Hi All,

I'm looking for information on how to access a Compact Flash card which is
memory-mapped (from 0x20001000)

>From what I have read, there a 3 address lines (8 addresses) which access
IDE registers within the CF chip

My question is, how do I access such a custom address range within Linux?

I'm looking at the 'OF-platform PATA driver' which appears to be what I
want (a very basic IDE driver) but I am a bit lost on how to set up a
specific base address.

Where should I look for examples of CF cards mapped to specific address spaces?

TIA

Graeme
