commit 221838cc7eb178370ff62aa05920a582e12ac322
Author: Jason Jin <Jason.jin@freescale.com>
Date: Tue Jul 10 09:03:22 2007 +0800
Remove the bios emulator from MAI board.
The bios emulator in the MAI board can not pass compile
and have a lot of crap in it. remove it and will have a
clean and small bios emulator in the drivers directory
which can be uesed for every board.
