From: Jamin Lin <[email protected]> AST2700 A2 is functionally identical to AST2700 A1. There are no changes to the IRQ layout, memory map, or peripheral configuration. The only difference is the silicon revision.
This commit introduces a dedicated AST2700 A2 SoC type by reusing the existing AST2700 A1 implementation and setting the A2 silicon revision accordingly.
