| | | | | | | | | | | | | | | | | | | | The definitions for the PC-style PIO functions in asm-generic/io.h were meant as dummies so you could compile code on architectures without ISA and PCI buses. However, unicore32 actually wants to use them with a real PCI bus, so they need to be defined to actually address the register window holding the I/O ports.
