916 fwup-ptn os-image base 0x01000 size 0x113b45

918 fwup-ptn support-list base 0x2e4b49 size 0x000d1
919
920 Each line of the partition table is terminated with the bytes 09 0d 0a ("\t\r\n"),
921 the end of the partition table is marked with a zero byte.
922
923 The firmware image must contain at least the partition-table and support-list partitions
924 to be accepted. There aren't any alignment constraints for the image partitions.
925
926 The partition-table partition contains the actual flash layout; partitions
927 from the image partition table are mapped to the corresponding flash partitions during
928 the firmware upgrade. The support-list partition contains a list of devices supported by
929 the firmware image.
930
931 The base offsets in the firmware partition table are relative to the end
932 of the vendor information block, so the partition-table partition will
933 actually start at offset 0x1814 of the image.
934
935 I think partition-table must be the first partition in the firmware image.
