This reverts commit 82613b0da622efbd24cb7b23eb349966802310f1, because
commit daa0f15 (mtd: don't use __exit_p to wrap mxcnd_remove) is a
better solution. Not having a remove callback breaks rebinding because
resources are not freed on remove.

The existing NAND infrastructure allows the default main and
mirror bad block tables to be overridden in nand_default_bbt().
However, the davinci_nand driver does not support this. Add
that support by adding fields to the davinci driver's platform
data so platform code can pass in their own bbt's and make the
davinci_nand driver honor them.

Currently, the program and erase sequences do not wait for completion,
instead relying on a subsequent waitfunc() callback. However, this causes
the chipselect to be deasserted while the NAND chip is still asserting the
busy pin, which can corrupt activity on other chipselects.
This patch switches to using the sequences recommended by the manual,
in which a wait is performed within the initial command sequence. We can
now re-use the status byte from the initial command sequence, rather than
having to do another status read in the waitfunc.
Since we're already touching the command sequences, it also cleans up some
cruft in SEQIN that isn't needed since we cannot program partial pages
outside of OOB.

When a NAND operation is in progress, all other localbus operations
(including NOR flash) will have to wait for access to the bus. However, the
NAND operation may take longer to complete than the default timeout. Thus,
if NOR is accessed while a NAND operation is in progress, the NAND operation
will fail.

Add NAND_SCAN_SILENT_NODEV to chip->options to the user-worrying messages
'No NAND device found!!!'. This message often worries users (was three
exclamation marks really necessary?) and especially in systems such as the
Simtec Osiris where there may be optional NAND devices which are not
known until probe time.

by Artem Bityutskiy about adding a whole new call.

This is a quick and dirty patch to add panic_write for NAND flashes. The
patch seems to work OK on my CRIS board running a 2.6.26 kernel with a
ID: 0x20, Chip ID: 0xf1 (ST Micro NAND 128MiB 3,3V 8-bit), and also on a
OpenRD base (Marvell Kirkwood) board with a Toshiba NAND 512MiB 3,3V
8-bit flash with 2.6.32-pre1.

The NAND controller has some limitations how to access the
internal buffers. It only allows 32 bit accesses. The driver
used to work around this by having special alignment aware
copy routines.
We now copy the whole page to a buffer in memory and let the
access functions use this buffer. This simplifies the driver.
A bonnie++ test showed that this has no negative performance
impact on the driver.
