+mtd: bcm47xxpart: detect block aligned Squashfs partition
+
+Most of the bcm47xx devices use TRX format for storing kernel and some
+partition like Squashfs or JFFS2. This is pretty flexible solution, CFE
+(the bootloader) just writes (and later boots) TRX at some hardcoded
+place and paritions can vary in the size.
+
+However some devices don't use TRX format. Very recently we have
+discovered ZTE H218N that has kernel and rootfs partitions at some
+"random" places.
+
+This patch allows Linux find a rootfs partition after installing custom
+image with a CFE bootloader.
