This is to allow secureboot of accelerated machines to boot as quickly as possible when verifying each module signature. For example: given CONFIG_MODULE_SIG_SHA512=y All of CONFIG_CRYPTO_SHA512 policy<{'amd64': 'y', 'arm64': 'y', 'armhf': 'y', 'ppc64el': 'y', 'riscv64': 'y', 's390x': 'y'}> CONFIG_CRYPTO_SHA512 note<'module signing'> CONFIG_CRYPTO_SHA512_ARM policy<{'armhf': 'm'}> CONFIG_CRYPTO_SHA512_ARM64 policy<{'arm64': 'm'}> CONFIG_CRYPTO_SHA512_ARM64_CE policy<{'arm64': 'm'}> CONFIG_CRYPTO_SHA512_S390 policy<{'s390x': 'm'}> CONFIG_CRYPTO_SHA512_SSSE3 policy<{'amd64': 'm'}> Should be =y on secureboot platforms.
