Commit Message

Xianwei Zhao May 5, 2023, 7:12 a.m. UTC 
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.
