Subject: [RFC PATCH 0/2] mtd: nand: add manafacturer specific handling

Hello,

This is a proposal to add support for manufacturer specific handling of
NAND chips.

Currently the only ones allowed to modify how NAND chips are accessed are
NAND controllers (by modifying the nand_chip callbacks) and NAND core code
(by setting default callbacks when these are not specified by the NAND
controller).

This series adds support for manufacturer/vendor specific handling, which is
particularly useful for read retry implementation that are (at least for
the moment) manufacturer specific.

I know there was a debate on how we should support all these READ RETRY
implementations (see http://permalink.gmane.org/gmane.linux.drivers.mtd/50603),
so please tell if I'm wrong.

Best Regards,

Boris
