   3  * Undefine the PCI read* and in* macros so we can define them as functions
   4  * that implement the workaround for the MPC8260 device erratum PCI 9.
   5  *
   6  * This header file should only be included at the end of include/asm-ppc/io.h
   7  * and never included directly anywhere else.
