- Add ast2700-evb.dts for the ASPEED AST2700 Evaluation Board.
- Set board model and compatible strings: "aspeed,ast2700-evb",
"aspeed,ast2700".
- Reference the common AST2700 SoC device tree aspeed-g7.dtsi.
- Define memory layout and reserved-memory regions for
MCU firmware, ATF, and OP-TEE.
- Add OP-TEE firmware node with SMC method.
- Set up serial12 as the default console.
