The controller can be configured to disable or enable address and data byte lanes when issuing commands. This is useful in read command mode to send SPI NOR commands that don't have an address space, such as RDID. It's a good way to have a unified read operation for registers and flash contents accesses. A new SPI driver proposed by Aspeed makes use of this feature. Add support for address lanes to start with. We will do the same for the data lanes if they are controlled one day.
