/* * Sane hardware offers swapping of PCI/ISA I/O space accesses in hardware; * less sane hardware forces software to fiddle with this... * * Regardless, if the host bus endianness mismatches that of PCI/ISA, then * you can't have the numerical value of data and byte addresses within * multibyte quantities both preserved at the same time. Hence two * variations of functions: non-prefixed ones that preserve the value * and prefixed ones that preserve byte addresses. The latters are * typically used for moving raw data between a peripheral and memory (cf. * string I/O functions), hence the "__mem_" prefix.
