+* Description:  This file includes BIOS emulator I/O and memory access
+*               functions.
+*
+*		Jason ported this file to u-boot to run the ATI video card
+*		BIOS in u-boot. Removed some emulate functions such as the
+*		timer port access. Made all the VGA port except reading 0x3c3
+*		be emulated. Seems like reading 0x3c3 should return the high
+*		16 bit of the io port.
