%description
First stage bootloader fimware upgrade package for Raspberry Pi 4

How this is meant to work:

The update mechanism writes recovery.bin and the EEPROM update image(s)
(pieeprom.upd and vl805.bin) to the EFI partition. The SHA256 hash of the
corresponding images are written to pieeprom.sig and/or vl805.sig. This guards
against file system corruption which could cause the EEPROM to be flashed with
an invalid image. This is not a security check.

At the next reboot the ROM runs recovery.bin which updates EEPROM(s).  If the
update was successful recovery.bin renames itself to RECOVERY.000 to prevent it
from running a second time then resets the system.  The system should then boot
normally.

Upon upgrading rasperrypi-firmware-eeprom we make sure that the RECOVERY.000 is
deleted, so as not to bloat the EFI partition.
