When testing a possible boot device, detect its partition type and
skip grub, LUKS, and LVM partitions. These aren't mountable as /boot,
this silences spurious exFAT errors.
In detect_boot_device, skip testing CONFIG_BOOT_DEV a second time if it
is found as a block device. This avoids doubling any errors shown from
checking this device, no sense trying it twice.
Refactor some logic to avoid duplication - extract
device_has_partitions and use it in detect_boot_device, extract
mount_possible_boot_device and use it instead of duplicating the logic.
Move find_lvm_vg_name() to /etc/functions.
Avoid mixing up similarly-named devices like 'nvme0n1'/'nvme0n10' or
'sda'/'sdaa' - it's probably unlikely that many devices will appear,
but looking for partitions in '/sys/class/block/<device>/' instead of
'/dev/' would avoid any collisions.

Since exFAT support was enabled, mounting an iso9660 filesystem prints
spurious exFAT errors to the console. That is because busybox mount
tries all filesystems in the order listed, and exfat precedes iso9660
(those are the last two in our config). Most filesystems are silent
when used on the wrong type of filesystem, but exFAT logs errors, which
appear on the console.
Move exFAT after iso9660, so iso9660 filesystems won't show these
errors. The errors will still appear if the filesystem is actually
exFAT but cannot be mounted.
There's no significant risk of misdetecting a remnant iso9660
superblock here either. Although an iso9660 superblock could fall in
the unused space between the exFAT boot region and the FAT itself,
mkfs.exfat does zero this space so it is unlikely such a remnant
superblock would exist.

Next steps on this is introspection and PCRs reconstruction helpers, which will output in DEBUG and be usable from recovery shell.
We have to keep in mind that providing those tools is useful in DEBUG mode and for users having access to Recovery Shell.
But currently, having access to cbmem -L output and final PCRs content is making it too easy for Evil Maid to know what needs to be hardcoded to pass measured boot.

When playing with long fbwhiptail/whiptail messages, this commit played around the long string using fold.
'''
echo -e "This will replace the encrypted container content and its LUKS Disk Recovery Key.\n\nThe passphrase associated with this key will be asked from the user under the following conditions:\n 1-Every boot if no Disk Unlock Key was added to the TPM\n 2-If the TPM fails (hardware failure)\n 3-If the firmware has been tampered with/modified by the user\n\nThis process requires you to type the current LUKS Disk Recovery Key passphrase and will delete the LUKS TPM Disk Unlock Key slot, if set up, by setting a default boot LUKS key slot (1) if present.\n\nAt the next prompt, you may be asked to select which file corresponds to the LUKS device container.\n\nHit Enter to continue." | fold -w 70 -s
'''
Which gave the exact output of what will be inside of the fbwhiptail prompt, fixed to 70 chars width:
'''
This will replace the encrypted container content and its LUKS Disk
Recovery Key.
The passphrase associated with this key will be asked from the user
under the following conditions:
1-Every boot if no Disk Unlock Key was added to the TPM
2-If the TPM fails (hardware failure)
3-If the firmware has been tampered with/modified by the user
This process requires you to type the current LUKS Disk Recovery Key
passphrase and will delete the LUKS TPM Disk Unlock Key slot, if set
up, by setting a default boot LUKS key slot (1) if present.
At the next prompt, you may be asked to select which file corresponds
to the LUKS device container.
Hit Enter to continue.
'''
Therefore, for long prompts in the future, one can just deal with "\n 1-" alignments to be respected in prompts and have fold deal with cutting the length of strings properly.

Don't spew the root hashes to the console when creating the hash file.
This speeds up hash creation significantly. A basic Qubes install on a
cheap (slow) SATA SSD reduced from about 1.5 minutes to just under 1
minute, and a PureOS install on a fast NVMe disk reduced from 2.5
minutes to 1 minute.
Support opening LVM volume groups to find the root disk. If an LVM PV
is found, its group is opened and the 'root' volume is used. There is
no way to set the volume name in this iteration; this is the default
name used by Qubes and probably common to many LVM OS installations.
LUKS and LVM can be mixed. Tested LUKS (PureOS) and LUKS+LVM (Qubes).
Always cd to "$ROOT_MOUNT" in a subshell, improves robustness of
scripts (previously some functions only worked if they were called
after another function had cd'd to "$ROOT_MOUNT").

Add TRACE_FUNC to trace the file, line, and name of the calling
function. File and function names don't have to be duplicated in a
TRACE statement with this (they tend to become inaccurate as functions
are renamed and the TRACE statement is forgotten).
Add DEBUG_STACK to dump the bash stack to debug output.
Configure bash with --enable-debugger. Bash doesn't actually include
the entire debugger, this is just some supporting variables for it.
Evidently, BASH_SOURCE[n] is only set within a function if this is
enabled. I couldn't find this indicated in any documentation, but it
happened in practice.
Compressed initrd size only increased by 2560 bytes for librem_mini_v2,
I think that is fine. This also gives us BASH_ARGC/BASH_ARGV which
might be useful for diagnostics.

Rebuild the kernel 6.1.8 config for Librem devices starting from the
current 5.10 config as a base. The current 5.10 config had cleaned up
some unneeded options, but that hadn't been carried over to the 6.1.8
config.

Laptops can include optional USB keyboard support (default off unless
the board also sets the default to 'y'). The setting is in the
configuration GUI.
CONFIG_USER_USB_KEYBOARD is now the user-controlled setting on those
boards. 'CONFIG_USB_KEYBOARD' is no longer used to avoid any conflict
with prior releases that expect this to be a compile-time setting only
(conflicts risk total lock out requiring hardware flash, so some
caution is justified IMO).
Boards previously exporting CONFIG_USB_KEYBOARD now export
CONFIG_USB_KEYBOARD_REQUIRED. Those boards don't have built-in
keyboards, USB keyboard is always enabled. (librem_mini,
librem_mini_v2, librem_11, librem_l1um, librem_l1um_v2, talos-2,
kgpe-d16_workstation-usb_keyboard, x230-hotp-maximized_usb-kb).
Librem laptops now export CONFIG_SUPPORT_USB_KEYBOARD to enable
optional support. The default is still 'off'.

If we can't mount /boot, show a meaningful error rather than dropping
to a recovery shell.
Dropping to a recovery shell should be a last resort. Users that know
how to use the recovery shell know how to get there. Users that don't
know how to use it can be completely stuck and may not know how to get
back to the menu or even how to turn off the device.

The Ada compiler is only used for libgfxinit - Intel native graphics

Download coreboot toolchain archives into packages/<arch> before
coreboot tries to download them. This allows us to use mirrors to get
the archives. We could also update the primary source this way if it
goes down instead of patching coreboot itself (has happened for IASL).
The archive versions and digests are retrieved from the coreboot
module, so there isn't another copy of that info to maintain. That is
done in bin/fetch_coreboot_crossgcc_archive.sh, which uses the
existing fetch script to do the actual download, leveraging mirrors.
bin/fetch_source_archive.sh supports using a SHA-1 digest instead of
SHA-256, since coreboot has SHA-1 digests. It also checks if the file
already exists (deleting the coreboot directory will cause it to be
re-run, but the packages are already there and can be used from cache).
The coreboot-4.11 IASL patch is updated to delete the outdated acpica
archive digest (it already added the new one, but the old one was still
there). bin/fetch_coreboot_crossgcc_archive.sh finds the archive
version and digest from the digest files, so only one acpica file must
be present.

Use the Heads name for a package when it differs from the primary
source. E.g. musl-cross-make's archive is just <hash>.tar.gz, which
makes little sense out of context. musl-cross-<hash>.tar.gz makes
more sense for a mirror.

Try to download dependency source packages from mirrors if the primary
source fails or the archive has changed.
Move the download and verify logic to bin/fetch_source_archive.sh. The
mirror list is here, currently only
https://storage.puri.sm/heads-packages/, but others can be added. The
mirror list is randomized to load each mirror equally.
The verify logic is moved to this script too so it can fail over to a
mirror (or another mirror) if a mismatched archive is served, not just
for a failure. Makefile no longer needs to verify separately and there
are no separate .*-_verify files any more, the archive is only moved to
its final place once verified.
Add `packages` target to just fetch all needed packages for a board,
facilitates seeding a mirror.
