.
That separation only existed because i915io.c was generated by a tool, and it
had lots of ugliness. Most ugliness is gone.

ways to do this. Unfortunately changing this ends up touching nearly
every Exynos5 file, but I hope you agree that it's worth it (and the
sooner we get it over with, the better... I can't bring myself to make
another device fit into that ugly scheme).
This also removes the redundant EXYNOS5 base address definitions from
the 5420 directory when there are EXYNOS5420 ones, to avoid complete
confusion. The new scheme tries to use EXYNOS5 for base addresses and
exynos5 for types that are common between the two processors, and
EXYNOS5420/exynos5420 for things that have changes (although I probably
didn't catch all differences).

This changes the number of chip selects that we configure from 2 to 1.
On current setups with (x16 memory 4Gbit chips) that means that we're
at 2GByte.
Technically we should add a second setting in the ares_ddr3_timings
and select between the two of the based on board strappings. That
would make the CONFIG_RUN_TIME_BANK_NUMBER work properly. I've
changed the ddr3_mem_ctrl_init() so it should handle that, but I'm not
actually doing the board strapping read right now.
This change means that accesses to 0xA0000000 - 0xFFFFFFFF on 2G
systems will no longer put the system in a messed up state (leading to
a hang). It also prevents some of the weird boot behavior that we've
seen that comes and goes depending on U-Boot alignment. See
<http://crosbug.com/p/20577>.

This patch intends to remove all code which enables hardware read
leveling. We need to disable h/w read leveling because new ASV table
is merged in kernel (which is based on the new characterization
condition) and new characterization environment has h/w read leveling
disabled, so we should also disable this. Also, disabling h/w read
leveling improves the MIF LVcc value (LVcc value is the value at which
DDR will fail to work properly), improve LVcc means we have enough
voltage margin for MIF. When h/w leveling is enabled, we have almost
zero volatge margin.

As per hardware recommendation, CKE PAD retention release must
happen just before gate leveling enable and only in case of resume.
Hence, this patch moves pad retention release from dmc_common.c to
dmc_init_ddr3_exynos5420.c. In addition to this we are providing
125 (+3 extra being safe) times auto refresh to DRAM by sending
REFA direct command. This is required because when CKE PAD retention
release happens, self refresh mode of DDR3 is disabled.
Hence, auto refresh 125 times.
This is ported from https://gerrit.chromium.org/gerrit/#/c/65573
Note: Since WAKEUP_DIRECT does not go thru memory init, it should be
safe to move CKE PAD retention out of bootblock.c.

alone don't seem to fix it. It's pretty fast anyway, so we just disable
the cache again for the duration of the IROM call.
Also removes a superfluous invalidation line from the bootblock code...
dcache_mmu_enable/disable already take care of that.

snow and pit: turn on FET4 (for SD card) at bootup
Explictly enable FET4 on Snow and Pit.
Historically we haven't needed to do this because:
* On snow there's a bypass around FET4 which effectively eliminates
it. Even if we don't turn on FET4 the SD card is still powered.
Turning on FET4 doesn't hurt though and is technically correct.
* On pit the EC turns on FET4 on cold bootup.
On pit we run into a problem if the kernel turns off FET4 like in
<https://gerrit.chromium.org/gerrit/#/c/65332/> and then we get a
software reset or warm reset. In this case the EC won't know to turn
it back on.

Provide functionality to create dynamic classes based on program name and
architecture for which the program needs to be compiled/linked. define_class
takes program_name and arch as its arguments and adds the program_name to
classes-y to create dynamic class. Also, compiler toolset is created for the
specified arch. All the files for this program can then be added to
program_name-y += .. Ensure that define_class is called before any files are
added to the class. Check subdirs-y for order of directory inclusion.
One such example of dynamic class is rmodules. Multiple rmodules can be used
which need to be compiled for different architectures. With dynamic classes,
this is possible.

We were running this loop 100 times with 5 ms delays. Change it
to run 500 times with 1 ms delays, which gives us the same
overall timeout but lets us bail out a bit sooner -- in practice,
at most, 4 ms sooner but every bit counts. Note, however, that
the tighter timing does reduce opportunities for threading. There
is a non-obvious set of tradeoffs on timeouts.

This patch enhances the armv7 exception handlers in Coreboot and

access the banked registers of SVC mode from a different exception mode,
it changes Coreboot (and its payloads) to run in System mode instead. As
both modes can execute all privileged instructions, this should not have
any noticeable effect on firmware operation (please correct me if I'm
wrong!).

c32b9b3 ("Set up caching in the bootblock.") had a bug where the
dcache and MMU remained enabled in the resume path. This caused
the machine to hang on resume. However, other bugs were preventing
us from testing this properly earlier on so it went unnoticed until
now.

On x86, cpu_info lives at the top of stack. Make the arm do that as
well, as the threading model needs that and so will multicore support.
As part of this change, make the stack size a power of 2.
Also make it much smaller -- 2048 bytes is PLENTY for ram stage.
Note that the small stack size is counterintuitive for rom stage. How
can this work in rom stage, which needs a HUGE stack for lzma? The
main use of STACK_SIZE has always been in ram stage; since 2002 or so
it was to size per-core stacks (see, e.g.,
src/arch/x86/lib/c_start.S:.space CONFIG_MAX_CPUS*CONFIG_STACK_SIZE
and, more recently, thread stacks. So, we define the STACK_TOP for rom
and ram stage, but the STACK_SIZE has no real effect on the ROM stage
(no hardware red zones on the stack) and hence we're ok with actually
defining the "wrong" stack size. In fact, the coreboot_ram ldscript
for armv7 sizes the stack by subtracting CONFIG_STACK_BOTTOM from
CONFIG_STACK_TOP, so we replicate that arithmetic in bootblock.inc
Observed stack usage in ramstage:
BS: BS_PAYLOAD_LOAD times (us): entry 1 run 153887 exit 1
Jumping to boot code at 23104044
CPU0: stack: 02072800 - 02073000, lowest used address 020728d4, stack used: 1836 bytes
entry = 23104044
Which means we do need 2K, not 1K.

Make all three coreboot stages (bootblock, romstage and ramstage) aware of the
architecture specific to that stage i.e. we will have CONFIG_ARCH variables for
each of the three stages. This allows us to have an SOC with any combination of
architectures and thus every stage can be made to run on a completely different
architecture independent of others. Thus, bootblock can have an x86 arch whereas
romstage and ramstage can have arm32 and arm64 arch respectively. These stage
specific CONFIG_ARCH_ variables enable us to select the proper set of toolchain
and compiler flags for every stage.
These options can be considered as either arch or modes eg: x86 running in
different modes or ARM having different arch types (v4, v7, v8). We have got rid
of the original CONFIG_ARCH option completely as every stage can have any
architecture of its own. Thus, almost all the components of coreboot are
identified as being part of one of the three stages (bootblock, romstage or
ramstage). The components which cannot be classified as such e.g. smm, rmodules
can have their own compiler toolset which is for now set to *_i386. Hence, all
special classes are treated in a similar way and the compiler toolset is defined
using create_class_compiler defined in Makefile.
In order to meet these requirements, changes have been made to CC, LD, OBJCOPY
and family to add CC_bootblock, CC_romstage, CC_ramstage and similarly others.
Additionally, CC_x86_32 and CC_armv7 handle all the special classes. All the
toolsets are defined using create_class_compiler.
Few additional macros have been introduced to identify the class to be used at
various points, e.g.: CC_$(class) derives the $(class) part from the name of
the stage being compiled.
We have also got rid of COREBOOT_COMPILER, COREBOOT_ASSEMBLER and COREBOOT_LINKER
as they do not make any sense for coreboot as a whole. All these attributes are
associated with each of the stages.

Since AGESA is stage-independent, we can build it just once, and use

We still keep the practice of specifying every single AGESA directory

this is needed due to the way AGESA builds.

Start using the rmodtool for generating rmodules.
rmodule_link() has been changed to create 2 rules:
one for the passed in <name>, the other for creating
<name>.rmod which is an ELF file in the format of
an rmodule.
Since the header is not compiled and linked together
with an rmodule there needs to be a way of marking
which symbol is the entry point. __rmodule_entry is
the symbol used for knowing the entry point. There
was a little churn in SMM modules to ensure an
rmodule entry point symbol takes a single argument.

Boot speeds can be sped up by mirroring the payload into
main memory before doing the actual loading. Systems that
would benefit from this are typically Intel ones whose SPI
are memory mapped. Without the SPI being cached all accesses
to the payload in SPI while being loaded result in uncacheable
accesses. Instead take advantage of the on-board SPI controller
which has an internal cache and prefetcher by copying 64-byte
cachelines using 32-bit word copies.

With the recent improvement 3d6ffe76f8,
speedup by CACHE_ROM is reduced a lot.
On the other hand this makes coreboot run out of MTRRs depending on
system configuration, hence screwing up I/O access and cache
coherency in worst cases.
CACHE_ROM requires the user to sanity check their boot output because
the feature is brittle. The working configuration is dependent on I/O
hole size, ram size, and chipset. Because of this the current
implementation can leave a system configured in an inconsistent state
leading to unexpected results such as poor performance and/or
inconsistent cache-coherency
Remove this as a buggy feature until we figure out how to do it properly
if necessary.

This change allows Kconfig options ROM_SIZE and CBFS_SIZE to be
set with values that are not power of 2. The region programmed
as WB cacheable will include all of ROM_SIZE.
Side-effects to consider:
Memory region below flash may be tagged WRPROT cacheable. As an
example, with ROM_SIZE of 12 MB, CACHE_ROM_SIZE would be 16 MB.
Since this can overlap CAR, we add an explicit test and fail
on compile should this happen. To work around this problem, one
needs to use CACHE_ROM_SIZE_OVERRIDE in the mainboard Kconfig and
define a smaller region for WB cache.
With this change flash regions outside CBFS are also tagged WRPROT
cacheable. This covers IFD and ME and sections ChromeOS may use.

Up until now, we relied on mksunxiboot to prepend the header which
makes coreboot.rom bootable on Allwinner SoCs. If that tool was not
present, the build silently failed.
Integrate this tool into our util/ package, so that we do not have to
rely on mksunxiboot being in PATH.
Our version of mksunxiboot also eliminates some limitations of the
original tool, so we no longer have to use 'dd' to limit the file

This re-factors clock_get_periph_rate() to be a simpler and also
make a few corrections along the way. To summarize:
- clk_bit_info is no longer used. It had numerous errors and was
really painful anyway since it was just a bunch of opaque magic
numbers that made bugs non-obvious.
- Clock source bitfields for peripherals handled in the switch
statement are 3 bits, not 4. Some divider values are 3 bits,
some are 4. The earlier code always assumed 4 bits for both
which included reserved bits in many cases.
- UART source clock and divider shift values were wrong.
- PWM clock divider was being read from the wrong register.
- SPI3 divider value was being read from the wrong register.
- There was a really confusing calculation for SDMMC0 and SDMMC2
clock rates, but it was never actually used since the switch
statement never handled PERIPH_ID_SDMMC{0,2} and would thus
return if they were ever passed into this function.

For example, the inner function runs differently if we're using 8 bits

requires SD_0_CDn to be an output rather than alternate function and
must have a value set.

This includes the new dp code, which is better, and the fimd code,
which is changed and improved. We took the chance to remove un-needed
files, and also to remove some foolish u-boot habits, but not all of
them. That will take time.
With these changes we get graphics.
Since the only mainboards we have with 16 bit graphics are 5:6:5,
adjust edid.c to just use that format. If at some future time we need
4:4:4, which seems unlikely, we'll need to add a function to adjust
the lb_framebuffer. Note that you can't just divine this from the EDID,
as the graphics pipe format need not match the actual final format used.
The EDID reading works. We've been requested to support hard-coded
EDIDs and that will come in the next revision. Currently the hard-coded
EDID is ignored for testing.

included in CBFS. This happens when either CPU_MICROCODE_CBFS_GENERATE or
CPU_MICROCODE_CBFS_EXTERNAL is selected, however, the makefile checked that
CPU_MICROCODE_IN_CBFS was selected instead. The end result was that on
hasswell, the UPDATE-FIT step was always run, even when no microcode was
included, generating a build error.
Instead, introduce a new variable which tells if a microcode update is
added in CBFS during the build.

Commit * bdafcfa Add the Intel FSP 206ax CPU core support
Introduced this option. This option was meant to have a board generate
a CBFS file containing microcode. However, microcode generation used to be
enabled by default when CPU_MICROCODE_IN_CBFS was selected.
The introduction of BOARD_MICROCODE_CBFS_GENERATE killed that automatic
default, which is not what we want. This option is misguided in the sense
that it tends to introduce a non-default which had been intentionally a
default. We now have to select two Kconfig options in order to generate
microcode in CBFS, meaning one option is redundant.

On haswell ULT systems there is a 24MHz clock that continuously runs
when deep package c-states are entered. The 100MHz BCLK is shut down
in the lower c-states. When the package wakes back up a conversion
formula needs to be applied. The 24MHz calibration is done using the
internal PCODE unit.

The c-states are configured according to the BWG, however the
package c-states are disabled as they currently cause platform
instability. The exposed ACPI c-state to processor c-state mapping
are as follows for ULT boards:
ACPI(C1) = MWAIT(C1E)
ACPI(C2) = MWAIT(C7S long latency)
ACPI(C3) = MWAIT(C10)
The non-ULT boards have an expoed c-state mapping:
ACPI(C1) = MWAIT(C1E)
ACPI(C2) = MWAIT(C3)
ACPI(C3) = MWAIT(C7S)
Included in this patch is removing the updating of current limit
registers as some of the MSRs are different and the proper values
are currently unknown. Lastly, some of the MSRs were renamed to
match the BWG.
Booted 3.8 kernel and used powertop to note package, core, and acpi

The recommendation from Intel is to report each core as a
separate logical domain in the _PSD table.
This goes against the recommendation in the ACPI specification
because all of these cores are on the same package and share a
VR so they will do voltage transitions together.
The reasoning is that with a larger number of logical processors
the P-state often ramps too quickly resulting in higher power
consumption. By exposing each core as a separate domain the OS
can manage them individually allowing the socket to select the
optimum frequency.

to the Family 15tn APU, the Parmer platform, and the Hudson FCH. The
dsdt.asl file in the mainboard directory contains only #include
references to the appropriate files.
Initially, this split was done by moving each piece of functionality
into its own file (e.g. IRQ routing and mapping, processor tree, sleep
states and sleep methods, etc.) and those pieces were #included in
dsdt.asl to ensure an exact match (via acpidump/acpixtract/iasl -d)
with the extant version of the table. Once the new tables were found
to exactly match the existing tables, the pieces were rearranged into
reasonable groups (e.g. fch.asl, northbridge.asl, pci_int.asl, etc.).
Some include files have no content but are left as a template for
other platforms and as placeholders for completing the ACPI
implementation for Parmer (e.g. thermal.asl, superio.asl, ide.asl,

The SPI module in Exynos 5420 didn't follow Coreboot's SPI API standard
(spi-generic.h) and will be a problem when we want to share SPI drivers.
This commit replaces exynos_spi_* by spi_* functions.
Note, exynos_spi_read is kept and changed to a static function because its usage
is different from the standard API "spi_xfer".

The 5420 clock code still had a data structure in it for the 5250 clock
registers which was used by some of the clock functions. That caused some
clocks to be configured incorrectly, specifically the i2c clock which was
running at about 80KHz instead of about 600KHz as configured by U-Boot.
Also, the registers and bit positions used to set up the SPI bus were not
consistent with U-Boot, and if the bus clock rate were set to 50MHz, a rate
which has historically worked on snow, loading would fail. With these fixes
the clock rate can be set to 50MHz and the device boots as much as is
expected. I haven't yet measured the actual frequency of the bus to verify
that it's now being calculated correctly.

The pinmux code for the exynos5250 was all bundled into a single, large
function which contained a switch statement that would set up the pins for
different peripherals within the SOC. There was also a "flags" parameter, the
meaning of which, if any, depended on which peripheral was being set up.
There are several problems with that approach. First, the code is inefficient
in both time and space. The caller knows which peripheral it wants to set up,
but that information is encoded in a constant which has to be unpacked within
the function before any action can be taken. If there were a function per
peripheral, that information would be implicit. Also, the compiler and linker
are forced to include the entire function with all its cases even if most of
them are never called. If each peripheral was a function, the unused ones
could be garbage collected.
Second, it would be possible to try to set up a peripheral which that function
doesn't know about, so there has to be additional error checking/handling. If
each peripheral had a function, the fact that there was a function to call at
all would imply that the call would be understood.
Third, the flags parameter is fairly opaque, usually doesn't do anything, and
sometimes has to have multiple values embedded in it. By having separate
functions, you can have only the parameters you actually want, give them
names that make sense, and pass in values directly.
Fourth, having one giant function pretends to be a generic, portable API, but
in reality, the only way it's useful is to call it with constants which are
specific to a particular implementation of that API. It's highly unlikely that
a bit of code will need to set up a peripheral but have no idea what that
peripheral actually is.
Call sights for the prior pinmux API have been updated. Also, pinmux
initialization within the i2c driver was moved to be in the board setup code
where it really probably belongs. The function block that implements the I2C
controller may be shared between multiple SOCs (and in fact is), and those
SOCs may have different pinmuxes (which they do).
Other places this same sort of change can be made are the pinmux code for the
5420, and the clock configuration code for both the 5250 and the 5420.

Now that we are executing VbInit() in coreboot we can end up
in a situation where the recovery reason is consumed during

during ramstage EC init, thereby losing the recovery reason.
Two possiblities are to remove the EC check+reboot from ramstage
and let it happen in depthcharge. This however means that the
system has to boot all the way into depthcharge and then reboot
the EC and the system again.
Instead if we do a check in romstage before VbInit() is called
then we can reboot the EC into RO early and avoid booting all
the way to depthcharge first.
This change adds a ramstage version the EC init function and

When starting the Exynos5250 port, a lot of unneeded u-boot code
was imported. This is an attempt to get rid of a lot of unneeded
code before the port is used as a basis for further ARM ports.
There is a lot more that can be done, including cleaning up the
5250's Kconfig file.

It turns out that the exynos5-common code previously imported from
u-boot is not common code at all but very specific to the 5250 and
not compatible with the 5450. Hence, unify the directories exynos5250
and exynos5-common. We will try to factor out common code while
progressing with the 5450 port.

This patch unfortunately incorporates a number of changes,
all of which are making future ARM ports easier.
- drop cruft that came in with u-boot
- move serial console from mainboard Kconfig to Exynos Kconfig
- factor out non-board specific wakeup code
- move generic bootblock code from mainboard to Exynos
- actually call arch_cpu_init()
- remove dead code
- fix up copyright messages
- remove snow_ prefix from a lot of code to reduce the noise
when creating a new mainboard based on that code.

AMD_SB_SPI_TX_LEN is defined in 'src/southbridge/amd/Kconfig'

southbridges that support larger size.
I have tested on AMD Parmer and Thatcher. We will release a new board

Loading on an OMAP SOC requires that the first sector of the image have a
configuration header, and, when not an execute in place image, an additional
header which describes how big the image is and where it should be loaded.
This change adds some infrastructure to statically build that header using C
code, and to paste the header onto the front of coreboot.rom in a new top
level target file called MLO.
The configuration header we're using is as inert as possible, in line with
what U-Boot is doing. I think it could be used to give additional
configuration parameters to the built-in ROM on the SOC, but we don't need to
do that, and there didn't seem to be any actual documentation how to do that.
Because the header is built from C and is defined per CPU, it would be
possible to include extra settings in other CPUs if desired.
Adding a new top level build target is a bit disruptive, but should be
contained to the am335x directory and not interfere with other mainboards.

There are some boards that do a significant amount of
work after cache-as-ram is torn down but before ramstage

is one such operation. However, there are pieces of code
that are executed that reference global variables that
are linked in the cache-as-ram region. If those variables
are referenced after cache-as-ram is torn down then the
values observed will most likely be incorrect.
Therefore provide a Kconfig option to select cache-as-ram
migration to memory using cbmem. This option is named
CAR_MIGRATION. When enabled, the address of cache-as-ram
variables may be obtained dynamically. Additionally,
when cache-as-ram migration occurs the cache-as-ram
data region for global variables is copied into cbmem.
There are also automatic callbacks for other modules
to perform their own migration, if necessary.

Since the TSC udelay() function can be used in SMM that means the

TSC rollover properly. In most cases this should not matter as the TSC
typically starts ticking at value 0, and it would take a very long time
to roll it over. However, it is my understanding that this behavior is
not guaranteed. Theoretically the TSC could start or be be written to
with a large value that would cause the rollover.

the local apic for udelay() in ramstage is to not have to pay the
penalty of calibrating the TSC frequency. Therefore provide a
TSC_CONSTANT_RATE option to indicate that TSC calibration is not
needed. Instead rely on the presence of a tsc_freq_mhz() function
provided by the cpu/board. Additionally, assume that if
TSC_CONSTANT_RATE is selected the udelay() function in SMM will
be the tsc.

time.h We Hardly Knew Ye.
This deprecates time.h which is currently only used by Exynos5250 and
Snow. The original idea was to try and unify some of the various timer
interfaces and has been supplanted by the monotonic timer API.
timer_us() is now obsolete. timer_start() is now mct_start() and

On x86 systems there is a concept of cachings the ROM. However,
the typical policy is that the boot cpu is the only one with
it enabled. In order to ensure the MTRRs are the same across cores
the rom cache needs to be disabled prior to OS resume or boot handoff.
Therefore, utilize the boot state callbacks to schedule the disabling
of the ROM cache at the ramstage exit points.

Add a safety check in function `intel_update_microcode` to return when
accidentally `NULL` is passed as `microcode_updates`, which would lead
to a null pointer dereference later on.
for (c = microcode_updates; m->hdrver; m = (const struct microcode *)c) {
While at it, use `return NULL` for clarity in function
`intel_microcode_find` and include the header file `stddef.h`. for it.
The review of this patch had some more discussion on adding more
comments and more detailed error messages. But this should be done in
a separate patch.
For clarity here some history, on how this was found and what caused
the discussion and confusion.
Originally when Vladimir made this improvement, selecting
`CPU_MICROCODE_IN_CBFS` in Kconfig but not having the microcode blob
`cpu_microcode_blob.bin` in CBFS resulted in a null pointer dereference
later on causing a crash.
for (c = microcode_updates; m->hdrver; m = (const struct microcode *)c) {
Vladimir fixed this by returning if `microcode_updates` is `NULL`,
that means no file is found and successfully tested this on his
Lenovo X201.
When pushing the patch to Gerrit for review, the code was rewritten
though by Aaron in commit »intel microcode: split up microcode loading
stages« (98ffb426) [1], which also returns when no file is found. So
the other parts of the code were checked and the safety check as
described above is added.

This makes sure that the product ID (PRO_ID) register can be read
when the OS kernel is figuring out what kind of CPU it's running on.
For historical reference, the original U-Boot code seems to have
worked basically by accident here. The hardware has a quirk where by
reading the value before gating the IP block keeps the value
persistent. U-Boot reads the chip ID early on to distinguish between
chip family, but we do not mix code the same way so we do not read
the chip ID. Since the value has been read before the clock gating
happens, the value remains available for the kernel to use during the
decompression stage. We don't want to rely on that behavior when using
coreboot. Instead the kernel should gate unused IPs.

This gets rid of the clock-tick based sdelay in favor of udelay().
udelay() is more consistent and easier to work with, and this allows
us to carry one less variation of timers (and headers and sources...).
Every 1 unit in the sdelay() argument was assumed to cause a delay of
2 clock ticks (@1.7GHz). So the conversion factor is roughly:
sdelay(N) = udelay(((N * 2) / 1.7 * 10^9) * 10^6)
= udelay((N * 2) / (1.7 * 10^3))
The sdelay() periods used were:
sdelay(100) --> udelay(1)
sdelay(0x10000) --> udelay(78) (rounded up to udelay(100))
There was one instance of sdelay(10000), which looked like sort of a
typo since sdelay(0x10000) was used elsewhere. sdelay(10000) should
approximate to about 12us, so we'll stick with that for now and leave
a note.

Add a microsecond timer, its declaration, the function to start it,
and its usage. To start it, one calls timer_start(). From that point
on, one can call timer_us() to find microseconds since the timer was
started.
We show its use in the bootblock. You want it started very early.
Finally, the delay.h change having been (ironically) delayed, we
create time.h and have it hold one declaration, for the timer_us() and
timer_start() prototype.
We feel that these two functions should become the hardware specific
functions, allowing us to finally move udelay() into src/lib where it
belongs.

Split the Persimmon DSDT into common code areas.
For example, split the Southbridge specific code into
the Southbridge directory and CPU specific code into
the CPU directory. Also adding the superio.asl file
to the Persimmon DSDT tree. This file is empty for
the moment but will be necessary in the future. I have
also emptied the thermal.asl file in the mainboard
directory because it does not seem to perform as
intended (fan control does not change when it is
brought back into the code base) and it has been
inside a '#if 0' statement for a long time. Removing
it until it is decided that it is actually necessary.
This change was verified in three different ways:
1. Visual comparison of the compiled DSDT pulled from the
Persimmon after booting into Linux using the ACPI tools
acpidump, acpixtract, and iasl. The comparison was done
between the DSDT before and after doing the split work.
This test is somewhat difficult considering the expanse
of the changes. Blocks of code have been moved, and
others changed.
2. Linux logs were dumped before and after the DSDT split.
Logs dumped and compared include dmesg and lspci -tv.
Neither log changed significantly between the two compare
points.
3. The test suite FWTS was run on the Coreboot build both
before and after doing the DSDT split with the command
'sudo fwts -b -P -u'. The flag -b specifies all batch jobs,
-P specifies all power tests, and -u specifies utilities.
Interactive jobs were not run as most of them consist of
laptop checks. Again, there were no significant changes
between the two endpoints.
These tests lead me to believe that there was no change in
the functionality of the ACPI tables apart from what is
known and expected.
This patch is the first of a series of patches to split the DSDT.
The ASRock patch was merged before this one and breaks the ASROCK
E350M1 build (patch 8d80a3fb: http://review.coreboot.org/#/c/3050/).

This enables type checking for safety as to help prevent errors like
http://review.coreboot.org/#/c/3038/ . Now compilation fails if the
wrong type is passed into readb/readw/readl/writeb/writew/writel
or other macros in io.h.
This also deprecates readw/writew. The previous definition was 16-bits
which is incorrect since wordsize on ARMv7 is 32-bits and there was
only 1 instance of writew (#if 0'd anyway). Going forward we should
always use read{8,16,32} and write{8,16,32} where N specifies the
exact length rather than relying on ambiguous definition of wordsize.
Since many macros relied on __raw_*, which were basically the same
(minus data memory barrier instructions), this patch also gets rid
of __raw_*. There were parts of the code which ended up using these
macros consecutively, for example:
setbits_le32(®s->ch_cfg, SPI_CH_RST);
clrbits_le32(®s->ch_cfg, SPI_CH_RST);
In such cases the safe versions of readl() and writel() should be
used anyway.
Note: This also fixes two dubious casts as to avoid breaking
compilation.

The existing header was imported along with the Exynos code and left
mostly unchanged. This is the first patch in a series intended to
replace the imported u-boot I2C API with a much simpler and cleaner
interface:
- We only need to expose i2c_read() and i2c_write() in our public API.
Everything else is board/chip-dependent and should remain hidden
away.
- i2c_read and i2c_write functions will take bus number as an arg
and we'll eliminate i2c_get_bus and i2c_set_bus. Those are prone to
error and end up cluttering the code since the user needs to save
the old bus number, set the new one, do the read/write, and restore
the old value (3 added steps to do a simple transaction).
- Stop setting default values for board-specific things like SPD
and RTC bus numbers (as if we always have an SPD or RTC on I2C).
- Death to all the trivial inline wrappers. And in case there was any
doubt, we really don't care about the MPC8xx. Though if we did then
we would not pollute the public API with its idiosyncrasies.
