For the u-boot-with-spl.bin target to be useful for the AST2600, set the maximum SPL size which also sets the padding length.
The normal way of loading u-boot is as a FIT, so configure u-boot.img as the SPL playload.
With this the following simple steps can be used to build and boot a system:
make u-boot-with-spl.bin truncate -s 64M u-boot-with-spl.bin qemu-system-arm -nographic -M ast2600-evb \ -drive file=u-boot-with-spl.bin,if=mtd,format=raw
