This may be an opportunity to also add EDMA3- and HWA-related properties
to the platform. Then some of our resource managers (e.g. DMAN3,
EDMA3LLD, RMAN, etc) could 'auto-assign' base addrs, etc rather than
rely on the user cfg script?
I'm also wondering if, on a multi-core device, the DSP could/should be a
'peripheral' of the GPP. Codec Engine has some hard-coded uglies in our
ARM-side cfg where, given a Platform, we'd like to know more details
about the DSP (e.g. is it a C64P or C674?) - and I'm not sure there's a
reliable way to determine that across all devices(?).
