Good idea!

Sorry, but the U-Boot ASH405 target is an "esd" custom board (PPC405EP
based) and _not_ the IBM Ash Eval Board! :-(.

I am afraid, but the IBM Ash Eval Board is not supported (to my
knowledge) right now. I don't think, that a NPe405h target is supported
at all. This should not be so hard starting from the PPC405GP.
