[PATCH v4 0/4] optimize and clean-up of OMAP NAND and ELM driver

[Pekon Gupta]

*changes from v3* (feedbacks from Brian Norris <computersforpeace at gmail.com>)
[PATCH 2/4] reverted back macros used for clearing & masking gpmc_ecc_config reg
[PATCH 4/4]
- updated: using 'pr_fmt(fmt)' to suffix DRIVER_NAME to error messages
- removed: local 'eccsteps' in ELM driver, instead using nand_chip->ecc.steps
- cleanup: consitent use of DRIVER_NAME and removed irrelavant white-space changes


*changes from v2 (rebased)*
- rebased on [PATCH v11] mtd:nand:omap2: clean-up of supported ECC schemes
http://lists.infradead.org/pipermail/linux-mtd/2013-October/049410.html


*changes from v1 (minor)*
- rebased for newer version of previous patch-set
	[PATCH v7 0/6] mtd:nand:omap2: clean-up of supported ECC schemes
	http://lists.infradead.org/pipermail/linux-mtd/2013-October/048983.html
- code cleanup and formating updates

*original v1*
This patch series builds the base for adding support for newer H/W based ECC
schemes for NAND flash. This patch series 
- cleans-up redundant code among various
- optimizes ecc calculation and correction paths
- improves scalability and readability, for adding newer ecc-schemes in future.
This patch affects following data-paths: 
[PATCH 1/4] nand_chip->ecc.correct(): Detects and corrects ECC errors on read accesses.
[PATCH 2/4] nand_chip->ecc.calculate(): Calculates and fetches ECC syndrome from controller.
[PATCH 3/4] nand_chip->ecc.hwctl(): Configures H/W controller for Read/Write data acccesses.
[PATCH 4/4] ELM driver: add checks and updates code for scalability.

Pekon Gupta (4):
  mtd: nand: omap: optimized chip->ecc.correct() for H/W ECC schemes
  mtd: nand: omap: optimize chip->ecc.calculate() for H/W ECC schemes
  mtd: nand: omap: optimize chip->ecc.hwctl() for H/W ECC schemes
  mtd: devices: elm: add checks ELM H/W constrains, driver code cleanup
