at present, the inject scripts compress refcode in a way
that is not reproducible, so there's no way to verify
that the firmware is correct, via checksum verification,
when injecting vendor code on release images
the lack of reproducibility in recompression will have to be
addressed, but the issue is that lbmk does not provide its own
sources for compression utilities, instead opting to use the
system's own compression utility
so the solution might be for lbmk not to use the host's utility,
and compile its own, or insert the refcode uncompressed. for now,
simply disable the hp 820 g2 target in libreboot releases
this uses the same logic recently implemented for excluding
mrc-based haswell images in libreboot releases

release="n" is set in target.cfg on haswell build targets
that use mrc.bin
script/update/release exports LBMK_RELEASE="y"
script/build/roms skips building a given target if release="n"
in target.cfg *and* LBMK_RELEASE="y"
you could also do the export yourself before running ./build roms,
for example:
export LBMK_RELEASE="y"
./build roms all
This would skip these ROM images. The native haswell raminit is
now stable enough in my testing, that I wish to delete the MRC-based
targets. This is in line with Libreboot's Binary Blob Reduction Policy,
which states: if a blob can be avoided, it should be avoided.
The problem is that users often run the inject script in *lbmk* from
Git, instead of from the src release archive. I forsee some users
running this on modern lbmk with older release images. If the mrc-based
target isn't there, the user may use an NRI-based target name, and
think it works; they will insert without MRC. I foresaw this ages
ago, which is why Caleb and I ensured that the script checks hashes,
and hashes are included in releases.
Therefore: for the time being, keep the MRC-based configs in lbmk
but do not include images for them in releases. This can be done
indefinitely, but I'll probably remove those configs entirely at
some point.
On the following boards, Libreboot now will *only* provide NRI-based
ROM images for the following machines:
* Dell OptiPlex 9020 SFF
* Dell OptiPlex 9020 MT
* Lenovo ThinkPad T440p
* Lenovo ThinkPad W541/W540
I now recommend exclusive use of NRI-based images, on Haswell
hardware. It's stable enough in my testing, and now supports S3.

sff happened to work, but mt would not boot with the patch,
because it called die() on unknown chassis type, and the gpio
happened to have a bad value in the old patch, because it wasn't
reading the right gpio.
i tested the fix on the old patch, but then decided to use
mate's new patch because instead of calling die(), it simply
boots with fan control disabled (max fan speed in that case),
if this happens again.
mt and sff have both been tested with this new version of the
patch. both of them boot, and they both have proper fan control.

what i've merged is patchset 4. i had to rebase it slightly,
because the libreboot version has the iommu toggle on cmos
configs, which are files that mate's patch also changes,
leading to merge conflict.

the grub payload was previously disabled, because the libre
mrc code sets up xhci rather than ehci, and grub did not have
xhci support (not natively).
libreboot now has xhci support in the grub payload, so enable
grub on these configurations.

broadwell mrc enables both igpu and dgpu to be enabled
at any given time. if the onboard (intel) gpu is set as
primary, the logic to disable it is not executed within
coreboot; instead, the igpu is used for vga decode.
on some t440p/w541 thinkpads, both an intel and nvidia
gpu are present. in this setup, the intel gpu must be
used for vga, and all output, but rendering can be
offloaded to the nvidia gpu (nvidia optimus).
optimus would never work on haswell mrc.bin, because it
always disables the igpu when a dgpu is present, so a hack
exists in coreboot that hides the dgpu from mrc, so that the
igpu remains enabled. broadwell mrc doesn't do this, so the
option to hide PEG devices has been disabled in these
configs.
the broadwell mrc has better peg device handling, and can
support 16gb modules on broadwell hardware; it may well
support these modules on haswell hardware too, though ddr3
sodimms are very hard to find (and expensive). (and currently
untested, with this patch)

broadwell mrc has better peg handling and can support 16gb
modules on broadwell machines - the blob can be used on haswell
machines too, instead of haswell mrc, and it might support 16gb
modules on these machines (not yet tested, but using broadwell
mrc does at least boot as reliably as haswell mrc anyway)
one little quirk with haswell mrc is that it actually handles
vga decode, disabling the igpu entirely, when a dgpu is used.
the broadwell mrc enables both GPUs and does not handle vga
decoding, so we must handle this the usual way; my patch for
this was merged upstream and i'm also adding it to libreboot,
which currently uses an older coreboot revision. this is needed
for dgpu to work. see patch:
0040-nb-haswell-Disable-iGPU-when-dGPU-is-used.patch
broadwell mrc may also make dealing with nvidia optimus setups
more reliable, on laptops that have nvidia GPUs, but this patch
does not add bmrc configs for t440p/w541
NOTE: on t440p/w541 laptops with nvidia graphics, the video output
is wired to intel but rendering can be offloaded to nvidia. in this
setup, we want vga decode to be done on intel, so i've set these
configs to enable CONFIG_ONBOARD_VGA_IS_PRIMARY (set it to y)

see:
https://github.com/9elements/grub/commits/xhci-module-upstreaming-squash_v4/
grub only supports xhci on bios/uefi targets, but not coreboot.
some newer machines don't have ps/2 controllers, and boot in a
way where ehci isn't available at startup; the controller can't
be used by ehci code, there must be xhci support.
the code is from Patrick Rudolph working on behalf of 9elements.
the code was also sent here for review:
https://lists.gnu.org/archive/html/grub-devel/2020-12/msg00111.html
however, upstream never merged these patches. libreboot will have
to maintain these from now on. the patches have been rebased for
use with grub 2.12.

Needed to make graphics cards work. Turn it on if you're using
only the Intel GPU.
With IOMMU *enabled*, graphics cards do not work reliably at all.
The cause still needs to be investigated, but the symptoms are
graphical corruption on the screen, and Xorg usually crashes.
In some cases (on some cards), TTYs can still be used; the payload
can still be used reliably, on a graphics card, but Xorg fails to
work properly.
This could be a bug in Linux drivers, instead of anything that
coreboot does (not yet tested in factory BIOS).
Leaving it off by default will ensure reliable operation on all
setups, whether an iGPU or dGPU is used.

It is now possible to disable the IOMMU on Haswell
boards, by doing this on your ROM image:
./nvramtool -C libreboot.rom -w iommu=Disable
To enable it again, do this:
./nvramtool -C libreboot.rom -w iommu=Enable
If not specified, the default behaviour is *on*.
A follow-up patch will turn IOMMU *off* by default,
on Dell OptiPlex 9020 SFF/MT, by setting it as such
in cmos.default. This is to make graphics cards work
properly to work around a bug when it's turned on.
Leaving the IOMMU enabled is recommended, if it works.
It works in most cases, including on 9020 SFF/MT when
using the Intel GPU without a graphics card inserted.

this was done automatically by running:
./update trees -u coreboot
this has to be done when adding patches for now board ports,
because of the way lbmk and also coreboot's build systems work.
the configs just have to be re-generated to include a line
that says the entry for the newly added boards isn't set. look

on a dgpu setup, igpu was still in use, when tested
by a user. do separate roms that don't enable anything
vga in coreboot, relying instead only on seabios to
execute a vga rom. these roms will only work if you
have a graphics card.

Specifically the MT versions. The SFF versions will
be added separately, in a later commit.
See: https://review.coreboot.org/c/coreboot/+/55232
This patch has been added, from patchset 31. It still
has some unresolved issues, on that patchset, but
it should boot. See commit message there.
Of note: I've enabled PCI REBAR, though it's unknown
whether it will work (some comments there about it though,
on that gerrit page).
I've also set CBFS size to 8MB, not the full size of
the BIOS region; this is required on the T440p which
uses the same mrc.bin file, to get S3 working.
TSEG stage cache disabled, as on other Haswell boards.
The setup: SeaBIOS-only as first payload, but with GRUB
enabled as secondary payload. The _grubonly setup has
been enabled here. This way, the config will work on
iGPU and dGPU setups without issue.

coreboot gerrit patch 55232, patchset 31
the actual board will be enabled in a follow-up patch.
merging the patch on its own first is better practise,
to run ./update trees -u coreboot
this way, there won't be a revision that breaks builds,
due to the idiosyncratic nature of coreboot configuration.

Riku introduced three new patches:
* Add support for multiple chip selects. This allows you to
control multiple chips from the same clip, on systems with
dual flash setups, at least theoretically.
* Enable pull-up on unused chip selects - pull them high so
that chips you connect that to are deactivated while flashing
the target chip. This could be used on thinkpad W541 for
instance, where miso/mosi have 0ohm between them via the two
flash ICs. You could pull the other chip select high.
* Documentation for the above, in the pico-serprog readme.
This goes in tandem with a patch from Riku, present in the
recently integrated flashprog project, namely:
commit ddb6d926783d4f9cbee04c7392718ed8f89daa0e
Author: Riku Viitanen <riku.viitanen@protonmail.com>
Date: Mon Jan 15 19:15:49 2024 +0200
serprog: Add support for multiple SPI chip selects
This functionality will therefore be present in the next
release of Libreboot.

Nico Huber is the rightful project lead. I do not support
the coup that occured within the flashrom project. Nico
has always been of great service to the Libreboot project,
by virtue of his work on both coreboot and flashrom.
Nico Huber was unfairly removed from the flashrom project
infrastructure, due to unfounded accusations hurled at him
by flashrom's new project lead. The accusations are unfounded
because no evidence was given.
Use Nico Huber's fork, named flashprog. We will work with
flashprog from now on.
