my-mkimage previously did not include the fs_mark of deadc0de because upon formatting of jffs2 partition, U-Boot's CRC validation would not allow the image to boot. This new MTD map will shrink the kernel+rootfs+fs_mark image and recalculate the CRC, so that only the kernel is part of the image validation. This also improves boot time, since less is copied from FLASH->RAM. This is mostly from brcm47xx, just with u-boot image vs TRX partitions.

# This will pad given files to 64k boundaries to make a single u-boot image.

# we have to be fancy because u-boot mkimage is going to add 64 byte header, ...
