Folks,
I sat down last night to blink my 7400's LEDs using a 2.4.26-ts11
module. I did what I've always done before with arm processors
ioremap_nocache with physical address then use readw and writew.
Nothing happened. Further investigation revealed inw/outw, IO_ADDRESS,
__ioremap approaches. When I wrote my book 6 years there was only
ioremap_*. Can someone explain why these other approaches have cropped
up over the years with 2.4?
Thanks,
Craig
