1Broadcom BCM963XX CFE Loader NOR Flash Partitions
2=================================================
3
4Most Broadcom BCM63XX SoC based devices follow the Broadcom reference layout for
5NOR. The first erase block used for the CFE bootloader, the last for an
6NVRAM partition, and the remainder in-between for one to two firmware partitions
7at fixed offsets. A valid firmware partition is identified by the ImageTag
8header found at beginning of the second erase block, containing the rootfs and
9kernel offsets and sizes within the firmware partition.
