hw/ppc/ppc405_uc: Convert away from old_mmio
Convert the devices in ppc405_uc away from using the old_mmio MemoryRegion accessors: * opba's 32-bit and 16-bit accessors were just calling the 8-bit accessors and assembling a big-endian order number, which we can do by setting the .impl.max_access_size to 1 and the endianness to DEVICE_BIG_ENDIAN, and letting the core memory code do the assembly * ppc405_gpio's accessors were all just stubs * ppc4xx_gpt's 8-bit and 16-bit accessors were treating the access as invalid, which we can do by setting the .valid.min_access_size and .valid.max_access_size fields Signed-off-by: Peter Maydell <peter.maydell@linaro.org> Reviewed-by: Philippe Mathieu-Daudé <f4bug@amsat.org> Signed-off-by: David Gibson <david@gibson.dropbear.id.au>master
