If this option is enabled, U-Boot will expose the UEFI API to a loaded application, enabling it to reuse U-Boot's device drivers. if EFI_LOADER choice prompt "Store for non-volatile UEFI variables" default EFI_VARIABLE_FILE_STORE help Select where non-volatile UEFI variables shall be stored. config EFI_VARIABLE_FILE_STORE bool "Store non-volatile UEFI variables as file" depends on FAT_WRITE help Select this option if you want non-volatile UEFI variables to be stored as file /ubootefi.var on the EFI system partition. config EFI_MM_COMM_TEE bool "UEFI variables storage service via OP-TEE" depends on OPTEE help If OP-TEE is present and running StandAloneMM, dispatch all UEFI variable related operations to that. The application will verify, authenticate and store the variables on an RPMB. endchoice config EFI_VARIABLES_PRESEED bool "Initial values for UEFI variables" depends on EFI_VARIABLE_FILE_STORE help Include a file with the initial values for non-volatile UEFI variables into the U-Boot binary. If this configuration option is set, changes to authentication related variables (PK, KEK, db, dbx) are not allowed. if EFI_VARIABLES_PRESEED config EFI_VAR_SEED_FILE string "File with initial values of non-volatile UEFI variables" default ubootefi.var help File with initial values of non-volatile UEFI variables. The file must be in the same format as the storage in the EFI system partition. The easiest way to create it is by setting the non-volatile variables in U-Boot. If a relative file path is used, it is relative to the source directory. endif config EFI_GET_TIME bool "GetTime() runtime service" depends on DM_RTC default y help Provide the GetTime() runtime service at boottime. This service can be used by an EFI application to read the real time clock. config EFI_SET_TIME bool "SetTime() runtime service" depends on EFI_GET_TIME default n help Provide the SetTime() runtime service at boottime. This service can be used by an EFI application to adjust the real time clock. config EFI_DEVICE_PATH_TO_TEXT bool "Device path to text protocol" default y help The device path to text protocol converts device nodes and paths to human readable strings. config EFI_LOADER_HII bool "HII protocols" default y help The Human Interface Infrastructure is a complicated framework that allows UEFI applications to draw fancy menus and hook strings using a translation framework. U-Boot implements enough of its features to be able to run the UEFI Shell, but not more than that. config EFI_UNICODE_COLLATION_PROTOCOL2 bool "Unicode collation protocol" default y help The Unicode collation protocol is used for lexical comparisons. It is required to run the UEFI shell. if EFI_UNICODE_COLLATION_PROTOCOL2 config EFI_UNICODE_CAPITALIZATION bool "Support Unicode capitalization" default y help Select this option to enable correct handling of the capitalization of Unicode codepoints in the range 0x0000-0xffff. If this option is not set, only the the correct handling of the letters of the codepage used by the FAT file system is ensured. config EFI_UNICODE_COLLATION_PROTOCOL bool "Deprecated version of the Unicode collation protocol" default n help In EFI 1.10 a version of the Unicode collation protocol using ISO 639-2 language codes existed. This protocol is not part of the UEFI specification any longer. Unfortunately it is required to run the UEFI Self Certification Test (SCT) II, version 2.6, 2017. Choose this option for testing only. It is bound to be removed. endif config EFI_LOADER_BOUNCE_BUFFER bool "EFI Applications use bounce buffers for DMA operations" depends on ARM64 default n help Some hardware does not support DMA to full 64bit addresses. For this hardware we can create a bounce buffer so that payloads don't have to worry about platform details. config EFI_PLATFORM_LANG_CODES string "Language codes supported by firmware" default "en-US" help This value is used to initialize the PlatformLangCodes variable. Its value is a semicolon (;) separated list of language codes in native RFC 4646 format, e.g. "en-US;de-DE". The first language code is used to initialize the PlatformLang variable. config EFI_HAVE_RUNTIME_RESET # bool "Reset runtime service is available" bool default y depends on ARCH_BCM283X || FSL_LAYERSCAPE || PSCI_RESET || SYSRESET_X86 config EFI_GRUB_ARM32_WORKAROUND bool "Workaround for GRUB on 32bit ARM" default n if ARCH_QEMU default y depends on ARM && !ARM64 help GRUB prior to version 2.04 requires U-Boot to disable caches.

Once SecureBoot mode is enforced, any EFI binary can run only if it is signed with a trusted key. To do that, you need to install, at least, PK, KEK and db. endif
