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

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.

merging the patch on its own first is better practise,
to run ./update trees -u coreboot

CONFIG_PS2M_EISAID. this is a a string used for the
identifier on the mouse, in ACPI.
CONFIG_PS2K_EISAID this is used for the keyboard.
IASL comes back with this build error:
dsdt.asl 1884: Name(_HID, EISAID("DLLK0534"))
Error 6045 - ^ EISAID string must be of the form "UUUXXXX" (3 uppercase, 4 hex digits) (DLLK0534)
Change DLLK0534 back to PNP0303 and
change DLL0534 back to PNP0F13. These are generic identifiers
for PS/2 keyboard and mouse. Any generic driver will work with
the onboard mouse/keyboard on these machines. They do not need
to be changed. These are the default values anyway. Just leave
them explicitly defined to the default values, for now; if these
options are not set, coreboot will default to these values.
This shouldn't break anything for the users. I've reported this
to Nicholas Chin, author of those patches. Libreboot imported
the new versions of E6430/E6530 board patches in the coreboot
revision update, but the new (technically correct) values broke
IASL, so I've decided to use the old values for now.

Of note:
Several out-of-tree ports have been adjusted to use the new SPD config
style, where it is defined in devicetree. I manually updated the E6530
patch myself, based on the update that Nicholas did on E6430 (Nicholas
will later update the E6530 patch himself, and I'll re-merge the patch).
Several upstream patches now exist in this revision, that we were able
to remove from lbmk.
The heap size patch was reverted upstream, as we did, but see:
https://review.coreboot.org/c/coreboot/+/80023https://review.coreboot.org/c/coreboot/+/79525
Although we still disable the TSEG Stage Cache, ivy/sandy/haswell should
be reliable on S3 now (leaving TSEG Stage Cache disabled, for now, anyway).

with neutered ME, fan control fails. while there are
ways to mitigate it, many users will not, and will
likely see their system overheat, which is very
dangerous.
this bug (failed fan control on neutered ME) only
affects arrandale machines such as lenovo x201.
the newer machines are not affected by this.
other arrandale machines will probably not be added
to libreboot because of this, or they will be subject
to further testing.

This is of Broadwell platform, one generation above Haswell.
Of note: this uses HP Sure Start. Although the flash is 16MB,
our CBFS section (and IFD configuration) assumes 12MB flash,
so the final 4MB will be left unflashed on installation,
after blanking the private flash. The coreboot documents have
more information about this.
Some minor design changes in lbmk were made, to accomodate
this port:
Support for extracting refcode binaries added (pulled from
Google recovery images). The refcode file is an ELF that
initialises the MRC and the PCH. It is also responsible for
enabling or disabling the Intel GbE device, where Google
does not enable it, but lbmk modifies it per the instructions
on the coreboot documentation, so as to enable Intel GbE.
Google's recovery image stores the refcode as a stage file,
but coreboot changed the format (for CBFS files) after 4.13
so coreboot 4.13's cbfstool is used to extract refcode. This
realisation made me also change the script logic to use a
cbfstool and ifdtool version matching the coreboot tree, for
all parts of lbmk, whereas lbmk previously used only the
default tree for cbfstool/ifdtool, on insertion and deletion
of vendor files - it was 81dc20e744 that broke extraction of
refcode on google's recovery images, where google used an older
version of cbfstool to insert the files in their coreboot ROMs.
A further backported patch has been added, copying coreboot
revision f22f408956 which is a build fix from Nico Huber.
Iru Cai submitted an ACPI bugfix after the revision lbmk
currently uses, for coreboot/default, and this fix is
needed for rebooting to work on Linux 6.1 or higher. This
patch has been backported to lbmk, while it still uses the
same October 2023 revision of coreboot.
Broadwell MRC is inserted at the same offset as Haswell,
so I didn't need to tweak that.

arch no longer needs to be set, on multi-tree projects,
and it has been renamed to xarch
the new behaviour is: if xarch is set, treat it as a
list of crossgcc targets and go through the list. set
the first one as the target, for what lbmk builds, but
build all of the defined crossgccc targets
crossgcc_ada is now xlang, and defines which languages
to build, rather than whether to build gcc-gnat

i had to run make-oldconfig on all of them, because
of the port that riku added the other day. lbmk doesn't
use defconfigs, it uses full configs, so we have to
make sure they're kept in sync
this patch is the result of running the following command
in a fresh clone of lbmk:
./update trees -u coreboot
i should probably switch to defconfigs.

the e6400_4mb target has libgfxinit and (if seabios) vgarom
initialisation, but has issues on the nvidia model, even when
using nomodeset. with this target, e6400nvidia_4mb, only
the vgarom initialisation is used, libgfxinit is disabled.
on nvidia models, this one should work a little bit better.
specifically: nouveau crashes on this machine, with libreboot
installed, but you can use nomodeset. however, when libgfxinit
is also enabled, nomodeset no longer works properly.
so this target disables all video initialisation in coreboot.
only seabios will initialise anything video-related, by
executing the vga option rom.

at present, lbmk can remove microcode updates on images for
a given target, if the target specifies
microcode_required="n" in target.cfg
lbmk then provides images with microcode, and images without,
in a given release. although the user can also remove them
manually, this just makes it a bit more convenient, for those
users who do wish to run without the updates. this functionality
is provided only on those platforms where no-microcode is tested.
well, this behaviour implements a compromise on libreboot policy,
which is to always include microcode updates by default. see:
Binary Blob Reduction Policy
the *canoeboot* project now exists, developed in parallel with
libreboot, and it ships without microcode updates, on the same
targets where lbmk also handled this.
running without microcode updates is foolish, and should not
be encouraged. clean up lbmk by not providing this kludge.
the libreboot documentation will be updated, telling such users
to try canoeboot instead, or to remove the update from a given
libreboot rom - this is still possible, and mitigations such as
PECI disablement on GM45 are still in place (and will be kept),
so that this continues to work well.

only call crossgcc for coreboot and u-boot, but use
hostcc for everything else. simplify the checking of
which architecture to compile for. "arch" in target.cfg
files has been modified, to allow further simplification.
without this patch, the logic currently only *barely* avoids
using crossgcc on things like utils, and only works in practise
because, in practise, lbmk only works on x86_64 anyway.
the new logic, as per this patch, is simpler and more robust.

Fix a few issues with the E6430 configs to make it consistent with
configs for other boards and function as intended.
- Add VBT to CBFS: Although the VBT was enabled at the board level
Kconfig in a previous commit (CONFIG_INTEL_GMA_HAVE_VBT), the config
to actually add the VBT to CBFS was still unset.
- Enable the static option table: The old config would always use the
fallback values hard coded in the coreboot tree, rather than the
settings in the cmos.default file
- Enable DRAM clear on boot: This was not set previously, even though
most other boards set this for security.
