on 3050micro, we disable seabios as a primary payload,
making grub a pribary payload instead.
the way it worked, the roms were still named seagrub
and the seabios rom would be compiled, but with the wrong
path, so seabios wouldn't be executed; seabios would hang
anyway, on this board.
instead, engineer it in such a way as to disable seabios_
images on this board. also, rename seagrub_ to grub_.
i normally only permit seagrub, and not grub, but i make an
exception for 3050micro because we know grub works, but seabios
currently hangs on this board (which means no bsd).

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.

musl libc is very conservative in what it implements,
preferring a very "pure" libc implementation. this means
that it lacks many of the niceties found in others like
the GNU C Library; the latter implements many BSD libc
extensions, for example.
ACCESSPERMS is a #define in BSD libc that does:
S_IRWXU | S_IRWXG | S_IRWXO
Essentially, it provides a bitwise OR providing chmod 0777,
which can be used as shorthand in calls to functions such
as mkdir() available in all libc implementations.
In the case of uefitool, this define is indeed used on mkdir.
Conditionally re-define ACCESSPERMS, if undefined, so that musl
libc can be used when building uefitool.

this time, only handle multiple keymaps on seagrub

not immediately load grub, whether grub is still
available in flash, just do one image (US Qwerty)

Commit 46e01c0e1d ("u-boot: Avoid building U-Boot-only binman images")
added a patch that prevents an error while building U-Boot, due to some
U-Boot images needing a copy of BL31 that we are not passing in.
Removing build instructions for these images isn't really necessary,
when we can instead tell the build tool that it shouldn't exit with an
error. It checks a BINMAN_ALLOW_MISSING environment variable for this,
but just unconditionally replace the check with the argument.

no longer neccessary as the issue is fixed, and my QEMU patches were
merged upstream, so drop these patches. One patch we have to disable
binman images can be replaced by a simpler alternative so drop it too.
Upstream kconfig status is still unstable, so updating configs with
`make oldconfig` would miss important upstream changes, since they rely
on carrying defaults via upstream defconfigs. Update the configs as
such, like before:
- Turn old configs into defconfigs (./update trees -s u-boot)
- Save the diff from old upstream defconfig (diffconfig $theirs $ours)
- Update U-Boot revision, rebase patches, and clean old trees
- Prepare new U-Boot tree (./update trees -f u-boot)
- Review the diffconfigs to see if any options were renamed upstream
- Copy over the new upstream defconfigs and apply earlier diff
- Turn new defconfigs into configs (./update trees -l u-boot)

move the coreboot-specific includes into mkhelper.cfg
for that project.
on some projects, we need variables from mkhelper.cfg
to be global, so I was including serprog and coreboot
mkhelper.cfg files in this script.
instead, set a new variable "mkhelpercfg" pointing to
the config file. if it doesn't exist, create and then
point to a temporary (empty) mkhelper.cfg file.
the rom.sh include has been moved to coreboot mkhelper.cfg
The only remaining project-specific logic, in this trees
script, is now the coreboot crossgcc handling, but this
needs to be there as it's also used to build U-Boot.
The way this now works, certain includes are done twice.
For example, include/rom.sh will be included once globally,
outside of main(), and then again in configure_project().
This means that certain functions will be defined twice.
I'm uncertain if shell has anything equivalent to an ifdef
guard as in C, but we actually want this here anyway, and
it shouldn't cause any problems. It's a bit of a hack, but
otherwise results in much cleaner code.

-d does the same as -b, except for actually building
anything! in effect, it does the same as -f (fetch)
except that the resulting variable assignments will
not be recursive (as with -f).
if -d is passed, configuration is still loaded, defconfig
files are still cycled through, and more importantly:
helper functions are still processed.
the grub, serprog and coreboot helper functions have
been modified to return early (zero status) if -d is
passed.
this behaviour will be used to integrate vendor.sh
logic in with the trees script, for cases where the
user wants to only handle vendor files. e.g.:
./update trees -b coreboot x230_12mb
this would download the files as usual, build coreboot,
with those files, and then build the payloads. but:
./update trees -d coreboot x230_12mb
this would download the files, NOT build coreboot, and
NOT build the payloads.
this change increases the sloccount a bit, but i'm relying
on the fact that the vendor.sh script already re-implements
config handling wastefully; the plan is to only use trees.
for now, simply stub the same ./vendor download command.
there is one additional benefit to doing it this way:
this method is *per-kconfig* rather than per-target.
this way, one kconfig might specify a given vendor file
that is not specified in the other. although the stub
still simply handles this per target, it's done in premake,
which means that the given .config file has been copied.
this means that when i properly re-integrate the logic
into script/trees, i'll be able to go for it per-kconfig.
the utils command has been removed, e.g.
./update trees -b coreboot utils default
the equivalent is now:
./update trees -d coreboot default
this would technically download vendor files, but here
we are specifying a target for which no kconfigs exist;
a check is also in place, to avoid running the vendor file
download logic if tree==target
the overall effect of this change is that the trees script
no longer contains any project-specific logic, except for
the crossgcc build logic.
it does include some config/data mkhelper files at the top,
for serprog and coreboot, so that those variables defined in
those files can be global, but another solution to mitigate
that will also be implemented in a future commit.
the purpose of this and other revisions (in the final push
to complete lbmk audit 6 / cbmk audit 2) is to generalise as
much logic as possible, removing various ugly hacks.

stub it from the trees script. the way it works now,
there is less code in the build system.
./build roms
this is no longer a thing
./build roms serprog
this is also no longer a thing. instead, do:
./update trees -b coreboot targetnamehere
./update trees -b pico-serprog
./update trees -b stm32-vserprog
the old commands still works, which causes the new
commands to run
coreboot roms now appear in elf/, not bin/, as before,
but those images now contain payloads.
NOTE: to contradict the above: ./build roms is no
longer a thing, in that it's now deprecated, but
backward compatibility is present for now. it will
be removed in a future release.
./build roms list also still works! it will do:
./update trees -b coreboot list
also:
./update trees -b grub list
this is now possible too
if a target "list" is provided, for multi-tree sources,
the targets are shown.
there is another difference: seagrub roms are now seagrub_,
instead of seabios_withgrub.
seabios-only roms are no longer provided, where grub is also
enabled; only seagrub is used. the user can easily remove
the bootorder file, if they want seabios to not try grub first.

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.

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.

the background is only a few kb. the whole rationale
before was to limit the space used in memdisk, but this
decision was made when the background was much bigger;
it has since been optimised greatly, and the grub modules
were heavily reduce, so it should be safe.
grub's memdisk breaks when you add too much data to it.
as part of simplifying the rest of lbmk, this change removes
some more bloat from the rest of lbmk. handling this in the

support redundant downloads, and enable inclusion of these
tarballs inside release archives, for offline builds.
Signed-off-by: Leah Rowe <leah@libreboot.org>
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.

Re-add xHCI only on haswell and broadwell machines, where
they are needed. Otherwise, keep the same GRUB code.
The xHCI patches were removed because they caused issues
on Sandybridge-based Dell Latitude laptops. See:
https://codeberg.org/libreboot/lbmk/issues/216
The issue was not reported elsewhere, including on the
Haswell/Broadwell hardware where they are needed, but the
build system could only build one version of GRUB.
The older machines do not need xHCI patches, because they
either do not have xHCI patches, or work (in GRUB) because
they're in EHCI mode when running the payload.
So, the problem is that we need the xHCI patches for GRUB
on Haswell/Broadwell hardware, but the patches break
Sandybridge hardware, and we only had the one build of GRUB.
To mitigate this problem, the build system now supports
building multiple revisions of GRUB, with different patches,
and each given coreboot target can say which GRUB tree to use
by setting this in target.cfg:
grubtree="xhci"
In the above example, the "xhci" tree would be used. Some
generic GRUB config has been moved to config/data/grub/
and config/grub/ now looks like config/coreboot/ - also,
the grub.cfg file (named "payload" in each tree) is copied
to the GRUB source tree as ".config", then added to GRUB's
memdisk in the same way, as grub.cfg.
Several other design changes had to be made because of this:
* grub.cfg in memdisk no longer automatically jumps to one
in CBFS, but now shows a menuentry for it if available
* Certain commands in script/trees are disabled for GRUB,
such as *config make commands.
* gnulib is now defined in config/submodule/grub/, instead
of config/git/grub - and this mitigates an existing bug
where downloading gnulib first would make grub no longer
possible to download in lbmk.
The coreboot option CONFIG_FINALIZE_USB_ROUTE_XHCI has been
re-enabled on: Dell OptiPlex 9020 MT, Dell OptiPlex 9020 SFF,
Lenovo ThinkPad T440p and Lenovo ThinkPad W541 - now USB should
work again in GRUB.
The GRUB payload has been re-enabled on HP EliteBook 820 G2.
This change will enable per-board GRUB optimisation in the
future. For example, we hardcode what partitions and LVMs
GRUB scans because * is slow on ICH7-based machines, due
to GRUB's design. On other machines, * is reasonably fast,
for automatically enumerating the list of devices for boot.
Use of * (and other wildcards) could enable our GRUB payload
to automatically boot more distros, with minimal fuss. This
can be done at a later date, in subsequent revisions.

in practise, the machines we support don't have

this hardcoding is done to avoid using *, which is
slow in grub on some machines (the grub kernel always
re-enumerates the devices during every operation,
without caching any of it)
yet, the hardcoding is also slow; balance it a bit
better by searching fewer permutations, but not so few
that it would likely break a lot of setups

Previously, grub_scan_disk could set ata, ahci or "both",
which would make both be tried (ahci first). This worked
when we only dealt with ata and ahci devices, but now we
support nvme devices so the logic is inherently flawed.
Instead, use grub_scan_disk to store the boot order, e.g.:
grub_scan_disk="ahci nvme ata"
grub_scan_disk="nvme ata"
In the first example, it would make GRUB scan ahci first,
then nvme and then ata.
In the secontd example, it would make GRUB scan nvme first,
and then ata.
If "both" is set, or anything other than ahci/ata/nvme,
grub_scan_disk is now changed to "nvme ahci ata".
Actual grub_scan_disk entries in target.cfg files will now
be modified, to match each machine.

Almost all users will be OK running GRUB, but a
minority of users have experienced a fatal error
pertaining to grub_free() or grub_realloc() (as
my investigation of GRUB sources reveal when grepping
the error reported in the link above).
We don't yet know what the bug is, only that the
error occurs, leading to an effective brick if the
user has GRUB as their primary payload.
So far, it has only been reported on some Intel
SandyBridge-based Dell Latitudes in Libreboot, but
we can't be too sure.
The user reported that memtest86+ passes just fine,
and SeaBIOS works; BIOS GRUB also works, which means
that the bug is likely only in an area of GRUB that
runs specifically on the coreboot payload, so it's
probably a driver in GRUB when running on the metal
rather than BIOS/UEFI.
The build system supports a configuration whereby
SeaBIOS is the primary payload, but GRUB is available
in the SeaBIOS boot select menu, and an additional
configuration is available where GRUB is what SeaBIOS
executes first (while still providing boot select);
both of these are now the *only* configurations
available, on all x86 targets except QEMU.
The QEMU target is fine because if the bug occurs there,
you can just close QEMU and try a different image.
Even after this bug is later identified and fixed,
the GRUB source code is vastly over-engineered and there
are likely many more such bugs. SeaBIOS is a reliable
payload; the code is small and robust. Remember always:
Code
equals
bugs
Therefore, this configuration change is likely going
to be permanent. This will apply in the next release.
