Indeed, your driver is clear enough to serve as a doc. Looking at
ata_piix.c in 2.4, I see that the libata core has evolved a lot,
but backporting your work should not be hard at all. Among other
things, the driver needs to set ap->cbl itself during reset, for
instance.

However, I wonder if it's really worth doing it if the IDE generic
driver already works. The PATA port on such motherboards today is
mostly used by CD/DVD, and I think that even if we limit ourselves
to 40-pin, it's not dramatic (all my IDE CD drives have always been
running that way for ages).

Or maybe this would be more interesting for other chips of the same
family ?

Ivaylo, if you're interested in trying to backport pata_marvell.c
from 2.6 to 2.4, that's fine for me, just inform me so that I know
I'm waiting for you. Otherwise I can merge your IDE generic patch.
In this case, could you repost your patch after fixing the name
"MARVEL" in the PCI IDs (=> "MARVELL") ?

Thanks,
Willy
