---
 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
