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.

install libfreetype-dev, instead of libfreetype6-dev
this still works in debian stable (currently 12.2) but
fixes debian sid, as of 15 November 2023. my test machine
with debian sid could not install libfreetype6-dev, but
could install libfreetype-dev

apparently some people use fat file systems for /boot
on linux systems
this is apparently a thing
it's ridiculous, but also a thing
a user reported they could not boot their t400 because
of those, because they have such a distro installed
on their machine
apparently it was a gentoo user
i don't really care. re-add 1980s dos file system support.

in cases where lbmk must always return from a function,
there are some cases where it relies on non-zero exit
status, which in practise is always the case, but may
change in the future if the relevant part is modified
e.g. do_something && return 0
the proper form is:
do_something
return 0
also do this for unconditional exits

don't run it directly at the bottom of err.sh,
because otherwise the version and versiondate
files will be generated when running "./build
dependencies distroname" which would then create
these files, but as root because the user runs
that specific command as root.
the rest of lbmk, for any other command, prevents
use of the root account, so running check_project
during "./build dependencies distroname" will cause
the build system to fail (because as non-root user,
the user will run lbmk and it will try to update
those files, and fail because it can't, due to lack
of permissions)
this patch fixes the issue, by only generating those
files if the user is *not* root

Fix a few issues with the E6430 configs to make it consistent with
configs for other boards and function as intended.
- Add VBT to CBFS: Although the VBT was enabled at the board level
Kconfig in a previous commit (CONFIG_INTEL_GMA_HAVE_VBT), the config
to actually add the VBT to CBFS was still unset.
- Enable the static option table: The old config would always use the
fallback values hard coded in the coreboot tree, rather than the
settings in the cmos.default file
- Enable DRAM clear on boot: This was not set previously, even though
most other boards set this for security.
