Flashing U-Boot using DediProg(R) on Aspeed AST2500 EVB

[Rick Altherr]

Xo and I have been using SF100s with AST2500 EVB.  It works OK.  The main
gotcha seems to be that after writing to the flash with the SF100, it is
left in a state that the AST2500 can't seem to boot from.  Power cycling
fixes it.  I haven't spent the time to investigate further.
