It must have been the MIPS Technologies' Atlas development board which
has a SYM53C810A incorporated, even though the resulting changes are
specific to the board. There appears to have been some sort of confusion
about the semantics of i/o and mmio operations in mixed-endian
configurations, which for the MIPS port actually is currently being

I can verify whether the other driver operates correctly in the four
possible configurations with an Atlas board.
BTW, that SCSI_NCR_BIG_ENDIAN macro looks scary -- is the chip wired
incorrectly (i.e. with byte lanes swapped at PCI) or are i/o and/or mmio
operations simply broken for parisc?

It looks like some sort of a merging mistake.
