There is no need to select CFI_FLASH if there is no CFI flash. The 
probing here is only because we want to display the size of parallel 
flash in initr_flash() of board_r.c.

Normally, devices are probed when they are used. You should be able to 
use "sf probe" for MTD uclass in the same way you do for SPI_FLASH uclass.

Best regards,
