Maps a memory region in the device address space. Identical to Linux driver pretty much.
Maps a memory region in the device address space.
Unaligned size will cause a [[#Panic]].
On success, the mapped memory region is granted the [[SVC#MemoryAttribute|DeviceShared]] attribute.
On success, the mapped memory region is granted the [[SVC#MemoryAttribute|DeviceShared]] attribute.

Maps a memory region in the device address space with extra params.
Unaligned size will cause a [[#Panic]].
