nowadays, we don't insert GRUB keymaps automatically, for
sake of efficiency; without one, the default is US QWERTY.
a user will only want one keymap in particular, so this
is more efficient. in practise, they're either building
from source anyway, or using the inject scripts which
compile cbfstool anyway, so the user will already have
cbfstool.
also output this message from the inject script.

there are two for loops that use x as a variable anme,
and an idiosyncrasy of certain sh implementations is
that these become global;
the result in this case was that when you finish building
every target in "./build roms", it would print "libgfxinit"
repeatedly, comma separated, instead of a comma-separated
list of the targets that were built.
work around it by renaming the variable in one of the loops.

cbcfg is already a global variable, so there's no reason
to set it again at the start of this function.
remove the check for whether the given coreboot config
exists, to the calling function instead of build_roms().

we don't need to call mktemp everytime.
just use a staticly named file in tmpdir
and keep overwriting it.
these files are only small, and they get deleted
when the build system exits later on.

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
memdisk is much simpler than handling it with cbfstool.

if not inserted, the default keymap is usqwerty.
don't waste ssd write cycles copying so many images,
or cpu time compressing so many. the user can simply
add a keymap.gkb file to cbfs and it will work fine.
this will be documented in the next release.

the current validation check is extremely over-engineered,
because the user override is no longer available and we're
always very careful in how we modify target.cfg per board.
remove the redundant code. trust that target.cfg is correct.

p = payload
s = grub_scan_disk
d = displaymode
setting the payload is no longer safe, due to issue 216
and similar issues that might pop up in the future; it's
best left only to target.cfg, per board, so that we know
what config is safe/tested. don't let the user override it.
scandisk isn't safe to override because the given machine
may not have the type of device that the user specifies
displaymode is actually ok to set, because it simply whitelists
what configs pre-existing to actually use, but it's bloat
basically, the rule is this:
don't make it easy for the user to brick their hardware.
make it harder instead.
a user wily enough to go modifying their payload will probably
have read docs/maintain/ anyway and knows how to edit target.cfg
if they want another board configuration.

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.

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

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.
