Subject: [PATCH v3 0/3] remoteproc: qcom: Introduce DSP support for SM8650

Add the bindings and driver changes for DSP support on the
SM8650 platform in order to enable the aDSP, cDSP and MPSS
subsystems to boot.

Compared to SM8550, where SM8650 uses the same dual firmware files,
(dtb file and main firmware) the memory zones requirement has changed:
- cDSP: now requires 2 memory zones to be configured as shared
  between the cDSP and the HLOS subsystem
- MPSS: In addition to the memory zone required for the SM8550
  MPSS, another one is required to be configured for MPSS
  usage only.

In order to handle this and avoid code duplication, the region_assign_*
code patch has been made more generic and is able handle multiple
DSP-only memory zones (for MPSS) or DSP-HLOS shared memory zones (cDSP)
in the same region_assign functions.

Dependencies: None

For convenience, a regularly refreshed linux-next based git tree containing
all the SM8650 related work is available at:
