The patches were generated from the RPi repo with the following command: git format-patch v6.6.34..rpi-6.1.y Some patches needed rebasing and, as usual, the applied and reverted, wireless drivers, Github workflows, READMEs and defconfigs patches were removed.

Subject: [PATCH 0132/1085] firmware: raspberrypi: Report the fw variant during
 | 
						|
 probe
 | 
						|
 | 
						|
The driver already reported the firmware build date during probe.
 | 
						|
The mailbox calls have been extended to also report the variant
 | 
						|
 1 = standard start.elf
 | 
						|
 2 = start_x.elf (includes camera stack)
 | 
						|
 3 = start_db.elf (includes assert logging)
 | 
						|
 4 = start_cd.elf (cutdown version for smallest memory footprint).
 | 
						|
Log the variant during probe.

firmware: raspberrypi: Report the fw git hash during probe
 | 
						|
 | 
						|
The firmware can now report the git hash from which it was built
 | 
						|
via the mailbox, so report it during probe.
