Huang Yiwei 7e16ba331e firmware: SDEI: Allow sdei initialization without ACPI_APEI_GHES ... [ Upstream commit 59529bbe64 ] SDEI usually initialize with the ACPI table, but on platforms where ACPI is not used, the SDEI feature can still be used to handle specific firmware calls or other customized purposes. Therefore, it is not necessary for ARM_SDE_INTERFACE to depend on ACPI_APEI_GHES. In commit dc4e8c07e9 ("ACPI: APEI: explicit init of HEST and GHES in acpi_init()"), to make APEI ready earlier, sdei_init was moved into acpi_ghes_init instead of being a standalone initcall, adding ACPI_APEI_GHES dependency to ARM_SDE_INTERFACE. This restricts the flexibility and usability of SDEI. This patch corrects the dependency in Kconfig and splits sdei_init() into two separate functions: sdei_init() and acpi_sdei_init(). sdei_init() will be called by arch_initcall and will only initialize the platform driver, while acpi_sdei_init() will initialize the device from acpi_ghes_init() when ACPI is ready. This allows the initialization of SDEI without ACPI_APEI_GHES enabled.
