The Inter-VM communication (IVC) is a communication protocol which is
designed for interprocessor communication (IPC) or the communication
between the hypervisor and the virtual machine with a guest OS.

Message channels are used to communicate between processors. They are
backed by DRAM or SRAM, so care must be taken to maintain coherence of
data.

The IVC library maintains memory-based descriptors for the transmission
and reception channels as well as the data coherence of the counter and
payload. Clients, such as the driver for the BPMP firmware, can use the
library to exchange messages with remote processors.

Based on work by Peter Newman [off-list ref] and Joseph Lo
[off-list ref].

All the renaming/restructuring relative to the internal code made 
comparing them a bit more difficult that I'd like...
