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.
