AST1040 is the next-generation device following AST1030 and is primarily designed as a bridge/BIC controller platform. Introduce a dedicated AST1040 EVB machine implementation for firmware development and validation.
Although the existing ast10x0 EVB machine code already provides a reusable minibmc initialization flow, AST1040 requires different platform settings, including: - Different SYSCLK frequency - Different internal flash size To avoid overloading the existing AST1030-specific helper, introduce a separate aspeed_bic_machine_init() implementation in a dedicated source file.
