The MTDPARTS currently lists just u-boot.ais as 512k in size. This works when loading the ais file via serial port, but if one wanted to update just the u-boot portion, it's not really possible. This patch splits the MTDPARTS into a 32k SPL partiion and a 480k u-boot partition which allows u-boot.img to be burned to the u-boot partition. The remaining partitions are left with the same sizes and offsets to not break backwards compatibility.
