From 400e64df6b237eb36b127efd72000a2794f9eec1 Mon Sep 17 00:00:00 2001 From: Ohad Ben-Cohen Date: Thu, 20 Oct 2011 16:52:46 +0200 Subject: remoteproc: add framework for controlling remote processors Modern SoCs typically employ a central symmetric multiprocessing (SMP) application processor running Linux, with several other asymmetric multiprocessing (AMP) heterogeneous processors running different instances of operating system, whether Linux or any other flavor of real-time OS. Booting a remote processor in an AMP configuration typically involves: - Loading a firmware which contains the OS image - Allocating and providing it required system resources (e.g. memory) - Programming an IOMMU (when relevant) - Powering on the device This patch introduces a generic framework that allows drivers to do that. In the future, this framework will also include runtime power management and error recovery. Based on (but now quite far from) work done by Fernando Guzman Lugo . ELF loader was written by Mark Grosen , based on msm's Peripheral Image Loader (PIL) by Stephen Boyd . Designed with Brian Swetland .
