Re: [PATCH 2/2] [POWERPC] MPC8349E-mITX: use platform IDE driver for CF interface

The hardware is called (E)IDE, the protocol is called ATA.
Or that's what I was told -- I think there's some historic
revisionism involved, too.

ATA is the interface and standards for the ANSI standards based disk
attachment. IDE "Integrated Drive Electronics" is a marketing name used
to cover all sorts of ST412 compatible-ish early interfaces that moved
the brains onto the disk. IDE doesn't really mean much but "brains on
disk", ATA is a real standard.

Thanks for refreshing my memory.

We will have to support both names in OF device tree nodes, since
both names are used in many existing device trees. For new nodes
with no precedent, like this "mmio-ide", let's require the more
correct "ata" name.
