Please convert your driver even if you don't need the extra
flexibility, so that one day we can eliminate the old mechanism.
CONFIG_SYS_NAND_ONFI_DETECTION
Enables detection of ONFI compliant devices during probe.
And fetching device parameters flashed on device, by parsing
ONFI parameter page.
CONFIG_BCH
Enables software based BCH ECC algorithm present in lib/bch.c
This is used by SoC platforms which do not have built-in ELM
hardware engine required for BCH ECC correction.
Platform specific options
=========================
CONFIG_NAND_OMAP_GPMC
Enables omap_gpmc.c driver for OMAPx and AMxxxx platforms.
GPMC controller is used for parallel NAND flash devices, and can
do ECC calculation (not ECC error detection) for HAM1, BCH4, BCH8
and BCH16 ECC algorithms.
CONFIG_NAND_OMAP_ELM
Enables omap_elm.c driver for OMAPx and AMxxxx platforms.
ELM controller is used for ECC error detection (not ECC calculation)
of BCH4, BCH8 and BCH16 ECC algorithms.
Some legacy platforms like OMAP3xx do not have in-built ELM h/w engine,
thus such SoC platforms need to depend on software library for ECC error
detection. However ECC calculation on such plaforms would still be
done by GPMC controller.
CONFIG_NAND_OMAP_ECCSCHEME
On OMAP platforms, this CONFIG specifies NAND ECC scheme.
It can take following values:
OMAP_ECC_HAM1_CODE_SW
1-bit Hamming code using software lib.
(for legacy devices only)
OMAP_ECC_HAM1_CODE_HW
1-bit Hamming code using GPMC hardware.
(for legacy devices only)
OMAP_ECC_BCH4_CODE_HW_DETECTION_SW
4-bit BCH code (unsupported)
OMAP_ECC_BCH4_CODE_HW
4-bit BCH code (unsupported)
OMAP_ECC_BCH8_CODE_HW_DETECTION_SW
8-bit BCH code with
- ecc calculation using GPMC hardware engine,
- error detection using software library.
- requires CONFIG_BCH to enable software BCH library
(For legacy device which do not have ELM h/w engine)
OMAP_ECC_BCH8_CODE_HW
8-bit BCH code with
- ecc calculation using GPMC hardware engine,
- error detection using ELM hardware engine.

To enable hardware assisted BCH8 (8-bit BCH [Bose, Chaudhuri, Hocquenghem]) on
OMAP3 devices we can use the BCH library in lib/bch.c. To do so add CONFIG_BCH

syndrom generation to your board config.
and set CONFIG_NAND_OMAP_ECCSCHEME=5 (refer README.nand) for selecting BCH8_SW.
The NAND OOB layout is the same as in linux kernel, if the linux kernel BCH8
implementation for OMAP3 works for you so the u-boot version should also.
