Subject: [PATCH 0/2] [MTD] [NAND] Add prefetch and dma support for omap2/3  
              NAND      driver

Hi,

I have splited gpmc prefetch support for NAND into two patches:
[PATCH 1:2] : Adding support for nand prefetch-read and post-write, in MPU mode.
[PATCH 2:2] : Adding DMA mode support in nand prefetch/post-write

These patches implements Tony's comments. (For comments and discussion see:
http://lists.infradead.org/pipermail/linux-mtd/2009-June/025993.html)

Other than that, gpmc_prefetch_(inti/request) call has been removed, as nothing
great was done in that and we really do not need that.

Function 'gpmc_prefetch_enable' does check for 'if prefetch is already being
used by some other driver?'. And if it is busy, normal cpu copy method for
read/write request will be used.

Thanks and regards,
vimal
