For the am3517 the only thing needed is to add SRAM
to the known memory. See [1], that should change the
cache misses (which likely cause the extra delays) to
actual caches. U-boot only adds the detected memory
and since U-boot is running from DRAM and SPL is not,
the difference seems obvious.

Jeroen
