f8650efa3f Preliminary work on new bootloader using new SD peripheral. 
Rewrote copyflash to take advantage of the new peripheral. The new
peripheral has the neat ability to use CMD18 in the SD card
specification, allowing us to load multiple blocks in succession,
ending the chain of CMD18 commands with a CMD17.
