+Subject: [PATCH] mtd: handle partitioning on devices with 0 erasesize
+
+erasesize is meaningful for flash devices but for SRAM there is no
+concept of an erase block so erasesize is set to 0. When partitioning
+these devices instead of ensuring partitions fall on erasesize
+boundaries we ensure they fall on writesize boundaries.
