Dave Gerlach a01bc0d5f5 remoteproc/wkup_m3: add a remoteproc driver for TI Wakeup M3
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.

Say y or m here to support STE-Modem shared memory driver.
This can be either built-in or a loadable module.
If unsure say N.

Say y here to support Wakeup M3 remote processor on TI AM33xx
and AM43xx family of SoCs.
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.

Say y here to support DA8xx/OMAP-L13x remote processors via the
remote processor framework.
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
offloading.
