>    And these are the patches required to address the following input -
>      1. The NAND driver needs to stop tinkering with the GPMC registers
> 	The omap General Purpose Memory Controller (GPMC) registers are omap
>         specific, and not driver specific. Tinkering with these registers can
>         cause issues with the other devices on the GPMC.
> 
>      2. Passing hardcoded GPMC_CS0_BASE needs to go from the board files
> 	Passing hardcoded GPMC virtual addressess is sure way to mess up things.
>         This should all become unnecessary once the NAND drivers stops messing
>         with the GPMC registers directly.

Thanks, I'll add this series into omap-for-linus.

Regards,

Tony
