* 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.
