17 * Sane hardware offers swapping of PCI/ISA I/O space accesses in hardware;
18 * less sane hardware forces software to fiddle with this...
19 *
20 * Regardless, if the host bus endianness mismatches that of PCI/ISA, then
21 * you can't have the numerical value of data and byte addresses within
22 * multibyte quantities both preserved at the same time. Hence two
23 * variations of functions: non-prefixed ones that preserve the value
24 * and prefixed ones that preserve byte addresses. The latters are
25 * typically used for moving raw data between a peripheral and memory (cf.
26 * string I/O functions), hence the "__mem_" prefix.
