[U-Boot-Users] ep9312 IDE support

[U-Boot-Users] ep9312 IDE support

[NZG]

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?

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?

thx,
NZG.

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):
