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.

the current entry is fine, but it would then not support
other configs of different flash sizes, unless they are

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
at the diff of this commit as an example.

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

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.

in some cases, the build system was needlessly, and sometimes
erroneously, creating crossgcc symlinks, which then caused an
issue, namely:
in lbmk release builds, dell e6400 is build before fam15h boards,
and it sets xtree, but fam15h_rdimm doesn't, and later this would
cause fam15h_rdimm boards to use xtree="default" (because they don't
set xtree), causing the newer toolchain to be used on coreboot 4.11.
this patch fixes the issue. quite a simple problem, actually.

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).
