how to use the isa emulator on the motorola mpc823 board

[邓永龙]

hi,

I am using the motorola mpc823 evaluation board and the linux kernel. I
want to connect with a isa card by the UPMB, that's the kernel's default
setting. I have read the bootloader code ,I found it has done all the
work that needed for using the isa emulator. Now, can I access the isa
address area in the kernel or moduler like this:(port size is 16 bit)

	unsigned short *p	0x06000000;		//BR4 = 0x060018C1
	*p = 0x55;
Do some know about it? Thank's very much for you help!
