Subject: [PATCH 0/4] mtd: nand: OMAP: Add support to use ELM as error correction module
Date: Wed, 3 Oct 2012 19:59:45 +0530 [thread overview]
Message-ID: <1349274589-11389-1-git-send-email-avinashphilip@ti.com> (raw)
Adds support to use ELM as BCH 4 & 8 bit error correction module and
adds support for single shot read_page and write_page functions
Platforms containing the ELM module can be used to correct errors
reported by BCH 4, 8 & 16 bit ECC scheme. For now only 4 & 8 bit
support is added.
BCH 4 & 8 bit error detection support is already available in mainline
kernel and works with software error correction.
This series is based on top of [1] &[2]
1. linux-next/master
2. linux-omap-dt/for_3.7/dts_part2
Nand driver tested for BCH 4 & 8 bit error correction per sector.
This being tested by introducing bit errors at multiple sectors inside page.
