From 6759ad39ad7d669f8fe712b6dcbb927092043497 Mon Sep 17 00:00:00 2001 From: Felix Held Date: Thu, 14 Dec 2023 20:49:59 +0100 Subject: arch/x86: introduce HAVE_CONFIGURABLE_APMC_SMI_PORT Introduce the HAVE_CONFIGURABLE_APMC_SMI_PORT Kconfig option that when not selected will result in a default implementation of pm_acpi_smi_cmd_port to be included in the build that returns APM_CNT. SoCs that provide their own pm_acpi_smi_cmd_port implementation, need to select this Kconfig option.
