+Subject: [PATCH] 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.
+
