25 Select this option if you want to run UEFI applications (like GNU
26 GRUB or iPXE) on top of U-Boot. If this option is enabled, U-Boot
27 will expose the UEFI API to a loaded application, enabling it to
28 reuse U-Boot's device drivers.
32 config CMD_BOOTEFI_BOOTMGR
33 bool "UEFI Boot Manager"
36 Select this option if you want to select the UEFI binary to be booted
37 via UEFI variables Boot####, BootOrder, and BootNext. This enables the
38 'bootefi bootmgr' command.

54 stored as file /ubootefi.var on the EFI system partition.
56 config EFI_MM_COMM_TEE
57 bool "UEFI variables storage service via OP-TEE"
60 If OP-TEE is present and running StandAloneMM, dispatch all UEFI
61 variable related operations to that. The application will verify,
62 authenticate and store the variables on an RPMB.

68 depends on EFI_VARIABLE_FILE_STORE

81 File with initial values of non-volatile UEFI variables. The file must
82 be in the same format as the storage in the EFI system partition. The
83 easiest way to create it is by setting the non-volatile variables in
84 U-Boot. If a relative file path is used, it is relative to the source
89 config EFI_VAR_BUF_SIZE
90 int "Memory size of the UEFI variable store"
94 This defines the size in bytes of the memory area reserved for keeping
97 When using StandAloneMM (CONFIG_EFI_MM_COMM_TEE=y) this value should
98 match the value of PcdFlashNvStorageVariableSize used to compile the
101 Minimum 4096, default 16384.

130 bool "Enable capsule-on-disk support"
131 select EFI_HAVE_CAPSULE_SUPPORT
133 Select this option if you want to use capsule-on-disk feature,
134 that is, capsules can be fetched and executed from files
135 under a specific directory on UEFI system partition instead of
136 via UpdateCapsule API.
138 config EFI_IGNORE_OSINDICATIONS
139 bool "Ignore OsIndications for CapsuleUpdate on-disk"
140 depends on EFI_CAPSULE_ON_DISK
142 There are boards where U-Boot does not support SetVariable at runtime.

152 Normally, without this option enabled, capsules will be
153 executed only at the first time of invoking one of efi command.
154 If this option is enabled, capsules will be enforced to be
155 executed as part of U-Boot initialisation so that they will
156 surely take place whatever is set to distro_bootcmd.

221 The device path utilities protocol creates and manipulates device
222 paths and device nodes. It is required to run the EFI Shell.
225 bool "Device tree fixup protocol"
226 depends on !GENERATE_ACPI_TABLE
229 The EFI device-tree fix-up protocol provides a function to let the
230 firmware apply fix-ups. This may be used by boot loaders.
232 config EFI_LOADER_HII
236 The Human Interface Infrastructure is a complicated framework that
237 allows UEFI applications to draw fancy menus and hook strings using
238 a translation framework.
240 U-Boot implements enough of its features to be able to run the UEFI
241 Shell, but not more than that.

256 Select this option to enable correct handling of the capitalization of
257 Unicode codepoints in the range 0x0000-0xffff. If this option is not
258 set, only the the correct handling of the letters of the codepage
259 used by the FAT file system is ensured.
263 config EFI_LOADER_BOUNCE_BUFFER
264 bool "EFI Applications use bounce buffers for DMA operations"
267 Some hardware does not support DMA to full 64bit addresses. For this
268 hardware we can create a bounce buffer so that payloads don't have to
269 worry about platform details.
271 config EFI_PLATFORM_LANG_CODES

275 This value is used to initialize the PlatformLangCodes variable. Its
276 value is a semicolon (;) separated list of language codes in native

278 to initialize the PlatformLang variable.

295 cannot be managed via CP15.

325 and one for the configuration table that is required from the spec
327 config EFI_LOAD_FILE2_INITRD
328 bool "EFI_FILE_LOAD2_PROTOCOL for Linux initial ramdisk"
331 Linux v5.7 and later can make use of this option. If the boot option
332 selected by the UEFI boot manager specifies an existing file to be used
333 as initial RAM disk, a Linux specific Load File2 protocol will be
334 installed and Linux 5.7+ will ignore any initrd=<ramdisk> command line

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