static struct nand_device* get_nand_device_by_name ( const char * name )

static

Returns the flash bank specified by name, which matches the driver name and a suffix (option) specify the driver-specific bank number.

The suffix consists of the '.' and the driver-specific bank number: when two davinci banks are defined, then 'davinci.1' refers to the second (e.g. DM355EVM).
