It enables a serial console on UART0 and the volume down key on the SoC keypad. The power and volume up keys are connected to the MT6363 PMIC, which isn't supported yet. The DT only describes the memory that Linux itself uses, which is the ramoops region. The bootloader updates the /memory node and adds the firmware carveouts to /reserved-memory, so their addresses are not hardcoded here. This DT must not be booted with a bootloader that does not do this, as Linux would then use memory owned by the firmware. The ramoops zone sizes place the console zone at the offset where the bootloader expects to find it.
