BCM2711 and BCM2712 require different EEPROM firmware and
consequently the binaries have been moved to chip specific
firmware directories.
firmware-2711 / firmware-2712
Previously, the .sig would have an update timestamp of zero. Switching
to rpi-eeprom-digest is preferable because the update timestamp will
be much closer to when the image was installed.
N.B. Update-timestamp is used to track configuration changes and is
independent of the build-timestamps which are the version of the
bootloader executable.
Create an EEPROM update zip files for use with the Raspberry Pi Imager.
The Raspberry Pi Imager JSON will soon be updated to support the 3
different boot priority choices offered by raspi-config.
