From 5c71d6181f5c23c35415bddf1414f840e9149f8c Mon Sep 17 00:00:00 2001 From: Robert Tivy Date: Thu, 28 Mar 2013 18:41:46 -0700 Subject: ARM: davinci: da8xx: add remoteproc support Add remoteproc platform device for controlling the DSP on da8xx. The patch uses CMA-based reservation of physical memory block for DSP use. A new kernel command-line parameter has been added to allow boot-time specification of the physical memory block.
