From: Rafał Miłecki Date: Sat, 5 Dec 2015 01:09:43 +0000 (+0100) Subject: mtd: bcm47xxpart: limit scanned flash area on BCM47XX (MIPS) only X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=2a36a5c30eab9cd1c9d2d08bd27cd763325d70c5;p=linux-beck.git mtd: bcm47xxpart: limit scanned flash area on BCM47XX (MIPS) only 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.
