Yes, it is not changed.

I will protect prototype and implementation, but I prefer to not move
the code in da8xxevm/common.x. The ea20 board has its own directory, and
the place to share code among all davinci boards is under davinci/common
instead of under da8xxevm. And probably it should be better to protect
the function with CONFIG_SOC_DA8XX, too.

The main reason is that I cannot test at the moment the NAND. I think
the best way to do is that I will provide another patch only when I will
get a new release of the board and I can test the NAND functionalities.
At the moment, this is dead code.

Yes, I noted too late, email was already sent ;-)
