From b8b4bb0745b63e03eec745ce0eb97bfa6e0792a1 Mon Sep 17 00:00:00 2001 From: Dean Glazeski Date: Thu, 17 Dec 2009 21:02:39 -0600 Subject: NAND read data page refactor. Added a new function to encapsulate reading a page of data from a NAND device using either the read_block_data function of a NAND controller or to use direct reading of data from the NAND device. This also adds some performance enhancements and uses the read_data function if the read_block_data function fails safely (because it can't allocate a buffer in the working area).
