I tested on LS1043AQDS board based on your spi-nor branch. The 'spi_flash_probe'
failed during QSPI boot. Then I found that CONFIG_DM_MTD_SPI_NOR is not defined
for the board but it could be selected if CONFIG_MTD && CONFIG_DM_SPI, correct? 

So after I moved CONFIG_MTD to the defconfig file, the probing could work now.

And there is another small effect on our Fman driver. It would like to read ucode blob 
from the QSPI flash. As the 'spi_flash_read' interface is changed, I've modified the address
value to an offset value in flash.
