Yes, now there is quite a mess with dataflash only setup.
I was able to do "exclusive dataflash binary for u-boot" by adding
necessary defines from flash.h to dataflash.h (these changes where
included in patch I sent):
------------------------------------------------
#define ERR_OK                         0
#define ERR_TIMOUT                     1
#define ERR_NOT_ERASED                 2
#define ERR_PROTECTED                  4
#define ERR_INVAL                      8
#define ERR_ALIGN                      16
#define ERR_UNKNOWN_FLASH_VENDOR       32
#define ERR_UNKNOWN_FLASH_TYPE         64
#define ERR_PROG_ERROR                 128
/*
 * Protection Flags for flash_protect():
 */
#define FLAG_PROTECT_SET       0x01
#define FLAG_PROTECT_CLEAR     0x02
------------------------------------------------

and removing flash related commands such as CFG_CMD_FLASH CFG_CMD_IMLS
from board config. It was just quick workaround.
