walkcbfs() is used only with ROMCC. Besides finding stages during the
bootblock, it's also used when applying microcode updates during the
bootblock phase. The function used to return only a pointer to the data of
the CBFS file, while making the header completely inaccessible. Since the
header contains the length of the CBFS file, the caller did not have a way
to know how long the data was. Then, other conventions had to be used to
determine the EOF, which might present problems if the user replaces the
CBFS file. This is not an issue when jumping to a stage (romstage), but can
present problems when accessing a microcode file which has not been
NULL-terminated.
Refactor walkcbfs_asm to return a pointer to the CBFS file header rather
than the data. Rename walkcbfs() to walkcbfs_head(), and reimplement a new
walkcbfs() based on walkcbfs_head(). Thus current usage of walkcbfs()
remains unaffected.
The code has been verified to run successfully under qemu.
Subsequent patches will change usage of walkcbfs() to walkcbfs_head where
knowing the length of the data is needed.

During the update_fit step, 'file_length' is used to determine how many
bytes are left in the CBFS file. It was decremented in a loop from an
array 'mcus[num_mcus].size', but 'num_mcus' was incremented right before.
Since 'mcus' is memset(0) externally, 'file_length' was never decremented.
The loop exited when it reached a dummy terminator, usually 48 bytes of 0
which are internationally added to microcode blobs in coreboot. However,
if that terminator is removed, the loop doesn't stop and continues until
it segfaults.

LinuxBIOS was a out-of-date name. It needs to be changed it to Coreboot.
And the new document is not specific to AMD, so we get rid of the AMD64 from

This is a separate patch for the renaming.
LinuxBIOS-AMD64.tex was still about SVN and buildtarget. Later patch
will come up for updating those old thing. And this new document,
CorebootBuildingGuide.tex, is planning to be only about building.

Limit power to 12W at 73C and remove limit at 68C.
To have the CPU consume maximum power it is necessary to stress
both the CPU and the GPU. Bastion (chrome.supergiantgames.com)
and/or webglsamples.googlecode.com can be useful for this.
Testing this properly requires a script to report the running
average power readings. The watch_power.sh script is attached
to this issue in the partner tracker.
1) Run watch_power.sh continuously:
localhost ~ # watch -n 0 bash -e /tmp/watch_power.sh
2) Start Bastion (or other stress apps). The power draw should
be close to 15W if under enough load.
3) Watch until temperature climbs above 73C and is caught by
the thermal zone 10 second poll, this can be sped up by blocking
or removing the fan.
4) The ACPI thermal zone states should change to reflect that
active[2] is now enabled and power consumption should drop to 12W.
5) Stop the stress apps and wait until the CPU cools off again,
enable the fan again if it was removed.
6) The ACPI thermal zone state should switch back to active[3].

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

effect that make stops caring about flags added in makefile itself. Undef
as many variables as possible but still pass them to configure for them to
have correct effect and keep CC assignment as my make version doesn't undefine

The cause of this issue is:
USB devices use bit 11(0x0b) of GP0_STS represents S3 wake up event,
but this bit is not clear after wake up. So OS thinks there is a
wake up signal and wake up immediately.
Both amd/olivehill and asrock/imb-a180 have been validated.

The AML code of PTS and WAK for southbridge are in
UINT8 AlibSsdtKB[], Proc/GNB/Modules/GnbInitKB/AlibSsdtKB.h.
It was integrated into SSDT even it was called by nobody.
The source ASL was provided by AGESA for reference, but it
has been scrubbed when it was ported to Coreboot.
Without the calls, Olive Hill can not wake up if it boots Windows.
Both amd/olivehill and asrock/imb-a180 have been validated.

The bug is hard to find. We were adding the feature of fan control. We
met some strange things which could not be explained. Like, sometimes
adding printk let the error disappear. Then we traced the code by hardware
debug tool (HDT). It turned out the data in stack was overwritten.
The values of AccessWidthxx are
{ AccessWidth8 = 1,
AccessWidth16,
AccessWidth32,}
For the case of AccessWidth8, we only need to access the index/data
once. But ReadECmsg and WriteECmsg did the loop twice, 1 more time
than they are supposed to do. The data in stack next to "Value" would
be overwritten.
For all the cases, the code should be
OpFlag = OpFlag & 0x7f;
switch (OpFlag) {
case 1: /* AccessWidth8 */
OpFlag = 0;break;
case 2: /* AccessWidth16 */
OpFlag = 1;break;
case 3: /* AccessWidth32 */
OpFlag = 3;break;
case 4: /* AccessWidth64 */
OpFlag = 7;break;
default:
error;
}
Actually, the caller only takes AccessWidth8 as the parameter. We can ignore other
cases for now.
That is an AGESA bug. AMD's AGESA team own this code. They have given the
response that they are going to update this in next release. I presume let them
decide the proper way to fix that. Before that, I change the code as little
as possible to make it run without crash.

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.

mainboard_smi_gpi has recently been updated to take a u32 argument from a
u16, but the patch introducing the fsp_bd82x6x support has been verified
on a master before this change, thus resulting in a 'cast from incompatible
type' error. Update the pointer to the correct size argument.
