only use config/submodules/ which the build system then
uses to run git clones manually, replicating the submodules
feature. we must never use a project's own gitmodules feature,
because we can't easily control it. better to let it break first,
and then figure out what modules to add manually, so that we
have only what we need for each project.
it's done this way, because git's own submodules feature
doesn't have very good error checking in general, nor
does it have good redundancy.
with the current design, we can declare backup repositories
for each submodule.
we replicate it precisely. for example:
3rdparty/vboot
this is a coreboot submodule, and we handle that in the
coreboot trees.
however, our current design also allows you to do this even
if the upstream repository does not contain a .gitmodules file

again: the "depend" variable must never be used for subprojects
that point to a subdirectory of the main project, because there's
no clean way of handling this in case of error conditions.
make it a submodule under config/submodules/. this is for the
documentation, including static site generator documentation,
and image files (photos).
as of this revision, there are now only those "depend" projects
defined in config/git/, where the destination directory of the
subject is not a subdirectory of the main project, so:
in a subsequest revision, i will mitigate an existing bug whereby
failure of the dependency project leaves the main one still
intact, breaking builds; this revision enables that to be done.
from now on, subproject-to-subdirectory-of-main-project will
be avoided in config/git/; config/submodules/ will be used.

same as the previous patch, we must no longer use "define"
variables in config/git/ when the path is a subdirectory of
a given project, because it means that the download can only
happen after the main one, and currently if that fails, the
download of the main repo would remain intact, breaking future
builds in ways that we can't control - to be clear, it could
be controlled, but with added code complexity in the build
system, so:
put it in config/submodules/
Signed-off-by: Leah Rowe <leah@libreboot.org>
don't define it as a "depend" variable in config/git/,
because it means putting the files in a subdirectory of
an existing project was was already then downloaded, and
that means it can't be downloaded first; if the download
of it fails, the old download is left intact.
this bug isn't currently fixed in the build system, at all,
so this and other patches are being made to mitigate it.

now it no longer hardcodes a check for whether the

instead, check for the presence of target.cfg files
not in config/project/ but config/project/tree/
the way this check is done, it merely returns 1 if
config/project/*/target.cfg is detected, and returns
0 in all other cases, even if config/project/target.cfg
exists
that way, if the maintainer accidentally adds a
target.cfg in the main directory, the given multi-tree
project will not break

this avoids writing the version/versiondate files as root.
this complements the previous fix, that avoided writing those
same files when running the dependencies command.
initial setup of the build system requires root, to run the
dependencies script, but otherwise the build system prevents
running as root for everything else, so we must avoid writing
the version/versiondate files as root.
that same avoidance is necessary when checking whether running
other commands as root; ironically, this check then prevented
running the build system at all!
the bug should be fully fixed now. i found this quite by accident
the other day, when testing something else.
good thing this got fixed because the release!

do it strategically, in just the right place so that the
version and versiondate files aren't written.
otherwise, version/versiondate are written as root and
the build system becomes unusable after that, unless you
reset the file ownerships from root. hardly user-friendly.

already of saying "found", say "already exists"
this means the output of these commands more user
friendly and intuitive:
./update trees -b grub default
./update trees -b coreboot i945
this is just an example. when an ELF file already
exists, the build is skipped even if src isn't downloaded.
this design is intentional, because it means that you can
use previous builds if you want to save time on another.

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, but we still don't
need xHCI support in Canoeboot's GRUB because none of the
available coreboot targets have xHCI support. However, we
may want it in the future and it helps to keep Canoeboot
in sync with Libreboot (this patch is adapted from lbmk).
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.
There is another reason for merging this design change from
lbmk, and that reasoning also applies to lbmk. Specifically:
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.

it doesn't build, at present, but isn't used by any
coreboot targets, so the build issue does not come up
during release builds, but i did find it laying around
during my audits.

but the current config is broken, so: remove it.

in practise, the machines we support don't have
the option of including so many disks; 8 seems like
the most reasonable default. additionally, it's
unreasonable to expect *20 partitions*
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
Signed-off-by: Leah Rowe <leah@libreboot.org>
we already supported syslinux but not grub
support grub by scanning for the most common paths,
based on the most popular distros
we don't hardcode this with * because it slows down
the boot, and in practise many distros still use the
same grub.cfg location as in BIOS systems (the EFI
one is often just a link to the BIOS one)
Signed-off-by: Leah Rowe <leah@libreboot.org>
this is a relic from the old days when we didn't
automated the grub.cfg logic as much. these days,
the grub.cfg logic is able to boot almost all distros
without any manual intervention or override.
removing these entries will speed up the boot in general

the path "/boot/EFI" is unnecessary because the ESP
is always a FAT32 partition, so we don't need to
scan it as a subdirectory within a subdirectory.

FAT32, and EFI/ is always at the root of it
