From: Hari Nagalla <hnaga...@ti.com> For each remote proc, reserve memory for IPC and bind the mailbox assignments. Two memory regions are reserved for each remote processor. The first region of 1MB of memory is used for Vring shared buffers and the second region is used as external memory to the remote processor for the resource table and for tracebuffer allocations.
