This introduces initial support for the Aspeed AST27xx SoC and the AST2700
Evaluation Board (EVB) to the Linux kernel. The AST27xx is the 8th
generation Baseboard Management Controller (BMC) SoC from Aspeed,
featuring improved performance, enhanced security, and expanded I/O
capabilities compared to previous generations.
