3 Subject: [PATCH] mtd: bcm47xxpart: limit scanned flash area on BCM47XX (MIPS)
6 Content-Type: text/plain; charset=UTF-8
7 Content-Transfer-Encoding: 8bit
9 We allowed using bcm47xxpart on BCM5301X arch with commit:
10 9e3afa5f5c7 ("mtd: bcm47xxpart: allow enabling on ARCH_BCM_5301X")
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.
