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

The Linux FlexSPI driver for the i.MX8 processors still uses the IP commands for FlexSPI flash memory writes since this is more efficient and deterministic way of performing FlexSPI flash memory writes.


Have a great day,
