However, merging both scripts together would be less efficient

With this change, it's still possible to have a single
file at config/git/revisions, but this has been scrapped.
Instead, multiple files now exist under config/git/ with
the same modules declared, but the files are separated
logically. List of files under config/git:
* bios_extract
* biosutilities
* coreboot
* flashrom
* grub (gnulib also defined here)
* me_cleaner
* memtest86plus
* seabios
* serprog (multiple projects defined)
* u-boot
* uefitool
The rationale behind this change is simple: in the future,
we will stop relying on build systems within imported
projects for the import of git submodules. Instead, we
will handle them directly in lbmk.
Additionally, a Linux payload is planned for Libreboot, made
easier by the recent audit (script handle/make/config makes
it easy to integrate Linux, and handle cross-compilers for
userland utilities); a "linux" file under config/git/ could
also define rules for each project besides linux, such as
musl libc, busybox and other utilities.

on e6400_4mb, the release build scripts remove nvidia's vga
rom which is used on dgpu models. however, microcode is also
removed in separately copied rom images
the inject script was inserting vgaroms directly into these
no-microcode roms, but the microcode blob is bigger than the
vga rom, and cbfstool inserts into the first available free
spot within cbfs, so it was inserting into the spot where
cpu microcode went. this caused the rom checksum to not match
what was generated during build/release/roms being executed
the only real fix is to guarantee offsets within cbfs for all
files, by recording what offsets were used and then calculating
that during insertion
so this patch is a workaround, but fixes the issue. the workaround
is: don't insert blobs directly on no-microcode roms, instead
insert only on microcode-based roms, then re-copy those roms
and remove microcode in aptly named copies
it's a bit more convoluted, but works perfectly fine.

it doesn't really make sense for them to be under
blobs/ - nominally, they are blobs, but they are
well-understood data files containing config data,
that is easily parsed by tools like ich9show or
ifdtool (and tools like bincfg or nvmutil)
blobs/ has been re-purposed: this directory no longer
exists in lbmk, but it is created (and on .gitignore)
when needed, by blobutil
thus, the blobs/ directory shall only contain vendor
files, and only those files that libreboot scrubs from
releases. therefore, build/release/src can (and has
been) simplified; it currently copies just the ifd and
gbe files from blobs/, selectively, and this logic is
quite error prone, requiring maintenance. now, the
build/release/src script simply copies config/ (which
only ever contains distributable files) and entirely
ignores the blobs/ directory
the blob download script already creates the required
directory, except for the sch5545 download; this is
now fixed
lbmk code size is slightly smaller, due to this patch
Signed-off-by: Leah Rowe <leah@libreboot.org>
This cuts down on build time, and it will allow libreboot
to remove large chunks of code.
these ifd/gbe configs are just binary-encoded config files,
in a format well-understood. they can easily be opened up
and displayed, using ich9show or ifdtool, and manipulated
by these tools; bincfg can generate them from scratch, and
nvmutil can change mac addresses, for example.
so, do this and remove from lbmk the following:
* ich9utils (which contains ich9gen) - not needed anymore
* code in lbmk for handling ich9gen and insertions; the
coreboot build system is now used, for this same purpose,
so remove such code from lbmk
this results in a massive code size reduction (thousands of
lines) in lbmk; smaller when only looking at the build
system, but much larger when you consider that ich9utils
is also removed (about 3k sloc)
Signed-off-by: Leah Rowe <leah@libreboot.org>
a follow-up patch will make use of these, rather than ich9gen,
and ich9gen will be deleted.
these files were in fact generated *by* ich9gen.
coreboot has ifdtool and bincfg, the latter of which can
generate both ifd and gbe files for ich9m. that, and nvmutil
which is part of libreboot, can change gbe mac addresses.
i was going to replace ich9gen with a script that would run
bincfg, ifdtool and nvmutil, to greatly reduce code size,
because ich9gen is about 3k sloc.
however, in practise we would always generate the same ifd
config, and basically only change the mac address if that's
what the user wants; nvmutil can already do that just fine.
so, just include the binaries directly.

The same ROM images that you flash on Intel GPU variants,
are now flashed on Nvidia models. The same ROM will work
on both. If an Intel GPU variant is present, libgfxinit
is used, and the VGA ROM is used if an Nvidia GPU variant;
however, release ROMs will scrub the nvidia option ROM,
so release ROMs will only work on Intel GPUs unless you
run the blobutil inject command.
I decided to no longer have this under WIP, but to put
it in master. The issue with it pertains to video drivers,
which is not Libreboot's problem.
Nouveau crashes under Linux, so use "nomodeset" if it does.
The "nv" drivers in BSD systems work very well.
The nvidia model of E6400 isn't recommended for other
reasons, namely: poor thermal cooling (thermal pad on
the GPU) and that Nvidia GPU doesn't get very good
performance on any libre drivers anyway. The Intel GPU
variant is better, in terms of power efficiency and
software support; the intel variant also works with
native graphics initialisation in coreboot.
This board port already only enables SeaBIOS, which will
simply execute the VGA ROM. Blobutil already supports
reading the config, detecting that a VGA ROM is needed,
because that part of the WIP E6400 branch was already
merged in lbmk master.

* grub.cfg in memdisk instead
* grub.cfg in memdisk defers to cbfs/grub.cfg if added
(not added by default, anymore)
* does not defer to grubtest.cfg even if available
* only shows link to grubtest.cfg if available,
as a menuentry item
keymaps:
if /keymap.gkb exists in cbfs, it uses that by default,
but by default this isn't added. instead, it looks for
a file named keymap.cfg and sources that, which then
sets the keymap to one that is located under memdisk.
this file is inserted for each rom, per layout.
if keymap.gkb and keymap.cfg both absent, grub.cfg in
memdisk shall defer to usqwerty as the default keymap
grub_scan_disk: grub.cfg looks for cbfs file "scan.cfg"
and sources that if found, which will be inserted with
the string: set grub_scandisk=setting_goes_here (based
on target.cfg, generated by build/boot/roms automatically).
If no scan.cfg is found, it defaults to "both"
The "background.png" file remains unchanged, and present in
CBFS, used by grub.cfg if present (and it is, by default)
This change actually *saves* space in CBFS, due to compression,
and means that the grub.cfg is now compressed heavily. This
is also safer, because now the user overrides grub.cfg by
adding it, and they can still add grubtest.cfg for testing
first. If they accidentally delete both configs from cbfs,
Libreboot will fall back to the one in memdisk which would
presumably not be deleted.
This also means that lbmk can now more easily be used by
other build systems, that just want the GRUB part to re-use
in their own project. For example, people who want to build
custom coreboot images without using Libreboot's build system.
This change also *speeds* up the build process considerably,
on the parts where ROM images are copied. It's less than half
a second now, whereas previously it took about 30-45 seconds
for ROM images to copy, because of grub.elf being re-added in
each ROM via cbfstool, where compression is used; I believe
the compression part is what caused slowness.
Much, much faster, more versatile builds.
