This also increases the (necessarily) hardcoded initrd end by 16MiB in
the DTS, which is necessary to make the phone boot with the new
initramfs (and in general any initramfs which exceeds 2624KiB).
This wasn't actually getting run on boot because After=graphical.target
created an ordering issue and systemd was disabling it.
I saw this ordering issue in the journal after finding that pbsplash was
still running in the background after the UI loaded, and confirmed it by
running systemd-analyze.
The referenced commit had surfaced a bug with the unlocking code, which
would attempt to change the output of find_root_partition while the
cached PMOS_ROOT is stale and active. Clear this variable to force
find_root_partition to find the new rootfs value.

This seems to be some Samsung's proprietary verified boot solution.
After a recent update, this started bootlooping my phone.
I have no idea why it only fired now, but pmOS does not use this
feature anyway, so it won't hurt to disable it.

Drop the console-shell hook in favour of stuffing buffyboard into the
initramfs. This makes it possible to get a debug shell directly on the
device without needing to use a computer.

Rework the messages and avoid re-spawning the splash on every check.
Additionally, add a call to check_keys, this lets users drop to a debug
shell or export logs to triage this failure (particularly useful for
hard-to-reproduce issues).
Finally, add a (liberal) 30 second timeout and dump logs at the end. If
we're just waiting for a device to show up and it doesn't after 30
seconds then it's probably never going to...

In mount_subpartition we currently try to look for the boot partition,
to see if we're done (either we aren't using subpartitions or we found
the right one). However it is possible that a device might have
originally used the subpartition scheme, but was later converted to have
a real boot partition (for EFI for example).
In this scenario, the boot partition would be found immediately, but the
root subpartition would not be.
Address this by making mount_subpartition check for success by calling
find_root_partition instead of find_boot_partition. For most
installations this has no impact.

Which can have significant performance impact on affected devices,
such as the Librem5 or the PinePhone.
The patch already landed upstream, however a new release is likely
several weeks or months away, making a backport worthwhile.

Install a kill-pbsplash systemd service which is configured to be
started as part of the graphical-session user target. Additionally
install an override so that if the display-manager service (aliases to
gdm, sddm, etc) fails to start it will still kill pbsplash.

Currently, dtbtool-sprd has an argument -p which accepts the path to the
dtc binary. When it's not provided, it should use the dtc binary installed
in the system as a fallback. However, that's not the case. The following
error is reported:
Found file: test.dtb ... skip, failed to scan for 'sprd,sc-id = <' tag
...even though test.dtb has the `sprd,sc-id` property.
In order to mitigate such issues, install dtc as a dependency of the
package.
Without it some devices will fail to mount the boot partition:
FAT-fs (mmcblk1p1): IO charset ascii not found
Also disable CONFIG_RT_GROUP_SCHED.

This cmdline argument is now a no-op. Drop it everywhere and add a new
CI check to enforce this.
Adjust the deprecated "minimal" initramfs variant to use
pmos.debug-shell to enable logging instead. It doesn't /support/
dropping to a shell, so the variable takes on a different meaning. But
that's ok since it's at least more consistent.
