14 Mailboxes

The mailboxes provided by the PCI bridge chip allow the host and the Root DSP
to send signals to each other.
Note that mailboxes are intended as a signalling mechanism and not as a way of
passing large amounts of data.
The V3 bridge chip provides 16 x 8-bit mailboxes, which are combined to form
two independent 32-bit, bi-directional mailboxes numbered 0 and 1.
