at present, lbmk can remove microcode updates on images for
a given target, if the target specifies
microcode_required="n" in target.cfg
lbmk then provides images with microcode, and images without,
in a given release. although the user can also remove them
manually, this just makes it a bit more convenient, for those
users who do wish to run without the updates. this functionality
is provided only on those platforms where no-microcode is tested.
well, this behaviour implements a compromise on libreboot policy,
which is to always include microcode updates by default. see:
Binary Blob Reduction Policy
the *canoeboot* project now exists, developed in parallel with
libreboot, and it ships without microcode updates, on the same
targets where lbmk also handled this.
running without microcode updates is foolish, and should not
be encouraged. clean up lbmk by not providing this kludge.
the libreboot documentation will be updated, telling such users
to try canoeboot instead, or to remove the update from a given
libreboot rom - this is still possible, and mitigations such as
PECI disablement on GM45 are still in place (and will be kept),
so that this continues to work well.

don't handle "romtype" at all, in board target.cfg files
add /dev/null as pike2008 rom on amd boards. this serves
the same purpose, adding them as empty vga roms, to add
an empty rom in cbfs. pike2008 cards cause seabios to hang,
when their oproms are executed, so we insert a fake rom
on i945 thinkpads, use the coreboot config option:
CONFIG_INTEL_ADD_TOP_SWAP_BOOTBLOCK
when set, this enables the same bootblock copy, for use
with bucts. these two cases, namely pike2008 roms and
i945 bootblock copies, no longer need to be handled in code

only call crossgcc for coreboot and u-boot, but use
hostcc for everything else. simplify the checking of
which architecture to compile for. "arch" in target.cfg
files has been modified, to allow further simplification.
without this patch, the logic currently only *barely* avoids
using crossgcc on things like utils, and only works in practise
because, in practise, lbmk only works on x86_64 anyway.
the new logic, as per this patch, is simpler and more robust.

the ddr2 fix broke *ddr3* on gm45 thinkpads in
testing, depending on memory modules. this was
established by removing patches, re-doing
configs etc, on a user's X200 (testing gentoo
and freebsd). the X200 kept randomly rebooting
or having random glitches.
the configs themselves (gm45 thinkpads) will
also be re-done, because i found minor issues
unrelated, but this patch moves dell e6400 to
its own tree. the ddr2 fix is no longer present
in coreboot/default, only coreboot/dell.
i noticed minor differences in gm45 thinkpad
configs, when re-doing the configs, versus
what are currently in lbmk master; for instance,
vbt was not enabled anymore, on thinkpad x200.
modifications to these will be done separately.

it didn't work in the past, but it does work nowadays;
specifically, it only worked with libgfxinit in the past,
but not on VGA ROMs.
now it does work on VGA ROMs, tested on e6400 and t1650 so
it was enabled there.
in this setup, a special image is provided where SeaBIOS is
the main payload, but it only loads GRUB; nothing else, every.
this is called SeaGRUB. this setup is useful in cases where
the user only has a GPU that lacks libgfxinit support.

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.
