[v5,22/29] hw/arm/aspeed_ast27x0: Add SoC Support for AST2700 A1

Commit Message

Jamin Lin March 6, 2025, 10:38 a.m. UTC

The memory map for AST2700 A1 remains compatible with AST2700 A0. However, the
IRQ mapping has been updated for AST2700 A1, with GIC interrupts now ranging
from 192 to 201. Add a new IRQ map table for AST2700 A1.
Add "aspeed_soc_ast2700a1_class_init" to initialize the AST2700 A1 SoC.
