1356 The firmware image must contain at least the partition-table and support-list partitions
1357 to be accepted. There aren't any alignment constraints for the image partitions.
1358
1359 The partition-table partition contains the actual flash layout; partitions
1360 from the image partition table are mapped to the corresponding flash partitions during
1361 the firmware upgrade. The support-list partition contains a list of devices supported by
1362 the firmware image.
1363
1364 The base offsets in the firmware partition table are relative to the end
1365 of the vendor information block, so the partition-table partition will
1366 actually start at offset 0x1814 of the image.
