mtd: nand: omap: combine different flavours of 1-bit hamming ecc schemes
OMAP NAND driver currently supports multiple flavours of 1-bit Hamming
ecc-scheme, like:
- OMAP_ECC_HAMMING_CODE_DEFAULT
1-bit hamming ecc code using software library
- OMAP_ECC_HAMMING_CODE_HW
1-bit hamming ecc-code using GPMC h/w engine
- OMAP_ECC_HAMMING_CODE_HW_ROMCODE
1-bit hamming ecc-code using GPMC h/w engin with ecc-layout compatible
to ROM code.
This patch combines above multiple ecc-schemes into single implementation:
- OMAP_ECC_HAM1_CODE_HW
1-bit hamming ecc-code using GPMC h/w engine with ROM-code compatible
ecc-layout.
