[U-Boot] Regarding NAND flash support in IMX31

[R Arun Kumar]

Hai

I am trying to port U-boot 2.0.0  for my custom imx31 board and I am able to
boot and load linux etc successfully.

I want to add NAND flash support and it is observed that the NAND flash is
been detected but with lot of "Bad erase block messages"

Please help

Arun
