These changes primarily improve server boards using BMC video. The
correct DRI card is selected even if it isn't the first one, and
performance is greatly improved on non-UMA cards.

This is particularly beneficial for servers with Aspeed BMC video,
because it introduces framebuffer console acceleration. The
framebuffer console is much more responsive.
Patches were ported from 5.10.5:
0001-fake-acpi.patch: This may not be needed any more, but it applies
cleanly and I don't think it would harm anything.
0002-nmi-squelch.patch: The comment mentions qemu but I see this
message on physical machines occasionally, so I think this is needed.
0003-fake-trampoline.patch: This patch does not apply cleanly. It
could be ported, but I don't think it's needed, I dropped it. Dates
back to a very old commit where Linux was being embedded into a vendor
UEFI firmware: a4d7654b1e.
0010-winterfell-ahci.patch: Minor change of %x to %lx in context.

PureBoot doesn't have any other three-valued settings and this doesn't
present very well in the config UI.
Instead make this a two-valued setting; drop the mode that forces the
EC setting to "stay off" at every boot because this is the default.
When disabling automatic power-on, disable the EC BRAM setting too.

Stop manually loading config values, just update config in environment.
Never test values against "n", since many default to empty. Always
test ="y" or !="y", any other value is off.
Add set_user_config() function to set a value in config.user,
combine configs, and update config in environment. Use it in setting
implementations.
Remove toggle_config, it wasn't very useful because the settings still
test y/n in order to show specific confirmation and success messages.

Blob jail provides device firmware blobs to the OS, so the OS does not
have to ship them. The firmware is passed through the initrd to
/run/firmware, so it works with both installed and live OSes, and there
are no race conditions between firmware load and firmware availability.
The injection method in the initrd is specific to the style of init
script used by PureOS, since it must add a copy command to copy the
firmware from the initrd to /run. If the init script is not of this
type, boot proceeds without device firmware.
This feature can be enabled or disabled from the config GUI.
Blob jail is enabled automatically if the Intel AX200 Wi-Fi module is
installed and the feature hasn't been explicitly configured.

USB autoboot automatically boots to a USB flash drive if one is present
during boot. This is intended for headless deployments as a method to
recover the installed operating system from USB without needing to
attach a display and keyboard.
USB autoboot can be controlled in config.user and the config GUI.

Restricted Boot mode only allows booting from signed files, whether that
is signed kernels in /boot or signed ISOs on mounted USB disks. This
disables booting from abitrary USB disks as well as the forced "unsafe"
boot mode. This also disables the recovery console so you can't bypass
this mode simply by running kexec manually.

PureBoot Basic mode provides the full Linux userspace in firmware from
Heads without requiring verified boot or a Librem Key. Basic and
verified boot can be switched freely without changing firmware, such as
if a Librem Key is lost.
PureBoot Basic can apply firmware updates from a USB flash drive, and
having a complete Linux userspace enables more sophisticated recovery
options.
Basic mode boots to the first boot option by default, setting a default
is not required. This can be configured in the config GUI.

Add these two functions for use in config-gui.sh for future toggles.
load_config_value() obtains the value of a config setting, defaulting
to 'n'. get_config_display_action() displays 'Enable' or 'Disable'
depending on the current value.

Currently Heads will check files in /boot for tampering before booting
into a system. It would be nice if you could use the trusted environment
within Heads and extend this to check files in / itself. This new script
adds that functionality, however due to the length of time it takes to
perform these kinds of checks, it doesn't run automatically (yet).
This feature can be configured from the config GUI - the root device/
directories to check can be set, and it can be configured to run during
boot.
To make this a bit easier to use, I added a feature to detect whether
the hash file exists and if not, to display a more limited menu to the
user guiding them to create the initial hash file. Otherwise it will
display the date the file was last modified, which can be useful to
determine how stale it is.
Reduce friction when generating a new TOTP/HOTP secret by eliminating
an unnecessary 'press enter to continue' prompt following QR code
generation, and by attempting to use the default admin PIN set by
the OEM factory reset function. Fall back to prompting the user
if the default PIN fails.
Also, ensure error messages are visible to users before being returned
back to the GUI menu from which they came by wrapping existing calls to die()

On machines without a TPM, we'd still like some way for the BIOS to
attest that it has not been modified. With a Librem Key, we can have the
BIOS use its own ROM measurement converted to a SHA256sum and truncated
so it fits within an HOTP secret. Like with a TPM, a malicious BIOS with
access to the correct measurements can send pre-known good measurements
to the Librem Key.
This approach provides one big drawback in that we have to truncate the
SHA256sum to 20 characters so that it fits within the limitations of
HOTP secrets. This means the possibility of collisions is much higher
but again, an attacker could also capture and spoof an existing ROM's
measurements if they have prior access to it, either with this approach
or with a TPM.
