[PATCH] microblaze: Provide pgprot_device/writecombine macros for nommu

From: Michal Simek
Date: Fri Feb 23 2018 - 04:21:22 EST


These macros are required for generic mmap.c implementation created by:
commit f719582435af ("PCI: Add pci_mmap_resource_range() and use it for
ARM64") which Microblaze is going to use.
