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.
x86 qemu is on todo for libreboot, on all x86 boards,
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)

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
Signed-off-by: Leah Rowe <leah@libreboot.org>
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.
the ESP is always mounted as its own partition,
FAT32, and EFI/ is always at the root of it
Signed-off-by: Leah Rowe <leah@libreboot.org>
the esp is always a fat32 partition so this makes no sensgrub.cfg: don't scan EFI on btrfs subvols

the reason for it is because sometimes the coreboot build
system auto-downloads submodules which we don't want.
however, we now pass UPDATED_SUBMODULES=1 in make, which
disables this behaviour in coreboot's build system.
therefore, remove this unnecessary logic.

i'm merging it into lbmk after this commit. in lbmk, it
will be used for deleting certain files such as u-boot's
strlcat.c. it will not be used in libreboot for deblobbing;
that's what canoeboot is for (deblobbed coreboot distro).

this effectively lets you change the boot order. example:
./build roms -s "nvme ata" t1650_12mb
the above example would set:
grub_scan_disk="nvme ata"
another example:
./build roms -s nvme t1650_12mb
this would set:
grub_scan_disk="nvme"
this overrides what's set in target.cfg for the given
target. useful for quick reconfiguration if building
from source

there's a copying file anyway. put spdx in the config
Signed-off-by: Leah Rowe <leah@libreboot.org>
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.

Well, fix is the wrong word. We want xHCI ideally.
Mate is working on it as I write this. I've also:
* Disabled CONFIG_FINALIZE_USB_ROUTE_XHCI on Haswell
boards (coreboot)
* Disabled the GRUB payload on HP 820 G2 for now
We will need to re-add the xHCI patches once fixed.
If Mate/we can't fix it, I'll contact Patrick
Rudolph who originally wrote the xHCI patches.

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.

as stated in the previous commit, i'm adding this function
to lbmk because there are files i want to systematically
delete in libreboot releases, not just canoeboot releases,
but libreboot releases delete things such as unlicensed
readme files, or poorly licensed other files.
i initially moved the nuke function to its own file so as
to reduce the number of merge conflicts when merging
changes to git.sh between cbmk and lbmk, but if they're
going to both contain this file, then it makes sense
to have this in git.sh once again.

blobs.list is now nuke.list
this is because i'm going to import this functionality
into lbmk (libreboot build system).
libreboot will not do full deblobbing like canoeboot does,
but there are still certain files that i like to delete
in releases, such as u-boot's strlcat.c file under tests
calling it "nukeblobs" in libreboot makes no sense, but
i like to avoid merge conflicts when cherry-picking
patches between cbmk and lbmk, so i like to make sure
that functions and variables common to both are named
the name.
simply calling it "nuke" or calling the files "nuke.list"
is probably inoffensive while conveying the same meaning.

put in place in case someone downloaded a tarball from codeberg

it wasn't being reset before. when coreboot is being
built, i add to makeargs every time. if multiple targets
are being built, the make command would end up looking
something like:
make -C src/coreboot/default UPDATED_SUBMODULES=1 \
UPDATED_SUBMODULES=1
(the parameter would be printed twice)
of course, this doesn't check whether that parameter is
added already in target.cfg for a given target, but that's
ok because i won't add that one in target.cfg
i baked it into the code, only when handling coreboot,
because that was easier than either putting it in makeargs
for every coreboot target.cfg, or again modifying the code to
handle that; the current solution is the cleanest.
