Subject: [PATCH 0/2] Add optional mtd nand alignment for subpage reading
Date: Thu, 6 Jan 2011 14:39:00 +1300 [thread overview]
Message-ID: <1294277942-1252-1-git-send-email-cdhmanning@gmail.com> (raw)
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
