void gpmc_cs_config	(	char	cs,
		struct gpmc_config *	config
	)

Configuration for a specific chip select.

Configuration for a specific chip select.

Parameters:

	cs	chip select index
	config	gpmc_config structure describing the CS params

Returns:

void

void gpmc_generic_init

(

unsigned int

cfg

)

Generic configuration - will reset all the cs configs.

Generic configuration - will reset all the cs configs.

if you choose otherwise, Use gpmc registers to modify the values. The defaults configured are: No idle, L3 free running, no timeout and no IRQs. we allow for gpmc_config data to be programmed, and will also disable ALL CS configurations

Parameters:

cfg

- GPMC_CFG register value

Returns:
