1328 The firmware image must contain at least the partition-table and support-list partitions

1330
1331 The partition-table partition contains the actual flash layout; partitions
1332 from the image partition table are mapped to the corresponding flash partitions during
1333 the firmware upgrade. The support-list partition contains a list of devices supported by
1334 the firmware image.
1335
1336 The base offsets in the firmware partition table are relative to the end
1337 of the vendor information block, so the partition-table partition will
1338 actually start at offset 0x1814 of the image.
