AHB write over flexSPI

I'm looking at the linux driver for flexspi, fsl-flexspi.c and I'm working with an iMX8.   The reference manual states the following:  Memory mapped read/write access by AHB Bus.   However, the driver does memory mapped reads, it's still using the IP commands and TFDR register for writes.   

 

 Anyone know what this is the case?

 

thanks,

jeff
