I getting ready to quote a customer on a board we are developing that will use a ep9312 system-on-chip.

I'm going to need to use it's IDE interface, is support for this currently available in u-boot?

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): http://www.freelists.org/archives/linux-cirrus/04-2005/

We will also need to be able to read/write a fat parition is this supported?

I see configuration options for both, but no direct hardware support for the 9312 hardware, am I missing it?

The patch for 1.1.2 is at: http://www.dave-tech.it/download/misc/sw/edb93xx/u-boot-edb93xx-3
