asrock/e350m1: reduce default stack size
The stack used on the ASRock E350M1 is significantly less than
what we currently set (64k per core). In fact, we use about half
of the default stack size (4k) on core 0 and even less on non
BSP cores [1]:
$ grep stack coreboot_without_patch_but_monotonic_timer.log
CPU1: stack_base 002a0000, stack_end 002afff8
CPU1: stack: 002a0000 - 002b0000, lowest used address 002afda8, stack used: 600 bytes

these seem to be too much too.

Since the TSC udelay() function can be used in SMM that means the
TSC can count up to whatever value. The current loop was not handling
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.

In order to properly sequence the boot state machine it's
important that outside code can block the transition from
one state to the next. When timers are not involved there's
no reason for any of the existing code to block a state
transition. However, if there is a timer callback that needs to
complete by a certain point in the boot sequence it is necessary
to place a block for the given state.
To that end, 4 new functions are added to provide the API for
blocking a state.
1. boot_state_block(boot_state_t state, boot_state_sequence_t seq);
2. boot_state_unblock(boot_state_t state, boot_state_sequence_t seq);
3. boot_state_current_block(void);

Some boards use the local apic for udelay(), but they also provide
their own implementation of udelay() for SMM. The reason for using
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.

The current way to get a simple mono_time difference is:
1. Declare a rela_time struct
2. Assign it the value of mono_time_diff(t1, t2)
3. Get microseconds from it using rela_time_in_microseconds().
This patch adds a simpler method. Now one only needs to call
mono_time_diff_microseconds(t1, t2) to obtain the same value which
is produced from the above three steps.

The "gigabit ethernet controller" (GEC) block was added to AMD
Hudson A55E to integrate ethernet capabilities into an AMD
southbridge.
The GEC is designed to work with B50610 and B50610M gigabit PHY
chips from Broadcom. These parts may not be generally available
in small quantities for embedded development.
The GEC block requires an opaque firmware blob to function. The
GEC blob is controlled by AMD and Broadcom and is not available
from coreboot.org.
This change removes GEC support from AMD Parmer and AMD Thatcher
mainboards since these boards do not have the Broadcom PHY.
AMD has requested that the GEC be hidden for Hudson FCH since
the PHY parts are not generally available. This Kconfig option
can make it appear that this is a viable and supported way to
add Ethernet to an embedded board. It is possible to use the
Hudson GEC block with other PHYs, but this requires development
of a custom GEC blob and a custom Ethernet driver. A custom GEC
blob has been developed for a Micrel PHY, but there is no
accompanying driver.

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

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.
(credit to Gabe for finding symptom in the kernel)

`src/southbridge/amd/cimx/sb800/` is passed with the switch `-I` to
the compiler, where it is also going to find the header file
`sb_cimx.h`. Therefore use `#include <sb_cimx>` everywhere, which is
what some AMD SB800 based boards already do.
The only effect is, that the compiler will not needlessly look into
directories which do not contain the header file [1].
The following command was used for the replacement.
$ git grep -l sb_cimx.h src/mainboard/ | xargs sed -i 's/#include "sb_cimx.h"/#include <sb_cimx.h>/'

Because pointers can be 32bit or 64bit big,
using them in the coreboot table requires the
OS and the firmware to operate in the same mode
which is not always the case. Hence, use 64bit
for all pointers stored in the coreboot table.
Guess we'll have to fix this up once we port to
the first 128bit machines.

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.

This removes the wait_ms argument from the dp_controller_init(). The
only delay involved is a constant 60ms delay that happens if
everything else goes well. This delay is derived from the LCD spec
so there's no reason it should be baked into the controller code.
(This patch also has the side-effect of fixing a bug where we were
delaying on an undefined value for wait_ms).

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.

ACPI reported the entire space between top-of-memory and some

the HyperTransport configuration disagreed. Make them match up.
Other boards are not affected since they don't report any region
for that purpose at all (it seems).

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/).
Please be aware of this dependency when pulling these patches.

We need these to be inputs so they can be read when populating the coreboot

gate capacitance has had a chance to charge, and if we decide to use
actually use that information during the ROM stage to do earlier RW
firmware selection.
It is not guarded by a ChromeOS config variable because those lines are
always intended to be input GPIOs, regardless of whether we're running
ChromeOS or not.

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.

This re-factors the Exynos5 I2C code to be simpler and use the

- i2c_read() and i2c_write() functions updated to take bus number
as an argument.
- Get rid of the EEPROM_ADDR_OVERFLOW stuff in i2c_read() and
i2c_write(). If a chip needs special handling we should take care
of it elsewhere, not in every low-level i2c driver.
- All the confusing bus config functions eliminated. No more
i2c_set_early_config() or i2c_set_bus() or i2c_get_bus(). All this
is handled automatically when the caller does a transaction and
specifies the desired bus number.
- i2c_probe() eliminated. We're not a command-line utility.
- Let the compiler place static variables automatically. We don't need
any of this fancy manual data placement.
- Remove dead code while we're at it. This stuff was ported early on
and much of it was left commented out in case we needed it. Some
also includes nested macros which caused gcc to complain.
- Clean up #includes (no more common.h, woohoo!), replace debug() with
printk().

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.

The MP code on haswell was mirroring the BSPs MTRRs. In addition it
was cleaning up the ROM cache so that the MTRR register values were
the same once the OS was booted. Since the hyperthread sibling of
the BSP was going through this path the ROM cache was getting torn
down once the hyperthread was brought up.
That said, there was no differnce in observed boot time keeping the
ROM cache enabled.

On certain architectures such as x86 the bootstrap processor

to ensure that the caching enablement of the ROM is disabled so that
the caching settings are symmetric before booting the payload or OS.
Tested this on an x86 machine that turned on ROM caching. Linux did not
complain about asymmetric MTRR settings nor did the ROM show up as

This adds configuration of SerialIO devices in the Lynxpoint-LP
chipset. This includes DMA, I2C, SPI, UART, and SDIO controllers.
There is assorted magic setup necessary for the devices and
while it is similar for each device there are subtle differences
in some register settings.
These devices must be put into "ACPI Mode" in order to take
advantage of S0ix. When in ACPI mode the allocated PCI BARs
must be passed to ACPI so it can be relayed to the OS. When
the devices are in ACPI mode BAR0+BAR1 is saved into ACPI NVS
and then updated and returned when the OS calls _CRS.
Note that is is not entirely complete yet. We need to update
the IASL compiler in our build environment to support ACPI 5.0
in order to be able to pass the FixedDMA entries to the kernel.
There are also no ACPI methods defined yet to do D0->D3->D0
transitions for actually entering/exiting S0ix states.
This is hard to test right now because our kernel does not support
any of these devices in ACPI mode. I was able to build and test
the upstream bleeding-edge branch of the linux-pm git tree. With
that tree I was able to enumerate and load the driver for the
DesignWare I2C driver and attempt to probe the I2C bus -- although
there are no devices attatched.
I am also able to see the resources from ACPI in /proc/iomem get
reserved properly in the kernel.

The new enable_pm1() function was doing 2 things wrong:
1. It was doing a RMW of the pm1 register. This means we were
keeping around the enables from the OS during S3 resume. This
is bad in the face of the RTC alarm waking us up because it would
cause an infinite stream of SMIs.
2. The register size of PM1_EN is 16-bits. However, the previous
implementation was accessing it as a 32-bit register.
The PM1 enables should only be set to what we expect to handle in the
firmware before the OS changes to ACPI mode.

Previously southbridge_smm_init() was provided that did both
the clearing of the SMM state and enabling SMIs. This is
troublesome in how haswell machines bring up the APs. The BSP
enters SMM once to determine if parallel SMM relocation is possible.
If it is possible the BSP releases the APs to do SMM relocation.
Normally, after the APs complete the SMM relocation, the BSP would then
re-enter the relocation handler to relocate its own SMM space.
However, because SMIs were previously enabled it is possible for an SMI
event to occur before the APs are complete or have entered the
relocation handler. This is bad because the BSP will turn off parallel
SMM save state. Additionally, this is a problem because the relocation
handler is not written to handle regular SMIs which can cause an
SMI storm which effectively looks like a hung machine. Correct these
issues by turning on SMIs after all the SMM relocation has occurred.

When calculating the offsets of the various binary blobs within the
coreboot.rom file, we noticed that using mawk as the awk tool instead
of using gawk led to build issues. This was finally traced to the
maximum value of the unsigned long variables within mawk - 0x7fff_ffff.
Because we were doing calculations on values up in the 0xffxxxxxx
range, these numbers would either be turned into floating point values
and printed using scientific notation, or truncated at 0x7fff_ffff.
To fix this, we print the values out as floating point, with no decimal
digits. This works in gawk, mawk, and original-awk and as the testing
below show, seems to be the best way to do this.
printf %u 0xFFFFFFFF | awk '{printf("%.0f %u %d", $1 , $1 , $1 )}'
mawk: 4294967295 2147483647 2147483647
original-awk: 4294967295 2147483648 4294967295
gawk: 4294967295 4294967295 4294967295
The issue of %d not matching gawk and original-awk has been reported
to ubuntu.
In the future, I'd recommend that whenever awk is used, a format is
specified. It doesn't seem that we can count on the representation
being the same between the different versions.

src/mainboard/asrock/e350m1/PlatformGnbPcie.c:131:5: warning: 'return' with a value, in function returning void [enabled by default]
[…]
The function signature is (the return type might not be part of this though [1]),
VOID
OemCustomizeInitEarly (
IN OUT AMD_EARLY_PARAMS *InitEarly
)
so do not return anything.
All other AMD Family 14 boards already have the correct code. For example
following commit fixed this for AMD Persimmon.

There is an optimization that can take place when hole
carving in ranges above 4GiB. If the range is the last
range then there is no need to carve UC holes out from
the larger WB range.
This optimization also has the same assumption of choosing
WB as the default MTRR type: the OS needs to properly
handle accessing realloacted MMIO resources with PAT so
that the MTRR type can be overidden.
Below are results using a combination of options. The
board this was tested on has 10 variable MTRRs at its
disposal. It has 4GiB of RAM.

Some ranges would use less variable MTRRs if an UC area
can be carved off the top of larger WB range. Implement this
approach by doing 3 passes over each region in the addres space:
1. UC default type. Cover non-UC and non-WB regions with respectie type.
Punch UC hole at upper end of larger WB regions with WB type.
2. UC default type. Cover non-UC regions with respective type.
3. WB default type. Cover non-WB regions with respective type.
The hole at upper end of a region uses the same min alignment of 64MiB.

Two convenience functions are added to operate on a range_entry:
- range_entry_update_tag() - update the entry's tag
- memranges_next_entry() - get the next entry after the one provide
These functions will be used by a follow on patch to the MTRR code
to allow hole punching in WB region when the default MTRR type is
UC.

Downstream payloads may need to take advantage of caching the
ROM for performance reasons. Add the ability to communicate the
variable range MTRR index to use to perform the caching enablement.
An example usage implementation would be to obtain the variable MTRR
index that covers the ROM from the coreboot tables. Then one would
disable caching and change the MTRR type from uncacheable to
write-protect and enable caching. The opposite sequence is required
to tearn down the caching.

The CONFIG_CACHE_ROM support in the MTRR code allocates an MTRR
specifically for setting up write-protect cachine of the ROM. It is
assumed that CONFIG_ROM_SIZE is the size of the ROM and the whole
area should be cached just under 4GiB. If enabled, the MTRR code
will allocate but not enable rom caching. It is up to the callers
of the MTRR code to explicitly enable (and disable afterwards) through
the use of 2 new functions:
- x86_mtrr_enable_rom_caching()
- x86_mtrr_disable_rom_caching()
Additionally, the CACHE_ROM option is exposed to the config menu so
that it is not just selected by the chipset or board. The reasoning
is that through a multitude of options CACHE_ROM may not be appropriate
for enabling.

The memrange infrastructure will serve as a shared implementation
