Ok,I will add them for our Micron spi nor.

Yes, I have tested my patch based on latest linux kernel ,the spi nor are just our Micron spi nor,
such as 45nm MT25QL256Mb and Mt25TL245Mb.Before submitting a patch, our team will review and test it.
only past testing and confirm OK,this patch can be submitted.
