Hi Tom,

Resending this since I got no replies on the first version. I also fixed up the commit log of #1.

Sorry, I intended to play with it, but got busy.

No problem. I just don't want it to get lost.

Can you do a v3 where
you also enable this on am335x_evm which is where I assume you did, or at least can, test the code? Thanks!

No, I only successfully tested this on an own board implementation. I didn't know whether am335x_evm has 8-bit or 16-bit NAND. I didn't touch the config of any board I don't have access to as I can't test such a change :)

Can you just add

  #define CONFIG_NAND_OMAP_GPMC_PREFETCH

in your config and commit it with your S-o-b if it works for you?

Thanks,
Daniel
