Exactly how do I accomplish that?

I can see how I can move the LCD between slave DDR port 2 and 3 by
selecting LCDC DMA master 8 or 9 (but according to the above it should
not matter). The big question is how I control what slave the NAND flash
is going to use? I find nothing in the datasheet, and the code is also
non-transparent enough for me to figure it out by myself without
throwing out this question first...

Cheers,
Peter
