BCM2711 and BCM2712 require different EEPROM firmware and
consequently the binaries have been moved to chip specific
firmware directories.
firmware-2711 / firmware-2712
Update the test/install script to remove previous firmware files.
This fixes a problem where the install script failed because
beta is now a symlink and not a directory.
Move to to the old directory now that it's no longer referenced by rpi-eeprom-update.
Add a dependency check for 'lspci' which is normally provided by
pciutils or busybox and remove the failover to the vl805 helper.
Tweak the failure messages for missing dependencies to be slightly less
OS specific.
* New beta recovery.bin which can update the VLI EEPROM before
start.elf is loaded. This is the recommended and default method
because no USB devices will be in use at this stage.
* Extend the USE_FLASHROM configuration to use the vl805 tool
to program the VL805 directly.
* Generate SHA256 checksums in .sig files for the bootloader and
and VL805 images. This is required by the new recovery.bin to
guard against corrupted files being flashed to the EEPROM(s).
* Various variable renames to distinguish between the bootloader
and the VL805 images.
