RISC microcontrolers for efi

[Clinton L. Corbin]

Folks,
	Just wandering if anyone has looked at he newer PowerPC based
microcontrollers from Motorola and IBM.  How well would they work for a efi
application?  It appears that both companys are pushing (and supporting) these
chips pretty hard.  Anything that would make them very difficult (or very
expensive) to use an efi application?  How good are the supporting chips? 
Any comments?
