* This structure communicates platform-specific information to the GPMI NAND
|

|
* @platform_init: A pointer to a function the driver will call to
|

* initialize the platform (e.g., set up the pin mux).
|

* @min_prop_delay_in_ns: Minimum propagation delay of GPMI signals to and
|
|
* from the NAND Flash device, in nanoseconds.
|
|
* @max_prop_delay_in_ns: Maximum propagation delay of GPMI signals to and
|
|
* from the NAND Flash device, in nanoseconds.
|
|
* @max_chip_count: The maximum number of chips for which the driver
|
|
* should configure the hardware. This value most
|
|
* likely reflects the number of pins that are
|
|
* connected to a NAND Flash device. If this is
|
|
* greater than the SoC hardware can support, the
|
|
* driver will print a message and fail to initialize.
|
|
* @partitions: An optional pointer to an array of partition
|
|
* descriptions.
|
|
* @partition_count: The number of elements in the partitions array.
