Some remote processors (in particular the modem) found in Qualcomm platforms
stores configuration parameters and other data in a file system. As the remotes
does not have direct storage access it needs to relay block accesses through a
service running on the application CPU.
The memory is described in DeviceTree by a new reserved-memory compatible and
the implementation provides the user space service a read/write interface to
this chunk of memory.
