For the pblimage tool, the SPL image is splitted into 64 byte chunks,
and PBL needs a command for each piece. In current pblimage structure,
the size of the SPL image should be a fixed value. Well, for LS102xA
and some other ARM platforms, the size of the SPL image is changeable.
So a new image spl/u-boot-spl-pbl-pad.bin is built, and the size of
it is a fixed value "CONFIG_SPL_MAX_SIZE". Use it instead of
spl/u-boot-spl.bin for LS102xA.
CONFIG_SPL_PBL_PAD is used to enable this function.
