[PATCH 0/2] Add optional mtd nand alignment for subpage reading

[Charles Manning]

Subpage reading already provides a certain degree of alignment in that it
aligns the reads to 16-bits if the bus is 16-bits wide.

For some situations this is not enough. For eample, the OMAP2 prefetch
engine only works with u32 aligned buffers and read sizes.

This patch set adds a mechanism to plug in an alignment function and
provides an example using the omap2 nand driver.

Comments welcome
