While that microcode is licensed under a permissive free software
license we don't have any corresponding source code, so until someone
produces that source code we need to treat it as nonfree software.
This issue was introduced by the commit the
f7c0fec698 ("coreboot/fam15h: update
code base, deblob, unset CONFIG_STM (see bug #64535)") and is also
present in GNU Boot 0.1 RC1.

In coreboot this build option is used to download nonfree software so
they can be included later on in the builds.
It doesn't necessarily means that nonfree software ends up in the
images but it is way easier and safer to disable that than having to
audit precisely what happen for each computer and build configuration.

These folders (fam15h_rdimm and fam15h_udimm) are generic plateforms to gather
patches in common for multiple boards (e.g. kgpe-16 and kcma-d8), this is why we also
disable crossgcc_ada in the configuration, since it will be built by specific boards
if needed, avoiding double compilation.

This commit updates the coreboot code base from release 4.11 to 4.11_branch for kgpe-d16,
kcma-d8, kfsn4-dre and addresses one new blob related to this update.
The main reason to update the codebase is to prevent a bug with RAM initialization
that occured with coreboot 4.11 and raised the following critical error:
fam15_receiver_enable_training_seed: using seed: 0054

This coreboot revision also correct some bugs with SMM, SMBIOS, IPMI and BMC.
Some new values in coreboot configuration make coreboot first build stop to prompt
users and forcing them to choose an option to continue:
- CONFIG_STM
- CONFIG_DEBUG_IPMI
- CONFIG_VENDOR_VIA
- CONFIG_SOUTHBRIDGE_AMD_CIMX_SB900
- CONFIG_IPMI_FRU_SINGLE_RW_SZ
- CONFIG_IPMI_KCS_TIMEOUT_MS
A bug has been opened about CONFIG_STM on our bug tracker [1], and we decided,
for now, to unset this option explicitely.
So in this commit we just regenerated configurations for each fam15h board via
coreboot build prompts and copied the resulting configurations in the configuration
folder and that results in the following:
- unset CONFIG_STM
- unset CONFIG_DEBUG_IPMI
- unset CONFIG_VENDOR_VIA
- unset CONFIG_SOUTHBRIDGE_AMD_CIMX_SB900
- set CONFIG_IPMI_FRU_SINGLE_RW_SZ=16
- set CONFIG_IPMI_KCS_TIMEOUT_MS=5000

being treated as errors
- removing a redundant definition of AcpiGbl_DbOpt_NoRegionSupport

With newer hostcc, trying to build GCC 8.3.0 will raise an error from ld:
undefined reference to `__gnat_begin_handler_v1'
This commit adds a patch for GCC found on coreboot [1] correcting this
error by backporting the GNAT exception handler v1 to GCC 8.3.0 allowing
GNAT to be built with newer hostcc like GCC 10+.

we have a build failure:

guix build --source, we recovered these files and published it at the addresses

with this change, it's unlikely we'll hit errors again. previously,
some projects used were calling "python" which in context was
python3, but on some setups, the user only has python2 and python3
but no symlink for "python" (which if exists, we assumed linked to
python3)
now it's unambiguous. docs/build/ can probably be updated now, as
a result of this change, to remove the advice about that
Coreboot is enabling PECI on these CPUs which, according to Intel erratum, must
only be done after loading microcode updates, otherwise the CPUID feature set
becomes corrupted. That's my understanding, and I think this is why SpeedStep
is broken. To be specific, it could but but operating systems no longer detect
that the feature is supported. In any case, belgin on IRC found the commit in
coreboot, after a bisect, enabling PECI. This commit in Libreboot adds a patch,
reverting coreboot's PECI patch.
tianocore is a liability for the libreboot project. it's a bloated mess, and
unreliable, broken on many boards, and basically impossible to audit.
i don't trust tianocore, so i'm removing it.
4mb and 8mb users can just pad their roms to 16mb, using the instructions on
<https://libreboot.org/faq.html#how-do-i-pad-a-rom-before-flashing>
maintaining them in lbmk is a waste of time, and also a hazard because it's a
lot of duplicated labour when making any changes, which could result in awful
mistakes being made
mitigate missing characters in unifont for border/arrow characters. this saves
space because now it is no longer necessary to add a custom font
the background added has the libreboot logo on it, and it's 10kb in size unlike
the old gnulove background that was hundreds of KB
These option ROMs are known to cause a system hang. If you insert an empty
option ROM into CBFS, it disables any option ROM loading for those devices
when using SeaBIOS.
This fixes issue 3:
https://notabug.org/libreboot/lbmk/issues/3
In this issue, GM45 laptops such as X200/T400 will hang on reboot (normal boot
works, and shutting down works too).
2MiB and 16MiB were the only flash sizes supported. 4 and 8MiB have been
added.
Now there are only libgfxinit_txtmode configs.
Use seabios_withgrub or seabios_grubfirst ROMs if you wish to use an add-on
GPU.
this is forked from the "libre" branch in osboot, which is itself a libre,
