We can only use CMA on systems that have an MMU, because of the requirement to use memory migration. NOMMU systems are rather constrained to start with, but it seems reasonable to assume that DMA allocations can still succeed in the constrained case for remoteproc on NOMMU, so this patch changes the da8xx implementation to not rely on CMA when the MMU is disabled.

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.

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.
