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.

single-tree projects cannot be handled in bulk, e.g.
./mk -f project1 project2 project3
that is still the case, from the shell, but internally
it is now possible:
mk -f project1 project2 project3
mk() is a function that simply handles the given flag,
and all projects specified.
it does not handle cases without argument, for example
you cannot do:
mk -f
arguments must be provided. it can be used internally,
to simplify cases where multiple single-tree projects
must be handled, but *also* allows multi-tree projects
to be specified, without being able to actually handle
trees within that multi-tree project; so for example,
you can only specify coreboot, and then it would run
on every coreboot tree.

this is another alternative to the previous fix. this one
is therefore now a pre-emptive fix, in case other code is
written in the future that makes use of badhash.
the badhash variable in a y/n variable, so initialise to n.
Signed-off-by: Leah Rowe <leah@libreboot.org>

when badhash=y, the utils should be deleted, but
the check is deleting if badhash isn't n. if the
hash check isn't being performed, then this will
always be the case and the utils are always deleted.
make it positively delete the file only if badhash=y,
not when it isn't n. while this may not sound very
different, it will prevent the utils being deleted and
re-build endlessly in other cases, like when building
release archives and running the inject --nuke mode
on every image that gets built.

we want multiple seagrub images made, with different
keymaps, but we only want one non-seagrub image.
however, we also want grub in the non-seagrub image.
it just means that seabios is primarily what the user
wants, and they might occasionally use grub, whereas
the seagrub images are for people who primarily want
grub but may occasionally access the seabios menu.
right now, the seabios images really only contain seabios,
but there's no harm in adding grub to them.

don't rely on build/coreboot.rom staying in place,
because sometimes it can get purged under certain

this time, only handle multiple keymaps on seagrub
images. for images where seabios is first but does
not immediately load grub, whether grub is still
available in flash, just do one image (US Qwerty)
this still results in fewer images per target than
Libreboot 20240612, but should prevent most users
from being annoyed. i got a few people asking
repeatedly, and i hadn't documented yet how to add
keymap.gkb or how to remove bootorder, to get a
different keymap or disable seagrub respectively.
i anticipate that i'll get such questions a lot, even
if i do document it, so i'm reversing that decision.
it doesn't result in much extra code. the new design
in lbmk makes this sort of thing much simpler.

i actually only made this change so that the revision changes,
so that the release directory changes when doing:

the me_extract function prefixes it with PWD in
some cases, but we can't predict where appdir

XBMK_CACHE is now used, instead of hardcoding cache/
this is exported initialised to cache/, if unset.
this means you can set your own directory, and it means
./update release will use the same directory.

if coreboot itself is being handled, crossgcc has the
correct makeargs, setting the number of build threads.
however, other projects can specify "xtree" pointing to
a given coreboot tree, and build crossgcc for it.
one workaround may be to use trees -d coreboot TREE,
but then extra code would have to be written to make
it avoid other things like building cbfstool, which is
not required for just building crossgcc.
the cleanest way to do it is to simply hardcode it. the
value is set exactly the same as regular coreboot makeargs.
this fixes a bug, where some builds of crossgcc are made
on a single thread, rather than using XBMK_THREADS. this
patch forces it to always use CPUS=$XBMK_THREADS

lbmk must still define payloads, but specific configs
may use coreboot's build system instead.
you might use this to add your own config with, say,
tianocore payload, using coreboot.git to build it,
rather than using lbmk's choice of payloads.

lib.sh download() is used by subfile handling in git.sh,
e.g. crossgcc tarballs, and also the vendor scripts.
vendor files are cached, but not subfiles for repos.

to the checksum, so: cache/file/CHECKSUM

if doing a retry, the directory may still exist, which
would make git clone yield an error response; the existing
directory will have been the one that failed to reset, so
let's delete it.
the one deleted is not the cache (repo/PROJECT/), thus
otherwise maintaining current behaviour.

normally, a project is cached at repo/PROJECT/, and
cloned from there to the final destination.
errors lead to a calling of $err, but this will result
in a return if done from inside a subshell, of non-zero
value, so use this to re-try with a 6th argument when
calling tmpclone().
in most cases, this fallback will never kick in, but
it will kick in resetting or patching the cached clone
fails; specifically, we are interested in the reset part.
a given project name may change repositories in lbmk at
a given time. if this happens, and the old one is cached,
the overall result of this patch is that lbmk will fall
back to the old behaviour, where git urls are tried
directly, without caching.

actual source code is not scanned, but config directories are
scanned. simply get the checksum of each file under config/
pertaining to a given project/tree, and also for the given
target. coreboot utilities are also handled.
if it changes, in any way, delete and re-build automatically.
such deletions should probably still be done manually, as part
of understanding the build system, but this change should make
the build system much easier to use during development.

do it based on the URL, e.g. https://review.coreboot.org/coreboot
becomes repo/coreboot
the downside is if you have two projects with repo urls specifying
the same string at the end, but this isn't the case at the moment
and likely won't be the case, but it's a theoretical issue.
this saves on bandwidth when downloading identical submodule repos
between multiple trees within the same multi-tree project
for example, coreboot 3rdparty/vboot is no longer downloaded more
than once, instead cloned locally on subsequent downloads.
if repo/DIR exists, git-pull is attempted, but errors do not result
in a non-zero exit, by design.

configure_project is a bit big. move the dependencies
build logic to a new function.
it may be desirable in future to make the way that
function works the way all build commands are done.
for example:
./update trees -b coreboot x230_12mb
would become:
./update trees -b coreboot/x230_12mb
this would enable to mix and match multi/single tree
projects. for now, leave things as they are.

U-Boot has migrated to using upstream device-tree files for gru boards,
but the clock driver doesn't yet support setting rates for a certain
clock that upstream uses for the eDP display. It happens to work without
it, so for now remove the clock setting until the driver is fixed.

Commit 46e01c0e1dad ("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.

Set default U-Boot revision to v2024.07 and rebase patches on top of
that. One patch that fixes drawing box characters (UTF-8 to CP437) had
an alternative merged, another hack we have to fix regulator issues is
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)

main() used to be the only function executed from
outside of main(), in this script, but now we source
a config file and then run the build afterward.
when a flag is provided without OPTARG, this means
that we are continuing such action erroneously. to
mitigate this, return 1 in that instance, and handle
it in the line that calls main(), making it exit with
zero status (success).

instead of using lots of if/else conditions, do that once
and set a variable, dry, to :
if not doing a dry run, the variable is empty. prefix this
variable in places where you don't want a certain action to
be performed, on dry runs.
more specifically, : does *nothing* and always returns with
zero status (success).
this results in cleaner code, and a small sloccount reduction.

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.
