Leah Rowe 37817e6bcb GRUB: insert only 1 keymap per board, in cbfs
There is no need to add multiple keymap files, because
GRUB can load keymaps from CBFS. The current build logic
is designed to avoid building multiple GRUB binaries,
which are expensive computationally because each one
would then have to be compressed for each board.

This patch provides the best of both worlds: less space
used in flash like in the old lbmk design (1 keymap per
board), but retaining the current build speeds and therefore
not re-introducing the slowness of lbmk's previous GRUB
build logic.

The grub.cfg file has been modified, accordingly. It now
only loads a keymap.gkb file from CBFS, by default. It does
this, only if that file exists; if not, GRUB already defaults
to US Qwerty layout anyway.

ALSO: compress all keymap gkb files with xz -6

GRUB automatically decompresses files when accessed.
This results in about 2KB of flash space saved in CBFS.

Here is real-world data, showing the increased flash space:

< fallback/payload               0x3eb80    simple elf     548821 none
< keymap.cfg                     0xc4bc0    raw                16 none
< (empty)                        0xc4c00    null         11633316 none
---
> fallback/payload               0x3eb80    simple elf     546787 none
> keymap.gkb                     0xc43c0    raw               344 none
> (empty)                        0xc4540    null         11635044 none

This was taken by diffing the cbfstool "print" output,
both before and after. The *after* result is with this change.
11633316. In this example, 1728 bytes have been saved. Therefore,
with compression taken into account, this patch saves about 1.7KB
of space in CBFS.

This change means that lbmk can now scale to support hundreds
of keymaps, without increasing the amount of flash space used,
in each given image. Since the keymap files are compressed in
lbmk.git, in advance, we spend no additional time on compression
at build time. The resulting change in build speed in negligible.

Adding your own keymap.gkb file was already possible, for changing
the keymap in libreboot images, if you didn't want to change the
memdisk (and thus re-compile grub.elf). Now, this is the default
behaviour, and the only way to do it. It's much more efficient.

The original keymap files can be restored, by running unxz.

Leah Rowe 4c9ee172be update/trees: support custom make/autogen argument
this is now used in grub, for the FS_PAYLOAD_MODULES
option in the make command

lbmk should generalise as much logic as possible. in
some parts of it, logic is hurrently hardcoded, specific
to a given project that lbmk uses, but lbmk is essentially
a source-based package manager, like what you might find
on a small linux distro, so we need to try to
be as generic as possible.

lbmk is the "build system of build systems", so it has to
work generically with as many of them as possible

Leah Rowe b061558104 update/trees: dont hardcode autoconf/bootstrap arg
at present, the bootstrap and configure script is only
directly executed for grub, because grub is the only
project that uses them in lbmk

however, when i start adding linuxboot support, i will
have to start building a lot of projects, some of which
make use autoconf and bootstrap scripts

e.g.

./bootstrap --foo
./configure --bar

the "bootstrap" script is often used on GNU programs,
because they like to over-engineer absolutely everything

This reverts commit 20389655e4.

If the user actually has encryption, but has /boot unencrypted,
this will considerably slow down the boot, so the patch has
been reverted.

The patch was originally meant to favour encrypted /boot
setups, but the old behaviour also still works there.

Leah Rowe 026d57fff4 GRUB: don't spew "Unknown key 0xff" in error
Faulty keyboards make GRUB unusable. Normally it happens
when a user plugs in a faulty USB keyboard, but if it's
the laptop keyboard, then GRUB becomes unusable and the
user cannot boot anything.

So, your laptop keyboard is a ticking timebomb if you use
GRUB; with this patch, that's no longer the case.

Leah Rowe 9606c68c5b fix grub keyboard init on dell e6400 and e6430
also, enable seabios_withgrub on e6400, but not grubfirst;
right now, we also support dgpu which would brick on
grubfirst. on my tested nvidia model, loading grub from
seabios worked, so i'm going to re-add seabios_grubfirst
functionality like in older libreboot revisions, enabled
selectively on a given target.

e6430 currently only has igpu support anyway, but i've done
the same thing there, in anticipation of future dgpu support.

e6400 and e6430 ec report scancode set 2 with translation
by default, but only actually output scancode set 1

grub is trying to use scancode set 2 without scancode
translation, so the key inputs get messed up

fix it by forcing scancode set 2 with translation, but
only on coreboot; other build targets on GRUB will
retain the same behaviour as before

courtesy goes to Nicholas Chin who inspired me, and
helped me to fix this. tested on Nicholas's E6400
and E6430, and my E6400; Riku also tested it on
non-Dell, as did I (some thinkpads), and all seems OK.

The new behaviour in coreboot GRUB is essentially no
different to that of SeaBIOS, which does the same.
