1 | /* include/asm-ppc/mpc8260_pci9.h |
2 | * | |
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. | |
