#     powerpc/iomap: inline generic io accessors
#     
#     ioreadXX[be]() and iowriteXX[be]() are doing the same things as the
#     powerpc specific in_[be]XX() and out_[be]XX() accessors, but they
#     are not inlined.
#     
#     There are some work in progress to replace the powerpc specific
#     functions in Quicc Engine driver by generic code in order to allow
#     QE to be used also on ARM.
#     
#     In order to keep performant IO accesses, generic io accessors need to
#     be inlined. This avoids calls of tiny functions that require setting
#     up stack frames and saving volatile registers, all this often taking
#     more CPU time than the work performed by the IO accessor itself.
#     
#     The string functions ioreadXX_rep() and iowriteXX_rep() also get
#     inlined as they are only trampolines to readsX() and writesX() outline
#     functions.
