OTOH, CF support via self-contained driver is certainly a waste of code since IDE core and (libata) are here to drive the CF devices as well. What we need is a "normal" IDE or libata (at your option) driver.
A libata driver would be nice and probably easiest to do as you don't
have to pretend to be close to old style taskfile IDE for a PC.
I am not convinced there is no case for a 'dumb' small CF driver, but if
so the chipset code and the core code need to be separated as the other
requests I see for this are different embedded boxes wanting to keep
codesize down.
