I changed the _IO_BASE from 0x80000000 to 0xF0000000. I also set the
PBR1 of PCMCIA to 0xF0000000 and the IO space is 0x00~0x3f. When I use the
inw(x) to read or outw(x,y) to write the IO registers, it always return
"Segmentation fault". I guess my IO port address is not correct.
Should I set the MMU to make the 0xF0000000 to be the IO_PAGE? Thanks,
Leiying
