+Subject: [PATCH] mtd: bcm63xxpart: handle Broadcom partition order
+
+The original Broadcom partition order has the root fs in front of the
+kernel, which resulted in miscalculated partition sizes.
+Detect when such an image is on the flash and also reorder the partitions
+accordingly.

+Subject: [PATCH 22/79] MTD: bcm63xxpart: make fixed part length calculation
+ more generic
+
+The CFE does not use 4K sectors even if the flash supports it, so
+for the fixed partitions like CFE itself or NVRAM the erase block
+size is always 64k or bigger.
