Last change on this file since 100626 was 100185, checked in by vboxsync, 18 months ago

Devices/VMMDev: Add an MMIO interface in addition to the existing PIO interface for guest additions running inside an ARM based guest. Also remove the dependency from the architecture page size and introduce a 4KiB VMM page size as ARM has different page sizes (4KiB, 16KiB, 64KiB) and it can differ between host and guest, bugref:10456
