Hi Jagan,
I cannot find any information on this board online, so I am guessing
it has not been released yet and you are developing software support
now.
Do you have any datasheet/overview document of the board?
Rather than making a lot of noise on the various MLs, why not wait
until all hardware has a driver written for it & bugs have been been
smashed, then patch in one series?
