Amlogic C3 is an advanced edge AI processor designed for smart IP camera
applications.
Add basic support for the C3 based Amlogic AW409 board, which describes
the following components: CPU, GIC, IRQ, Timer, UART. It's capable of
booting up into the serial console.

v2 -> V3: Remove '256m' from filename;
Keep alphabetical order of Makefile.
V1 -> V2: Remove new arch, and use ARCH_MESON;
Modify node name, and delete superfluous blank line.

What are those links ? If they are dependencies, please add them under the --- before the changelog.
