previously, "normal" initmode relied on the vgarom-based
seabios config, which enables option roms, but then lbmk
would insert pci-optionrom-exec 0 for vgarom, and 2 for normal
in libreboot, coreboot roms with "vgarom" in the filename do
pci option rom execution from coreboot, and "normal" roms
do execution from seabios(where seabios is the only payload
provided on normal setups)
this is because payloads like grub can also be used, on vgarom
setups, where coreboot must handle oprom execution
the deleted patch (in this commit) was written to fix an

This reverts commit fe2b72035f.
The GRUB patch to fix the E6400 broke other systems and has been
reverted. As a result, GRUB needs to be disabled again on the E6400
until a better fix has been created.
This introduces a patch to grub which disables the coreboot
specific handling, allowing PS/2 keyboards to be handled the
same as i386-pc. However this alone breaks the keyboard in
Linux, requiring coreboot to perform PS/2 initialization.
I think GRUB may be restoring the original configuration of
the PS/2 controller once it exits, and if coreboot doesn't
initialize the controller then it's restored to the default
state which Linux doesn't seem to like. I think the emulated
keyboard interface provided by the EC on the E6400 behaves
in a non-standard way that is incompatible with the old
coreboot specific handling.
ps/2 internal keyboard faulty in grub target
i386-coreboot, according to nic3-14159
normal i386-pc grub (bios grub) is fine,
booted from seabios
it is being investigated
Tested the 4MiB ROMs but not the 8 or 16 MiB ones. This uses the same
board.cfg as the GM45 ThinkPads with an IFD+GBE from ich9gen.
Known issues:
- The internal keyboard does not work properly in GRUB. It seems like
the keyboard controller is outputing set 1 (XT) scancodes, but GRUB
is interpreting them as set 2 (AT) scancodes. This may also have
something to do with scancode translation. However, the keyboard works
fine in SeaBIOS and Linux. USB keyboards also work properly.
- The subsystem IDs in the GBE region are hardcoded for a Thinkpad in
ich9gen, though this doesn't seem to cause issues in Linux. The vendor
IFD and GBE region do have some differences from the generated
binaries, though they do not appear to be critical.
libreboot will still include microcode updates
by default, but mitigations against broken speedstep
and reboot (when microcode updates are excluded) were
removed following the merge with osboot
this patch restores those mitigations; the patch
reverts coreboot to older smrr code (which works fine, it
isn't critical to use the new behaviour) and disables peci
(pointless feature)
i'll probably re-tool this later to apply the changes
conditionally to whether ucode is present
this is not a change in policy. policy says:
include cpu microcode updates by default
policy also says:
libreboot must be configurable
microcode removal via cbfstool remove -n, counts as
configuration, and in practise is not possible on
gm45 patches in current libreboot; this patch corrects
that problem, allowing the machines to work somewhat
well (same stability issues as before, like MCE errors
resulting in kernel panic on high CPU/memory usage,
but i digress)
happy... hacking
This is useful for e.g. HP EliteBook 2560p.
In coreboot config, enable e.g. (for lbmk blobutil):
CONFIG_KBC1126_FW1="../../ec/hp2560p/ec.bin.fw1"
CONFIG_KBC1126_FW2="../../ec/hp2560p/ec.bin.fw2"
In resources/blobs/sources you would have these entries:
EC_url
EC_url_bkup
EC_hash
In cases where the vendor update file contains a full
ROM image encompassing IFD+GbE+ME+BIOS, blobutil was
saving the *entire* ROM containing those, as me.bin.
For example, if it's an 8MB ROM, blobutil would create
a me.bin file that is actually the whole ROM containing:
* Vendor IFD region
* Vendor GbE(if it has one)
* Vendor ME region
* Vendor BIOS region
This fix tries with -M and -O first. In this combination,
me_cleaner shall extract me.bin (neutered) and save it.
If that fails, then the normal method with just -O is
tried, which by this logic would always be a lone ME
image if it succeeds.
I tested downloading ME images on existing boards with
this, and it didn't break them, and this fixes the bug.
This is done for HP 8200 SFF which Riku_V is adding to

bl1 bootloader blobs needed, and lbmk doesn't currently
auto-download these for insertion, so their presence in
the build system is problematic because people might build
these and think they work - they don't, due to the lack of
those bl1 blobs
notes about this are included in lbwww, on the compatibility
list. these can be re-added and tested later, when lbmk handles
those bl1 bootloader blobs
u-boot is known broken on these, last revision
known working is 2021.01

Bruteforce it. Some executables are just using inno
archival but some are simple LZMA. This patch handles
both of them, and also the event where you have LZMA
compressed files (even LZMA compressed files within
LZMA compressed archives) within any inno/lzma compressed
executable.
It recursively scans inside a vendor update, to find
a me.bin files for neutering with me_cleaner.
This is in preparation for two new ports in Libreboot:
* HP EliteBook 8560w
* Apple MacBook Air 4,2 (2011)

MRC caches in a certain way, that Heads was able to work
around in their build system, for this board.
I've adapted the relevant config differences, from their project
as of heads revision 96440b928acb06de5b925ea12014c9c280b23165
The downside is that CBFS now has to be 8MB in size. The upside
is that the machine also boots much faster
See:
f0792117efhttps://github.com/osresearch/heads/pull/1282#issuecomment-1400634600
I have not adapted their IFD changes, versus Libreboot, because theirs
simply has a different version string, and uses different read/write
permission bits for regions as defined in the IFD.
This affects:
t440p_12mb_mrc
w541_12mb_mrc
S3 suspend/resume still broken on these targets which use the libre
MRC init (replacement code by Angel Pons, recently merged in lbmk):
t440p_12mb
w541_12mb
With clever use of FMAP, the rest of the BIOS region might still be
used. However, for our purposes, 8MB CBFS will do just fine.
Heads's changes configure MRC so that caching is handled properly,
for when the machine returns from sleep. Setting CBFS to be any
higher will result in slower boot times, and broken S3 resume, due
to MRC cache misalignment (this is based on my understanding, reading
through the Heads project looking at their research on this).
At some point in the future, Angel's libre MRC code will probably
be finished, and merged, with more fine tuning possible to allow
bigger CBFS sizes.
libre mrc on haswell is quite buggy for now, but works in
a limited fashion
this patch re-adds the old configs, but as _mrc for example
t440p_12mb_mrc instead of t440p_12mb
and t440p_12mb (without _mrc) still uses the libre mrc code
i found that with libre mrc, usb was broken in grub
however, it worked nicely in seabios
for our purposes, doing seabios-only roms in text mode
is best for now
i'm going to re-add mrc.bin, but for t440p_12mb_mrc
and w541_12mb_mrc, as new config names. the regular
t440p_12mb and w541_12mb will continue to use libre
mrc, but the _mrc ones will use mrc.bin and retain the
grub payload in board.cfg

this uses the following patch set from gerrit, as yet
unmerged (in coreboot master) on this date:
https://review.coreboot.org/c/coreboot/+/64198/5
logic for downloading mrc blobs has been deleted from
lbmk, as this is now completely obsolete (for haswell
boards)
if other platforms are added later that need mrc.bin,
then logic will be re-added again for that
this fixes the build error:
Error: name not set
Usage: ./download gitmodule [name]
when running:
./download all
running "all" runs all scripts under downloads,
one of which was the gitmodule script itself, therefore
being run without argument
some checks check for specific utils, which are
then used to indicate the existence of other utils,
which means that building them singularly, as is
currently done, may result in errors later if another
tool doesn't exist compiled yet
this is an obscure bug, fixed by this patch. more of a
workaround really. a dirty hack. when checking for any
of the coreboot utilities required, build all coreboot
utilities that are possibly required
the utilities are small enough that this does not add
much extra time to build, and in most cases, all of them
will be needed anyway
U-Boot can be configured via environment variables which can be saved to
various storage devices. This usually defaults to MMC or SPI depending
on where it boots from, but assumes the device's layout is controlled by
U-Boot.
We should store the environment in SPI flash, but we also need to
configure coreboot FMAPs to reserve the area U-Boot would use as its
environment storage. For now, disable environment storage by setting
ENV_IS_NOWHERE=y to avoid overwriting random regions of SPI or MMC if
someone tries to save the variables.

Set default U-Boot revision to v2023.01 and rebase patches on top of
that. Upstream kconfig status is a bit unstable, so updating configs
with `make oldconfig` would miss important upstream changes.
For each board, run `make savedefconfig` and `diffconfig -m` at the old
version to get a diff from upstream defconfigs. Fix those affected by
upstream changes, like SYS_TEXT_BASE being renamed to TEXT_BASE. Then
append those to the new version's defconfigs and run `make olddefconfig`
to get updated configs.

Add a build for QEMU AArch64 virtual machine using U-Boot as payload.
Coreboot config is based on the following defconfig:
CONFIG_CBFS_SIZE=0x00c00000
CONFIG_BOARD_EMULATION_QEMU_AARCH64=y
CONFIG_CONSOLE_CBMEM_BUFFER_SIZE=0x20000
CONFIG_COREBOOT_ROMSIZE_KB_12288=y
CONFIG_UART_PCI_ADDR=0x0
The resulting ROM can be booted with a command line like:
qemu-system-aarch64 \
-machine virt,secure=on,virtualization=on \
-cpu cortex-a53 -m 1G \
-vga none -display none -serial stdio \
-bios bin/qemu_arm64_12mb/uboot_*.rom

Add a U-Boot payload build for the QEMU AArch64 virtual machine. The
config is same as upstream "qemu-arm64" defconfig, but SYS_TEXT_BASE is
set to 0x50000000 so that it doesn't conflict with coreboot. QEMU
auto-generates and passes a device-tree file to U-Boot at runtime,
there's no compile-time canonical version, so there's no need to set
REMAKE_ELF or OF_EMBED.
It's not immediately obvious if QEMU-specific drivers are available to
support display output, but most coreboot integration is unavailable
(depends on x86) and entire video subsystem is disabled in the U-Boot

U-Boot runtime configuration is done with a device-tree file, which is
built alongside the executable in the upstream build system, and must be
available to U-Boot at runtime.
This device-tree is normally not linked into the default "u-boot" ELF
file. So far we have been handling it by re-creating a "u-boot.elf" from
the raw binary parts by setting REMAKE_ELF, and using that as the
coreboot payload. Unfortunately, that fails to build for x86 boards,
more specificly the "coreboot" boards upstream.
It's also possible (but discouraged) to set OF_EMBED to embed the
device-tree file into the U-Boot itself, in which case we could use the
"u-boot" file as the payload on the "coreboot" boards. Add support for
using the "u-boot" file as the payload if "u-boot.elf" doesn't exist.

this is a hangover from pre-osboot-merge libreboot. the idea
was to distribute fsdg uboot archives
lbmk has uboot support, and releases will simply
include uboot in the main src archive like with everything else
the --nuke option in ifdtool will be used instead, to nuke
the ME regions in specific rom sets (and cbfstool will be
used to delete mrc.bin files from rom sets)
the new method being implemented is heavier on disk io, but
simplifies lbmk, and disk io could still be optimised in
the following ways:
* when copying roms from boards with ME in them, use
ifdtool --nuke to get filename.rom.new, and *move* (not copy)
filename.rom.new to the new destination (for use with tar)
* possibly modify ifdtool to make efficient use of mmap for
disk i/o; it currently loads entire roms into an allocated
buffer in memory
New x230edp_12mb target uses the
https://review.coreboot.org/c/coreboot/+/28950 patchset to add an
X230_EDP target to the default coreboot branch.
Consequently the "fhd" coreboot branch is no longer needed and has
been safely removed.
the intended use-case scenario was one in which vga rom initialisation
would be used, on desktop configurations, but without coreboot itself
handling vga rom initialisation, instead leaving that task to seabios
it was assumed that grub, when running on the bare metal with
build option "--with-platform=coreboot" would be able to display
like this, but it is not so when tested
in such setups (add-on gpu with grub payload), it is necessary to
extract the video bios and insert it into the coreboot rom, having
coreboot handle such execution. this is beyond the scope of lbmk,
in context of automated building, because we cannot reliably predict
things such as PCI IDs
do away with this build option entirely, for it does not serve the
intended purpose. it will be necessary to run PC GRUB instead (build
option --with-platform=i386-pc). PC GRUB can still read from CBFS,
and you could provide it as a floppy image file inside CBFS for
SeaBIOS to execute. in this setup, GRUB would function as originally
intended by the seabios_withgrub option; such a configuration is
referred to as "SeaGRUB" by the libreboot project, and experimentation
was done with it in the past, to no avail
it's better to keep things simple, in the libreboot project. simpler

In recent coreboot versions, running distclean started to erase the
cbfstool binary we built earlier in the util/cbfstool dir via the
cbutils build script call. The coreboot build puts it in a different
directory, and the roms build script can't find it when trying to add
payloads to the roms. This doesn't make the script fail (because set -e
is stupid like that), and the build appears to succeed if you don't look
close enough to see the "cbfsutil not found" error.
Build the coreboot utils we want at the places we want them after
calling distclean, so that we can actually use cbfsutil and avoid
silently-broken roms with newer coreboot versions.

This enables embedding U-Boot into the coreboot roms as the payload. For
now, the ELF file generated by enabling CONFIG_REMAKE_ELF is used, which
includes the U-Boot binary and the board-specific device-tree file. It
might be better to use the FIT payload support for U-Boot, but that was
reportedly broken and is not tested yet.
Coreboot boards can specify payload_uboot="y" in their board.cfg to
enable building a rom with U-Boot as the payload, which is built from
the U-Boot board with the same name. Boards can further specify a
uboot_config option, to choose which board-specific config file U-Boot
should be built with.

This enables building U-Boot for boards which have config files in
resources/u-boot, and copying built files that could be usable to make
coreboot payloads. Right now, there is no such board in this repo.
The most important file here is "u-boot.elf", which is a combination of
the U-Boot binary and the appropriate device-tree file for the board.
Building this needs CONFIG_REMAKE_ELF=y on the U-Boot part, and using
this with CONFIG_PAYLOAD_ELF=y on the coreboot build works fine.
Note that this isn't enough to make U-Boot-only releases, since
low-level prerequisites like arm-trusted-firmware aren't passed in to
the U-Boot build system. Coreboot builds its own copy of TF-A and sets
it up on the board, so using these U-Boot builds as payloads should
still work.

Keeping the git repositories is useful while development, e.g. to avoid
git cloning repositories over and over again while debugging download
scripts. Setting the NODELETE environment variable keeps the blobs and
the git repositories. Allow a slightly finer-tuned version of this where

The U-Boot download script is designed to help with releasing
u-boot-libre and it can only prepare a generic U-Boot v2021.07 tree.
However, we will need to build board-specific versions of U-Boot to be
able to use it as a coreboot payload effectively.
As a first step toward that, make the download script prepare per-board
copies of U-Boot v2021.07. Then, add a 'v2021.07' pseudo-board for the
u-boot-libre release script to work on.
