There is an ep93xx u-boot patch against 1.1.2, but AFAIK it does not 
implement IDE.  It's the right place to start though if you want to 
implement the IDE support yourself.

No-one has taken the time yet to clean up the patch to make it 
acceptable for inclusion upstream, or to keep it up to date with latest 
u-boot CVS, but this is on the cards (Eric Bernard is hoping to do the 
work).

See the various u-boot threads on linux-cirrus from this April 
(including parts of the "redboot and kernel version" thread):
