   At last. Cool. I know this SoC has IDE controller. Planning on 
submitting a driver?

Yes, but I'm wondering whether it is worth to submit before converting
to ata driver.  It seems the drivers/ide in in deep
cleanup/refactoring state.  (linux-next contains 100 patches from
Bartlomiej!)

Do you think a new ide driver will be accepted?

   I myself have the source (outdated and needing a big hammer) and even 
the documentaion AFAIR but lack both the hardware (at least locally 
accessible) and time.

   Well,  IDE is still more embedded friendly (not coupled with SCSI -- 
unlike libata)...

   Of course it will. But due to much of refactoring that's been 
happening it will require some work to move it forward from the older 
version (I guess you have it as well): IDE drivers should now be pretty 
close to the libata ones functionally.

I have a driver for current mainline and it is based on the driver in
CELF patch archive.  I will try to update the driver against
linux-next tree.
