Shouldn't this be selected by the SPI NOR driver instead ?
The same driver has other users, but they may not all want DIRMAP.
Why would they not want dirmap ?
There are currently 4 defconfigs which enable SPI_DIRMAP, three of them
are AST2x00 and one is imxrt1170-evk. I would be adding a 5th one.
Talk to Aspeed / NXP maintainers and ask them to test it.
However the same Cadence IP is used in many boards, including TI K3
am62a and am65, k3-j72xx, and also on Xilinx versal (based on looking at
compatible strings in devicetrees). None of these enable SPI_DIRMAP.
Talk to TI/Xilinx people too.
Lacking the hardware to test, I cannot say if enabling SPI_DIRMAP for
all users would cause problems. I would prefer not to take the risk.
You can do this in the SPI driver Kconfig entry:
select SPI_DIRMAP if ARCH_RZN1
