If you don't have such registers, a bit of reserved SDRAM might be a solution. That already implemented for some boards. See bootcount_store() and bootcount_load() in: board/keymile/km_arm/km_arm.c This "RAM bootcount driver" will be moved to a common location by the bootcount consolidation patches that are pending.
