NAND doesn't need it because NAND goes through an API rather than direct memory-mapped access, and has more coarse-grained operations. NAND should be able to take care of this entirely in the driver using the select_chip() callback.
Fair enough. How do I enable that feature? Do I create my own board_nand_init() and then do this:
this->select_chip = p1022ds_nand_select_chip;
board_nand_init() is implemented in drivers/mtd/nand/fsl_elbc_nand.c. You'll need to add some board hook there.
Timur, is there any reason to use NOR rather than NAND with this chip?
Well, as with most of our boards, NOR is the default configuration. Also, there's no NAND support upstream yet.
What isn't upstream, besides the muxing hack? Does it need the 4K page hack?
