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