We certainly need this to operate as such:
- The SPI NOR driver knows what the SPI NOR flash can do (if it can do fast
read, quad read, ddr read ...)
- The SPI bus driver knows what types of transfer it can support
The SPI NOR driver shall then negotiate the best transfer option and use it. So
yes, we need flags to specify what each SPI NOR can do.
Best regards,
