bool "Support OMAP GPMC NAND controller"

help
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_GPMC_PREFETCH
bool "Enable GPMC Prefetch"

help
On OMAP platforms that use the GPMC controller

uses the prefetch mode to speed up read operations.
config NAND_OMAP_ELM
bool "Enable ELM driver for OMAPxx and AMxx platforms."
depends on NAND_OMAP_GPMC && !OMAP34XX
help
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.
