In order to save IRQ lines, current platforms have been only been given a single interrupt for receiving messages from co-processors. The best way to work around this limitation is to use Mailbox 1 (A9) as the receiving MB. This driver/binding then has the ability to map the remaining Mailboxes back to Mailbox 1 where threaded interrupts are used to extract data to send back to the user.
