[U-Boot] [PATCH v4 0/5] mtd: nand: omap: optimize and clean-up of OMAP NAND driver

[Pekon Gupta]

*changes in v4*
[PATCH 1/5]
	- removed omap_read_page_bch(): chip->ecc.read_page uses default API
		nand_read_page_hwecc() in nand_base.c
	- updated tricorder.h: added new CONFIGS for ECCSCHEME & ONFI_DETECTION
	- converted printf("ECC-SCHEME") to debug("ECC-SCHEME")
[PATCH 2/5] minor code clean-up
[PATCH 3/5] <no update>
[PATCH 4/5] <no update>
[PATCH 5/5] updated README as per feedbacks from trini at ti.com

*changes in v3*
[PATCH 1/5] (complete change) 
	- ecc-scheme is selection is controller by s/w, not CONFIG_NAND_xx
	- added omap_select_ecc_scheme(), as common function to handle all
	  ecc-scheme related configurations for both board_nand_init() &
	  omap_nand_switch_ecc().
	- removed un-used defines from asm/arch-am33xx/omap_gpmc.h
	- updated doc/REAME.nand
[PATCH 2/5] removed un-used defines from asm/omap_gpmc.h
[PATCH 3/5] removed omap_calculate_ecc_bch_sw() and omap_calculate_ecc()
		and merged their logic into omap_calculate_ecc_bch()
[PATCH 4/5] updated return error-code in-case of invalid conditions
[PATCH 5/5] (new) for board/ti/am335x/README

*changes in v2*
- added documentation for CONFIG_NAND_OMAP_xx in doc/README.nand
- added CONFIG_BCH along with CONFIG_NAND_OMAP_ECC_BCH8_CODE_HW_DETECTION_SW
  to include software library lib/bch.c
- fixed board_nand_init() and omap_enable_hwecc()

*original v1*
This patch series updates BCH8_ECC schemes in mtd/nand/omap_gpmc.c driver
- adds scalability for higher ECC schemes in future.
- removes CONFIG_AM335x and it makes it generic for all platforms.
- optimizes read_data paths
