Just some minor clean ups like fixing whitespace and sorting things. I
added (bash)/removed (libusb) white space in order to look like the
other modules.
I sorted the --enable/--disable/--with blocks so that common stuff
looked similar which should aid in comparing modules. I also removed a
couple of duplicate config options (--disable-fallback-curses &

When playing with long fbwhiptail/whiptail messages, this commit played around the long string using fold.
'''

'''
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.

Add TRACE_FUNC to trace the file, line, and name of the calling

Add DEBUG_STACK to dump the bash stack to debug output.
Configure bash with --enable-debugger. Bash doesn't actually include

Evidently, BASH_SOURCE[n] is only set within a function if this is

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'.

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.

Rationale:
cpio -t alone cannot extract initrd past early cpio (microcode) in most packed initrd.
unpack_initramfs.sh already under master comes to the rescue, but its usage up to today was limited to pass firmware blobs to final OS under boards/librem_mini_v2
Debian OSes (and probably others) need to have cryptroot/crypttab overriden directly, otherwise generic generation of crypttab is not enough.
Extracting crypttab and overriding directly what is desired by final OS and exposed into /boot/initrd is the way to go otherwise hacking on top of hacks.
This brings default packed modules under Heads to 5 modules, which needs to be deactivate in board configs if undesired:
user@heads-tests-deb12:~/heads$ grep -Rn "?= y" modules/ | grep -v MUSL
modules/zlib:1:CONFIG_ZLIB ?= y
modules/zstd:3:CONFIG_ZSTD ?= y
modules/exfatprogs:2:CONFIG_EXFATPROGS ?= y
modules/busybox:2:CONFIG_BUSYBOX ?= y
modules/e2fsprogs:2:CONFIG_E2FSPROGS ?= y
prepare_thumb_drive: default to creating 10% LUKS container on usb drive, prompts for passphrase is not provided and scan drives if no --device specified
NOTE: qemu usb_thumb drive of 128 mb are not big enough so that 10% of it (12mb) can be used to create thumb drive.
Adds:
- e2fsprogs to support ext4 filesystem creation through mke2fs
- add /etc/mke2fs.conf so that mke2fs knows how to handle ext2/ext3/ext4
- removes mke2fs support from busybox
- bump busybox to latest version which adds cpu accelerated hash functions (not needed per se here)
- Adds exfatprogs to have mkfs.exfat and fsck.exfat
- Adds prepare_thumb_drive /etc/luks-functions to be able to prepare a thumb drive with percentage of drive assigned to LUKS, rest to exfat
- Modify most board configs to test space requirements failing
- Talos2 linux config: add staging Exfat support
- Make e2fsprogs and exfatprogs included by default unless explicitely deactivate in board configs
- Change cryptsetup calls : luksOpen to open and luksClose to close to addresss review
- etc/luks_functions: cleanup
GOAL here is to have secure thumb drive creation which Heads will be able to use to backup/restore/use generated GPG key material in the future (next PR)

At one time coreboot was built using Heads' musl toolchain, but this
was later reverted. coreboot builds with its own toolchain again.
CROSS= has no effect on coreboot proper (only exception is PPC64
skiboot payload). It was added to coreboot by a patch that was deleted
in 8e44853. COREBOOT_IASL was set to the default, that was only needed
when the toolchain was being overridden to override iasl back to the
coreboot one.
ppc64 still specifies CROSS= since skiboot is unable to find coreboot's
toolchain from XGCCPATH but checks CROSS. This builds skiboot with the
Heads toolchain as before.

On some newer platforms of intel (confirmed on nehalem, sandy/ivy
bridge), coreboot after commit [2ac149d294af795710eb4bb20f093e9920604abd](https://review.coreboot.org/cgit/coreboot.git/commit/?id=2ac149d294af795710eb4bb20f093e9920604abd)
registers an SMI to lockdown some registers on the chipset, as well
as access to the SPI flash, optionally. The SMI will always be triggered
by coreboot during S3 resume, but can be triggered by either coreboot
or the payload during normal boot path.
Enabling lockdown access to SPI flash will effectly write-protect it,
but there is no runtime option for coreboot to control it, so letting
coreboot to trigger such SMI will leave the owner of the machine lost
any possibility to program the SPI flash with its own OS, and becomes
a nightmare if the machine is uneasy to disassemble, so a scheme could
be implement, in which the SMI to lockdown chipset and SPI flash is left
for a payload to trigger, and temporarily disabling such triggering in
order to program the SPI flash needs authentication.
I have implemented a passcode-protected runtime-disableable lockdown
with grub, described [here](https://github.com/hardenedlinux/Debian-GNU-Linux-Profiles/blob/master/docs/hardened_boot/grub-for-coreboot.md#update-for-coreboot-after-commit-2ac149d294af795710eb4bb20f093e9920604abd). In order to implement a similar scheme for
Heads, I wrote [io386](https://github.com/hardenedlinux/io386).
With this commit, io386 will be called before entering boot routine
to trigger the SMI to finalize the chipset and write protect the SPI
flash at the same time. Entering recovery shell will leave the flash
writable.
(The authentication routine implemented in previous revisions has been
split as an independent commit.)
