Dave, We can add such support/enhancements later. The patch as such will work for sure.
OK, I can understand that. This board seems to have the most complex NAND config of the DaVinci EVMs.
In our LSPs we can use only one NAND at a time. We do not at this point of time have support even in the kernel where both NANDs can be used at the same time. Its only either of the 2.
And for that matter, even the DaVinci GIT tree doesn't yet support this board ... much less mainline Linux!
I believe the current NAND driver (in 2.6.30-rc) should handle this fine, though.

Thanks, Sandeep

So this initial U-Boot support only supports the smaller of the two NAND chips, and access to the second one is only after booting to the operating system?
I'd have liked to see the NAND driver updates needed to support the chipselect of the second NAND chip, and use it with HW ECC.
