+Subject: [PATCH] mtd: bcm47xxpart: limit scanned flash area on BCM47XX (MIPS)
+ only
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+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.
