After thinking twice, I realized that the most convenient way for me is
adding an option to get rid of the mess of logic PIO. MIPS system is emulating
x86's behavior, while logic PIO isn't designed for such platform.
Or probably I need a variation of Logic PIO, which leave MMIO space AS-IS
(not try to reallocate it)
but still preserving higher 0x4000 for indirect access.
Thanks a lot!
