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.
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.
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.
