I'm not sure about NCR53c90, but the Am53c94/53c96 manual is:

BTW, we already have MI ncr53c9x driver under sys/dev/ic/ and
I think 53c90 is equivarent for ESP100.
(it lacks sync ops and SELATN3 command etc.)

Maybe all you have to do to support ncr53c90 MCA SCSI is
to implement glue functions including DMA stuff.
(like dev/pci/pcscp.c)
