the shellball (for extracting the coreboot rom, to get
at mrc.bin) contains lines that are not posix-friendly.
specifically, the "local" command is used, and this is
not defined for posix sh.
the shellball is essentially just a bunch of shell
functions that compress/decompress the zip file,
containing the firmware update. you can modify the
files and re-run the shellball to recompress, though
lbmk just uses the decompress function.
as pointed out by Nicholas Chin, it is possible to just
run "unzip" directly on the update, to get at bios.bin.
we don't really need all the extra checks performed by
the shellball, so let's just bypass it altogether.

the x220 edp patch invalidated lots of configs, so
i did: ./update trees -u coreboot
this is the resulting patch
Signed-off-by: Leah Rowe <leah@libreboot.org>
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 component 1 and 2 densities were still set to 8 MiB and 4 MiB
respectively, which is incorrect for 16 MiB only configurations.
Change the component 1 density to 16 MiB so that the address space
gets properly mapped to SPI 1. In addition, change the number of
components field (byte 0x15) to 0x00 to indicate 1 flash chip.

Inside the BIOS update, there's 68SCE and 68SCF variants.
Based on Qubes HCL and browsing linux-hardware.org, these are
Probook 6360b and Elitebook 8460p respectively.
I checked the KBC1126 EC Firmwares within the update file, both
use the exact same firmware images. Following-up will be a very
similar but untested port for 6360b.

remove unnecessary "continue" command. it's written
at the end of a for loop, where it'll continue anyway
Signed-off-by: Leah Rowe <leah@libreboot.org>
this part of the code *must* return. the for loop
afterwards must not be permitted to execute.
it's unlikely that this would ever occur, unless
perhaps the user is using a very buggy sh.

there are special menuentries just for loading
configs, without handling luks, lvm and whatnot.
it's intended for users of cd/dvd drives. well,
now we support both extlinux and grub, with this patch.

isolinux/syslinux/extlinux config files should all work,
using the syslinux parser function in grub
the current behaviour is to only search for grub.cfg,
so extlinux users can't use the default libreboot setup.
with this change, their systems should hopefully work.

the so-called EFI System Partition (ESP) is used
on many UEFI-based setups. some users may be
migrating to libreboot, so let's support it.
on BIOS setups, it would be e.g.
/boot/syslinux/syslinux.conf
on UEFI setups, it would be e.g.
/boot/EFI/syslinux/syslinux.conf
additionally, support scanning for extlinux.conf

lvm/* is slow to resolve in grub, on some machines,
because grub enumeration is very slow in general.
however, many people will install distros with any
number of lvm configurations, so we should try to
support them.

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.
when the user sets up an encrypted machine, grub.cfg
defaults to non-encrypted setups if found, first
this patch reverses the order, deferring to
non-encrypted installations only when encrypted ones
are unavailable

These systems have a report that the unlock utility does not work.
Until there are multiple reports of failed unlocks and a technical
determination of why it doesn't work, they will not be listed as
explicitly unsupported.
As this utility requires access to /dev/mem, the default protections of
Linux and OpenBSD must be relaxed to allow this. Make a note of this in
the instructions.
The old Open Security Training site had a course called Advanced x86:
BIOS and SMM Internals, which had a set of slides outlining the method
to supress SMIs by changing the GBL_SMI_EN bit. Add a reference to it as
this is where I originally learned of this method.
all it did was set -v in the shell, which doesn't yield
very useful results. this is a relic of very old design
in the libreboot build system, that is no longer needed.

lbmk didn't quote certain arguments in commands, or
used ! -z instead of -n, things like that. simple fixes.

most of these are probably redundant, and will never
be called, but lbmk needs to be as safe as possible
under fault conditions. fail early, fail hard.

update/trees wasn't correctly returning non-zero status,
even though it was printing an error message, when git-am
failed. this is due to the way subshells work, and it was
overlooked in previous auditing.
additionally: don't directly copy trees to the destination,
instead patch/reset first, then copy only under normal
condition, just as with single-tree projects.
when running build/roms, the script would continue after
a bad git-am, without exit. this patch fixes it in the
most paranoid way possible. i'm now fairly confident that
lbmk will fail gracefully and efficiently, under error
conditions. this should prevent bad image builds.
