994 The firmware image must contain at least the partition-table and support-list partitions

996
997 The partition-table partition contains the actual flash layout; partitions
998 from the image partition table are mapped to the corresponding flash partitions during
999 the firmware upgrade. The support-list partition contains a list of devices supported by
1000 the firmware image.
1001
1002 The base offsets in the firmware partition table are relative to the end
1003 of the vendor information block, so the partition-table partition will
1004 actually start at offset 0x1814 of the image.
