/*
* Operations which handle byte stream data on word access.
*
* These functions are defined to resolve endian mismatch, by either
* - When normal (i.e. stream-less) operations perform byte swap
* to resolve endian mismatch, these functions bypass the byte swap.
* or
* - When bus bridge performs automatic byte swap, these functions
* perform byte swap once more, to cancel the bridge's behavior.
*
* Currently these are just same as normal operations, since all
* supported buses are same endian with CPU (i.e. little-endian).
