Generic nand and DOC

Generic nand and DOC

[Carlos, John J USAATC]

Hi All,

  I have been trying to get my DOC Mil plus to work properly.  The code in
the devices dir that is M-sys specific seems to works for the chip but I
can't use nandwrite on the chip.  Am I to assume from the lists that the
goal is to stop using the code in the devices directory and use the generic
nand/inftl stuff to work for all devices?  The code for DoC_IdentChip is
very specific, is it the plan that nand_scan will replace the later?

  I have been taking time to try to understand the workings of the drivers
and want to make sure I have the correct big picture.

Thanks,
John

The plan is to have a doc driver in drivers/mtd/nand which uses the generic 
nand code and overrides the doc specific functions. On top of this (I)NFTL 
can be used or JFFS2/YAFFS without the (I)NFTL layer.

Dan Brown is actually working on it.

No, this will be part of the doc driver in drivers/mtd/nand
