956 the end of the partition table is marked with a zero byte.
957
958 The firmware image must contain at least the partition-table and support-list partitions
959 to be accepted. There aren't any alignment constraints for the image partitions.
960
961 The partition-table partition contains the actual flash layout; partitions
962 from the image partition table are mapped to the corresponding flash partitions during
963 the firmware upgrade. The support-list partition contains a list of devices supported by
964 the firmware image.
965
966 The base offsets in the firmware partition table are relative to the end
967 of the vendor information block, so the partition-table partition will
968 actually start at offset 0x1814 of the image.
