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!
