Hello Scott,
From: Gupta, Pekon Subject: [PATCH v9 0/4] mtd: nand: omap: optimize OMAP NAND driver
OMAP NAND drivers support various ecc-schemes like (HAM1, BCH4, BCH8..) And, each ecc-scheme usually has 2 implementations
- HAM1_HW or BCHx_HW (using in-build h/w engine for all computation)
- HAM1_SW or BCHx_HW_DETECTION_SW) (using software library for some computation)
This patch series is Part-2 (split) from earlier series, as mentioned below: http://lists.denx.de/pipermail/u-boot/2013-November/167270.html
This series aims at following:
- cleans-up redundant code, duplicate in different ecc-schemes
- optimizes ecc calculation and correction paths
- improves scalability and readability, for adding newer ecc-schemes in future.
- updates following callbacks for different ecc-schmes:
[PATCH 1/4] nand_chip->ecc.hwctl(): configures h/w controller before for Read/Write acccess [PATCH 2/4] nand_chip->ecc.calculate(): calculates and fetches ECC syndrome from h/w controller. [PATCH 3/4] nand_chip->ecc.correct(): detects and corrects ECC errors on read access [PATCH 4/4] update doc and README
*changes in v9*
- split from main series, rebased and forked independently
Request you to please review this series. And accept it if it looks okay.
And a bug-fix which causes regression for x8 NAND devices using HAM1 ecc-scheme. This was reported & (un-officially) tested by Stefan Roese sr@denx.de.
with regards, pekon
