However, this test file only supports for ARM32. To support all ASPEED SOCs such as AST2700 whose CPU architecture is aarch64, introduces a new aspeed-smc-utils source file and move all common APIs and testcases from aspeed_smc-test.c to aspeed-smc-utils.c. Finally, users are able to re-used these testcase for AST2700 and future ASPEED SOCs testing.
