help
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.
config OMAP_REMOTEPROC_WATCHDOG
bool "OMAP remoteproc watchdog timer"
depends on OMAP_REMOTEPROC
default n
help
Say Y here to enable watchdog timer for remote processors.

for deep CPUIdle states on AM33xx SoCs. Allows for loading of the
firmware onto these remote processors.
If unsure say N.

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.
config KEYSTONE_REMOTEPROC
tristate "Keystone Remoteproc support"
depends on ARCH_KEYSTONE
help
Say Y here here to support Keystone remote processors (DSP)
via the remote processor framework.
