This patchsets adds support for the aDSP, cDSP and MPSS found in the
SM8550 SoC.
The aDSP, cDSP and MPSS boot process on SM8550 now requires a secondary
"Devicetree" firmware to be passed along the main Firmware, and the cDSP
a new power domain named "NSP".
In order to satisfy the load & authentication order required by the SM8550
SoC, the following is implemented:
- "Devicetree" firmware request & load in dedicated memory
- Q6V5 prepare
- Power Domain & Clocks enable
- "Devicetree" firmware authentication
- Main firmware load in dedicated memory
- Main firmware authentication
- Q6V5 startup
- "Devicetree" firmware metadata release
- Main metadata release
When booting older platforms, the "Devicetree" steps would be
bypassed and the load & authentication order would still be valid.
