This patchset adds appropriate bindings for parsing various bcm963xx NOR flash layouts found in the wild. The image header is quite limited, and only has fixed fields for the offsets and sizes of the kernel and rootfs partitions. If any additional partitions exist, they need to be described externally, e.g. through fixed partition layouts. The first two patches add the bindings for the full flash parser for the "common" case: first erase block bootloader, last erase block nvram, reminder available for firmware. The third patch splits out the image header parsing into its own parser. Then patches four and five add bindings for the split out parser, to support non-trivial cases with additional partitions, or a non-standard offset of the firmware partition. These patches have been in used since a while in OpenWrt.
