Make TPM dependency optional and controlled by flag CONFIG_TPM
if "CONFIG_TPM=y" is not present in the config file, functionalities
needing TPM could be disabled, while leaving other functionalities intact.

This will make Heads a more general-usage bootloader payload atop coreboot.

Replace remaining text-only options in main workflow w/ gui menus
In particular I added a GUI menu to instruct the user if there is no
TOTP code registered (as is the case upon first flash) and also added
better handling of the case the user selects 'default boot' when there
is no default boot set yet. Apart from that where there were text-only
menus left in gui-init I've replaced them with GUI menus.

Add gui option to kexec-select-boot, use in gui-init menu option
When selecting the boot menu option (m) in the gui-init you call out to
kexec-select-boot. To better maintain the graphical menu experience,
I've added a -g option to kexec-select-boot that, when set, will use a
graphical whiptail menu for the most common menu selection modes.

Add graphical init menu that uses whiptail
This is a modified version of the generic-init script that uses whiptail
to generate a graphical menu. I changed two of the options so that the
user can refresh the menu to get an updated TOTP code if needed.

baa30a2026 Add OHCI and UHCI drivers to initrd.
USB smart card readers are most full speed devices, and there is no
"rate-matching hubs" beneath the root hub on older (e.g. GM45) plat-
forms, which has companion OHCI or UHCI controllers and needs cor-
responding drivers to communicate with card readers directly plugged
into the motherboard, otherwise a discrete USB hub should be inserted
between the motherboard and the reader.

This time I make inserting linux modules for OHCI and UHCI controllable
with option CONFIG_LINUX_USB_COMPANION_CONTROLLER.

A linux config for x200 is added as an example.

Tested on my x200s and elitebook revolve 810g1.

Added the ability to persist a default boot option
Similar to qubes-update, it will save then verify the hashes of
the kexec files. Once TOTP is verified, a normal boot will verify
that the file hashes and all the kexec params match and if
successful, boot directly to OS.

Also added a config option to require hash verification for
non-recovery boots, failing to recovery not met.

Added a generic boot config and persistent params
Refactored boot parsing code and applied that in local-init to
scan /boot for grub options and allow the user to unsafely boot
anything.  This goes a long way to addressing #196.

Optionally the user can customize those boot parameters or enforce
arbitrary hashes on the boot device by creating and signing config
files in /boot/ or /media/ or /media/kexec_iso/ISO_FILENAME/.

adds a USB boot option with basic parsing to kexec
Supports booting from USB media using either the root device or
a signed ISO as the boot device.  Boot options are parsed with
quick/dirty shell scripts to infer kexec params.

Rework /init and qubes setup scripts (issue #27, #155, #32, #29, #110)
This adds support for seamless booting of Qubes with a TPM disk key,
as well as signing of qubes files in /boot with a Yubikey.

The signed hashes also includes a TPM counter, which is incremented
when new hashes are signed.  This prevents rollback attacks against
the /boot filesystem.

The TPMTOTP value is presented to the user at the time of entering
the disk encryption keys.  Hitting enter will generate a new code.

The LUKS headers are included in the TPM sealing of the disk
encryption keys.

TPM disk encryption keys for Qubes.
Issue #123: This streamline Qubes startup experience by
making it possible to have a single-password decryption.

Issue #29: The disk keys in `/secret.key` are passed to the systemd
in initramfs through `/etc/crypttab`, which is generated on each boot.
This is slow; need to look at alternate ways.

Issue #110: By using LVM instead of partitions it is now
possible to find the root filesystem in a consistent way.

Issue #80: LVM is now included in the ROM.

Move Qubes startup script to /boot/boot.sh
This also adds a set of files in the qubes/ directory that
are meant to be copied to the /boot partition.

Issue #154: for ease of upgrading Qubes, the script should
live on /boot instead of in the ROM.  This requires a GPG
signature on the startup script to avoid attacks by modifying
the boot script.

Issue #123: this streamlines the boot process for Qubes, although
the disk password is still not passed in correctly to the initrd
(issue #29).

This does not address issues #110 of how to find the root device.
The best approach is probably disk labels, which will require
special installation instructions.
