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
<fernando.lugo@ti.com>.
ELF loader was written by Mark Grosen <mgrosen@ti.com>, based on
msm's Peripheral Image Loader (PIL) by Stephen Boyd <sboyd@codeaurora.org>.
