   9 We allowed using bcm47xxpart on BCM5301X arch with commit:
  10 9e3afa5f5c7 ("mtd: bcm47xxpart: allow enabling on ARCH_BCM_5301X")
  11
  12 BCM5301X devices may contain some partitions in higher memory, e.g.
  13 Netgear R8000 has board_data at 0x2600000. To detect them we should
  14 use size limit on MIPS only.
