- * 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.
