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 resolved. > sym53c8xx_defs.h is only used for the ncr53c8xx driver, which despite > the name is only for NCR53c720 chips these days (supported on parisc, > and eisa/mca). It has correct big endian support for parisc alrady. 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? > Also the patch duplicates your changelog and copyright entry that's > in the file already. It looks like some sort of a merging mistake. Maciej
