Or rather try a > more recent version of U-Boot ;) one 832x or 836x (keymile tuda/tuxa I believe) board implemented bootcounting, and it used QE MURAM for that storage space. The 8313 doesn't have a QE though. So unless someone finds such storage space on the non-QE 83xx SoCs, it's not elegant, but it should be ok for 83xx bootcount to depend on CONFIG_QE. Note that because MURAM is also now used to store the bootcount, its size is decreased in fdt_fixup_muram() before booting the OS.
