From 221838cc7eb178370ff62aa05920a582e12ac322 Mon Sep 17 00:00:00 2001 From: Jason Jin Date: Tue, 10 Jul 2007 09:03:22 +0800 Subject: 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.
