> 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
