This patch adds support for a generic spinand framework(spinand_mtd.c).
This frameowrk can be used for other spi based flash devices also. The idea
is to have a common model under drivers/mtd, as also present for other no spi
devices(there is a generic framework and device part simply attaches itself to it.)
The generic frework will be used later by me for a SPI based spansion S25FL256 device.
The patch also contains a micron driver attaching itself to generic framework.

I am working on Micron SPINAND(Micron MT29F1G01ZACH). I tried this patch, but it's not working.
It is throwing following error message while mounting:
[ 260.232000] jffs2: cannot read OOB for EB at 00000000, requested 8 bytes, read 0 bytes, error -22
mount: mounting /dev/mtdblock5 on /mnt/ failed: Input/output error
I am working on it to fix into the driver, will send an updated patch with the fix.
Thanks for replying on this.
Since, this patch is already posted, I think it will be better if you post
the delta fix on top of this patch.
Thanks,
Kamlakant Patel
