---
v3 -> v4:
* Updated Realtek copyright for 2 out of 3 files from v3
* Renamed from rtd1319-pymparticle.dts to rtd1319-pymparticles.dts
* Updated compatible from pymparticle to pym-particles
* Updated PMU compatible from armv8-pmuv3 to cortex-a55-pmu (Robin)
v2 -> v3:
* Add virtual maintenance interrupt for architecture timer
* Correct the GIC redistributor address range
v1 -> v2:
* Reserve the boot ROM address
* Reserve boot loader address
* Reserve audio/video FW address
* Reserve RPC and ring buffer address
* Reserve TEE address
* Support 1 GiB RAM by default
* Reduce rbus range to 2 MiB
* Apply the syscon for ISO,MISC,CRT,SB2,SCPU_WRAPPER
* Adjust compatible strings order in document
