This uses the excellent deguard utility, written by
the excellent Mate Kukri.
A few bugs but it mostly works. Documentation to come
shortly, in lbwww.git.

also bring the coreboot/next modules in line with
the recent merge that did away with coreboot/dell7
the submodules for coreboot/haswell were still there,
and have now been deleted; the haswell tree was used
for the NRI patches, which were moved to /default some
time ago

The fsp module is unnecessary on coreboot/default, and
therefore constitutes a waste of disk space.

Specifically, use the same revision that Mate used in patchset 15.
This will ensure that any issues are *not* caused by the coreboot
revision; this is being done, because the old coreboot revision was
from July, but patchset 15 from Mate is based on a September revision
of coreboot.
I've been eliminating as many variables as possible, trying to fix
SeaBIOS payload on this machine, because it hangs in Libreboot, but
not when building from gerrit directly, which means the coreboot
revision may be a factor (since I'm using his patches on an older
revision so upstream might have made some changes since then that
the port relies on).
For this, a new coreboot tree is used, called "dell7", referring to
the fact that Kabylake is Intel's 7th generation.

This is using Mate Kukri's port, which was added in
previous lbmk revisions. I've added an IFD that sets
the HAP bit, and unlocks regions as standard.
vcfg is set to 3050micro, which defines downloading
of the MEv11 image and it will run deguard automatically.
I made a small adjustment to vendor.sh, because the hotpatch
logic for deguard uses -C in git, and when doing that, the
specified directory path is relative to that Git repository;
the .patch path has been adjusted accordingly.
Also add 3rdparty/fsp to coreboot/default modules.
This board requires the ifdtool option: -p sklkbl
The -p option tells flashrom what quirks are present in a
given IFD. We don't normally need this on other Libreboot
targets that we currently support. The -p option was needed
for creating this modified IFD, and it is therefore needed in
the inject script. Therefore, an "IFD_platform" option is
specified in a given board's target.cfg file. If this is set,
another variable is set that makes -p be used.
In this case, 3050's target.cfg says:
IFD_platform="sklkbl"
This option enables quirks for skylake/kabylake descriptors,
as required when using ifdtool.

it is identical to fam15h_rdimm, with _udimm now removed;
the latter had a patch that added certain behaviour only
intended for rdimm, but the patch in question breaks various
configurations.
raminit has always been unreliable on these boards. i'd rather
simplify it all, in lbmk. i'll probably update this to the dasharo
tree later on, specificalyl for kgpe-d16

The libgfxinit patch and other patches e.g. DDR2 fix, are
now provided in coreboot/default. The Latitude E6400 is now
using the newer coreboot revision from late July 2024.
Some other configs had to change because of this, relating to
the new way that Nicholas handles timing on LVDS displays
with the E6400 port; a default 96MHz clock is still used for
pixel reference clock, overridden with a value of 100MHz on
other GM45 machines, where 96MHz was previously hardcoded.

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

don't use the macports mirror, because it's not certain
whether those tarballs will always be there. use the
coreboot one as a backup instead, and nasm.us as main

support redundant downloads, and enable inclusion of these
tarballs inside release archives, for offline builds.

when we download coreboot, we currently don't have a way to
download crossgcc tarballs, so we rely on coreboot to do it,
which means running the coreboot build system to do it; which
means we don't get them in release archives, unless we add
very hacky logic (which did exist and was removed).
the problem with coreboot's build system is that it does not
define backup links for each given tarball, instead relying
on gnu.org exclusively, which seems OK at first because the
gnu.org links actually return an HTTP 302 response leading
to a random mirror, HOWEVER:
the gnu.org 302 redirect often fails, and the download fails,
causing an error. a mitigation for this has been to patch the
coreboot build system to download directly from a single mirror
that is reliable (in our case mirrorservice.org).
while this mitigation mostly works, it's not redundant; the
kent mirror is occasionally down too, and again we still have
the problem of not being able to cleanly provide crossgcc
tarballs inside release archives.
do it in config/submodules, like so:
module.list shall say the relative path of a given file,
once downloaded, relative to the given source tree.
module.cfg shall be re-used, in the same way as for git
submodules, but:
subfile="url"
subfile_bkup="backup url"
do this, instead of:
subrepo="url"
subrepo_bkup="backup url"
example entries in module.list:
util/crossgcc/tarballs/binutils-2.41.tar.xz
util/crossgcc/tarballs/gcc-13.2.0.tar.xz
util/crossgcc/tarballs/gmp-6.3.0.tar.xz
util/crossgcc/tarballs/mpc-1.3.1.tar.gz
util/crossgcc/tarballs/mpfr-4.2.1.tar.xz
util/crossgcc/tarballs/nasm-2.16.01.tar.bz2
util/crossgcc/tarballs/R06_28_23.tar.gz
the "subrev" variable (in module.cfg) has been renamed
to "subhash", so that this makes sense, and that name is
common to both subfile/subrepo.
the download logic from the vendor scripts has been re-used
for this purpose, and it verifies files using sha512sum.
therefore:
when specifying subrepo(git submodule), subhash will still
be a sha1 checksum, but:
when specifying subfile(file, e.g. tarball), subhash will
be a sha512 checksum
the logic for both (subrepo and subfile) is unified, and
has this rule:
subrepo* and subfile* must never *both* be declared.
the actual configuration of coreboot crossgcc tarballs
will be done in a follow-up commit. this commit simply
modifies the code to accomodate this.
over time, this feature could be used for many other files
within source trees, and could perhaps be expanded to allow
extracting source tarballs in leiu of git repositories, but
the latter is not yet required and thus not implemented.

this is using the same functionality that was added a few
commits ago, to override the use of "git submodule update"
each coreboot submodule has two repositories defined, with
the second one kicking in if the mail one fails upon cloning.

module.list files in the corresponding directories
under config/submodule/, per each coreboot tree.

firstly, memtest86+ is currently not cross compiled and
relies on 64-bit headers (x86_64 only). a 32-bit distro
is unlikely to be able to build 64-bit binaries.
secondly: vboot throws a build error due to -Werror when
building on 32-bit hosts. we rely on vboot code to build
cbfstool, so turn off -Werror on vboot
that's all. 32-bit hosts are not recommended; it is assumed
that you are building on an x86_64 host. work will go into
the build system at a later date to make it more portable,
by cross compiling everything, but this should fix 32-bit
for now.
there are some x60/t60 users who still want to build roms,
so let's allow them that possibility.

The E6400 uses a 100 MHz reference clock on DPLL_REF_SSCLK, whereas
libgfxinit assumed that the reference was always 96 MHz. The frequency
difference caused by a 100 MHz reference with PLL config values
calculated assuming a 96 MHz reference were not significant enough to
cause noticable issues with the more common 1280 x 800 panels, but are
enough to matter for the 1440 x 900 panels which use a higher pixel
clock. This only affected the pre-OS graphics environment provided by
libgfxinit, as Linux drivers would determine the reference clock
frequency based on data in the VBT.
Fix this by making the reference clock frequency in libgfxinit
configurable for GM45 based on a new coreboot Kconfig, which is set to
100 MHz for the E6400.

for single-tree project (e.g. flashprog):
config/submodule/PROJECT/MODNAME/patches
for multi-tree project (e.g. coreboot):
config/submodule/PROJECT/TREE/MODNAME/patches
MODNAME is e.g.:
3rdparty/vboot directory in coreboot: would become vboot
(the submodule codepath is filtered to up to the final slash)
another example:
submodire src dir 3rdparty/foo/bar
MODNAME would be "bar"
Add whatever patches you like to a given submodule.
An example patch is included in this commit.
