This is the other layout I have for another ingenic device:
http://projects.qi-hardware.com/index.php/p/qi-kernel/source/tree/od-2011-09-18/arch/mips/jz4740/board-a320.c#L125
Page size and OOB size are the same between these two devices.
Indeed. Do you know if there are other kind of layouts in the wild?
I'm getting a new board in a few weeks, I'll be able to check that out.
Note that <layout-id> can be a string, so if each each board is
defining its own layout, you could specify the board name here.
Otherwise, if you just have those 2 patterns, you can just name them
"contiguous" and "interleaved".
I don't like the idea of adding board-specific data inside the driver...
I'd prefer to use the method I used in this patch, but inside the
jz4740-nand driver, if you're OK with it.
Thanks,
