I know a recent change requires CONFIG_SYS_NS16550=y. I am not sure if DSPI
can/should be enabled. Let's wait for Alison/Prabhakar's comment on DSPI.

Alison/Prabhakar, DSPI support is enabled using DM for QDS and RDB for NOR boot.
Do we want to enable DSPI for nand boot, and secure boot?

Do you want to put this include inside ifdef? You have both ways in different
header files.
