Add a remoteproc driver to load the firmware and boot a small Wakeup M3 processor present on TI AM33xx and AM43xx SoCs. This Wakeup M3 remote processor is an integrated Cortex M3 that allows the SoC to enter the lowest possible power state by taking control from the MPU after it has gone into its own low power state and shutting off any additional peripherals. The Wakeup M3 processor has two internal memory regions - 16 kB of unified instruction memory called UMEM used to store executable code, and 8 kB of data memory called DMEM used for all data sections. The Wakeup M3 processor executes its code entirely from within the UMEM and uses the DMEM for any data. It does not use any external memory or any other external resources. The device address view has the UMEM at address 0x0 and DMEM at address 0x80000, and these are computed automatically within the driver based on relative address calculation from the corresponding device tree IOMEM resources. These device addresses are used to aid the core remoteproc ELF loader code to properly translate and load the firmware segments through the .rproc_da_to_va ops.

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

and DSP on OMAP4) via the remote processor framework.
|
|
|

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.

This can be either built-in or a loadable module.

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".
