Sorry, I had missed this question before.
RZ/G3E SMARC EVK (which shares the same carrier board) has it enabled,
too, as the connector is labelled "Type-2A", i.e. meant for expanded
SPI.  Obviously it really depends on the use case: one might want to
use the pins as GPIOs?  We can revisit this when we get real connector
support.
