Suman Anna e88bb8f7a1 remoteproc/keystone: Add a remoteproc driver for Keystone 2 DSPs
The Texas Instrument's Keystone 2 family of SoCs has 1 or more
TMS320C66x DSP Core Subsystems (C66x CorePacs). Each subsystem has
a C66x Fixed/Floating-Point DSP Core, with 32KB of L1P and L1D SRAMs,
that can be configured and partitioned as either RAM and/or Cache,
and 1 MB of L2 SRAM. The CorePac also includes an Internal DMA (IDMA),
External Memory Controller (EMC), Extended Memory Controller (XMC)
with a Memory Protection and Address Extension (MPAX) unit, a Bandwidth
Management (BWM) unit, an Interrupt Controller (INTC) and a Powerdown
Controller (PDC).

A new remoteproc module is added to perform the device management of
these DSP devices. The driver expects the firmware names to be of the
form "keystone-dsp<X>-fw", where X is the corresponding DSP number, and
uses the standard remoteproc core ELF loader. The support is limited
to images only using the DSP internal memories at the moment. This
remoteproc driver is also designed to work with virtio, and uses the
IPC Generation registers for performing the virtio signalling and
getting notified of exceptions.

The driver currently supports the 66AK2H/66AK2K, 66AK2L and 66AK2E
SoCs.

Say y here to support OMAP's remote processors (dual M3

Currently only supported on OMAP4.
Usually you want to say Y here, in order to enable multimedia
use-cases to run on your platform (multimedia codecs are
offloaded to remote DSP processors using this framework).
It's safe to say N here if you're not interested in multimedia
offloading or just want a bare minimum kernel.

Required for Suspend-to-RAM on AM33xx and AM43xx SoCs. Also needed
for deep CPUIdle states on AM33xx SoCs. Allows for loading of the
firmware onto these remote processors.
If unsure say N.

You want to say y here in order to enable AMP
use-cases to run on your platform (multimedia codecs are
offloaded to remote DSP processors using this framework).
This module controls the name of the firmware file that gets
loaded on the DSP. This file must reside in the /lib/firmware
directory. It can be specified via the module parameter
da8xx_fw_name=<filename>, and if not specified will default to
"rproc-dsp-fw".
It's safe to say n here if you're not interested in multimedia
