Leah Rowe fdbdf0449b Re-enable U-Boot x86 on real mainboards
The previous stability issues were resolved, thanks to
the previous revision which added a fix courtesy Simon Glass.

Leah Rowe eba73c778a Disable U-Boot x86 except on Qemu
It's really buggy on hardware. Disable for now.

I've contacted Simon Glass on IRC, asking about hardware.

Leah Rowe dbe24b039d coreboot/default: Update to 97bc693ab (2024-07-29)
Several patches are now merged upstream and no longer needed
in lbmk, such as the HP EliteBook 8560w patch, and related
patches. Some patches were changed, for example the Dell Latitude
ivb/snb laptops are now variants in coreboot, instead of being
individual ports; now they re-use the same base code.

This this, the corresponding files under config/submodules
have changed, for things like 3rdparty submodules e.g. libgfxinit,
and tarballs e.g. crossgcc.

This is long overdue, and will enable more boards to be added.
This newer revision will be used in the next release, and some
follow-up patches will merge these trees into default:

* coreboot/haswell
* coreboot/dell

Leah Rowe e67cd17164 roms: only support SeaBIOS/SeaGRUB on x86
Never, ever build images where GRUB is the primary payload.

These options have been removed from target.cfg handling:

* seabios_withgrub
* grub_withseabios

The "payload_grub" variable now does the same thing as
the old "seabios_withgrub" variable, if set.

The "grubonly" configuration is retained, and enabled by
default when SeaGRUB is enabled (non-grubonly also available).

Due to lbmk issue #216, it is no longer Libreboot policy to
make GRUB the primary payload on any board. GRUB's sheer size
and complexity, plus the large number of memory corruption issues
similar to it that *have* been fixed over the years, tells me
that GRUB is a liability when it is the primary payload.

SeaBIOS is a much safer payload to run as primary, on x86, due
to its smaller size and much more conservative development; it
is simply far less likely to break.

If GRUB breaks in the future, the user's machine is not
bricked. This is because SeaBIOS is the default payload.

Since I no longer wish to ever provide GRUB as a primary
payload, supporting it in lbmk adds needless bloat that
will later probably break anyway due to lack of testing,
so let's just assume SeaGRUB in all cases where the user
wants to use a GRUB payload.

You can mitigate potential security issues with SeaBIOS
by disabling option ROM execution, which can be done at
runtime by inserting integers into CBFS. The SeaBIOS
documentation says how to do this.

Libreboot's GRUB hardening guide still says how to add
a bootorder file in CBFS, making SeaBIOS only load GRUB
from CBFS, and nothing else. This, combined with the
disablement of option ROM execution (if using Intel
graphics), pretty much provides the same security benefits
as GRUB-as-primary, for example when setting a GRUB password
and GPG checks, with encrypted /boot as in the hardening guide.

Leah Rowe fc7ae3e590 lib.sh: more unified config handling
replace it with logic that simply uses "." to load
files directly. for this, "vcfg" is added as a variable
in coreboot target.cfg files, referring to a directory
in config/vendor/ containing a file named pkg.cfg, and
this file then contains the same variables as the
erstwhile config/vendor/sources

config/git files are now directories, also containing
pkg.cfg files each with the same variables as before,
such as repository link and commit hash

this change results in a noticeable reduction in code
complexity within the build system.

unified reading of config files: new function setcfg()
added to lib.sh

setcfg checks if a config exists. if a 2nd argument is
passed, it is used as a return value for eval, otherwise
a string calling err is passed. setcfg output is passed
through eval, to set strings based on config; eval must
be used, so that the variables are set within the same
scope, otherwise they'd be set within setcfg which could
lead to some whacky results.

there's still a bit more more to do, but this single change
results in a substantial reduction in code complexity.

Leah Rowe 893e88bc81 roms: don't insert timeout.cfg
this is bloat, because it's something the user can already
do at runtime configuration anyway.

set it to a reasonable default of 8 seconds instead of 5,
and don't honour the timeout variable in target.cfg.

this will be documented in the next release.

Leah Rowe 0b37653ab9 grub: only enable nvme if needed on a board
remove nvme support from the "default" grub tree

now there are three trees:

* default: no xhci or nvme patches
* nvme: contains nvme support
* xhci: contains xhci and nvme support

this is in case a bug like lbmk issue #216 ever occurs
again, as referenced before during lbmk audit 5

there is no indication that the nvme patch causes any
issues, but after previous experience i want to be sure

Leah Rowe 05fbd39298 remove all status checks. only handle release.
the release variable is all we need, turning a target on
or off for a given release.

the status checks were prone to bugs, and unnecessary; it
also broke certain benchmark scripts.

it's better to keep the lbmk logic simpler. board status
will be moved to the documentation instead.

Leah Rowe ce7fd754a3 build/roms: report status when building images
export LBMK_VERSION_TYPE=x
x can be: stable, unstable

in target.cfg files, specify:
status=x
x can be: stable, unstable, broken, untested
if unset, lbmk defaults to "unknown"

if LBMK_VERSION_TYPE is set, no confirmation is asked
if the given target matches what's set (but what's set
in that environmental variable can only be stable or
unstable)

if LBMK_RELEASE="y", no confirmation is asked, unless
the target is something other than stable/unstable

"unstable" means it works, but has a few non-breaking
bugs, e.g. broken s3 on dell e6400

whereas, if raminit regularly fails or it is so absolutely
unreliable as to be unusable, then the board should be
declared "broken"

untested means: it has not been tested

With this change, it should now be easier to track whether
a given board is tested, in preparation for releases. When
working on trees/boards, status can be set for targets.

Also: in the board directory, you can add a "warn.txt" file
which will display a message. For example, if a board has a
particular quirk to watch out for, write that there. The message
will be printed during the build process, to stdout.

If status is anything *other* than stable, or it is unstable
but LBMK_VERSION_TYPE is not set to "unstable", and not building
a release, a confirmation is passed.

If the board is not specified as stable or unstable, during
a release build, the build is skipped and the ROM is not
provided in that release; this is in *addition* to
release="n" or release="y" that can be set in target.cfg,
which will skip the release build for that target if "n"

Base revision changed to:

commit b6cbfa977f63d57d5d6b9e9f7c1cef30162f575a

    mb/google/dedede/var/metaknight:Add fw_config probe for multi codec
    and amplifier

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/+/80023
https://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).

Also included in upstream now:

Leah Rowe eff9130b7a update/trees: further simplify crossgcc handling
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
