[PATCH v2 5/7] ast2600: Configure u-boot-with-spl.bin target

[Joel Stanley]

The normal way of loading u-boot is as a FIT, so configure u-boot.img as
the SPL playload.

The u-boot-with-spl.bin target will add padding according to
CONFIG_SPL_MAX_SIZE which defaults to 64KB on the AST2600.

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
