Leah Rowe ed0678ae2e haswell: only provide NRI-based ROMs in 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.

Leah Rowe 0693349133 coreboot/dell9020mt: disable pcie rebar
i enabled it but it's buggy according to comments on gerrit.

off, when i had this tested.

Leah Rowe 91792c0c33 update coreboot configs
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.

Leah Rowe dfad11f350 NEW BOARD: Dell OptiPlex 9020 MT (and 7020 MT)
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.
