Hi All,
I finally got the FLASH controller driver working and it is now successfully
reporting the presence of 2GB Flash in the board. I used the new "libata"
driver code present in the new kernel source under drivers/ata/. Also did
the required additions in the device tree to provide the IO port, IRQ and
PIO mode details to the driver.
However now I am getting the below errors.

Can anyone suggest why I am getting the above errors?
Thanks,
