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

55 Select this option if you want non-volatile UEFI variables to be
56 stored as file /ubootefi.var on the EFI system partition.
58 config EFI_MM_COMM_TEE
59 bool "UEFI variables storage service via OP-TEE"
62 If OP-TEE is present and running StandAloneMM, dispatch all UEFI
63 variable related operations to that. The application will verify,
64 authenticate and store the variables on an RPMB.
68 config EFI_VARIABLES_PRESEED
69 bool "Initial values for UEFI variables"
70 depends on EFI_VARIABLE_FILE_STORE
72 Include a file with the initial values for non-volatile UEFI variables

80 string "File with initial values of non-volatile UEFI variables"
83 File with initial values of non-volatile UEFI variables. The file must
84 be in the same format as the storage in the EFI system partition. The
85 easiest way to create it is by setting the non-volatile variables in
86 U-Boot. If a relative file path is used, it is relative to the source
91 config EFI_VAR_BUF_SIZE
92 int "Memory size of the UEFI variable store"
96 This defines the size in bytes of the memory area reserved for keeping
99 When using StandAloneMM (CONFIG_EFI_MM_COMM_TEE=y) this value should
100 match the value of PcdFlashNvStorageVariableSize used to compile the
103 Minimum 4096, default 16384.
106 bool "GetTime() runtime service"

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

146 without setting the EFI_OS_INDICATIONS_FILE_CAPSULE_DELIVERY_SUPPORTED
147 flag in variable OsIndications.

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

216 The device path to text protocol converts device nodes and paths to
217 human readable strings.

220 bool "Device path utilities protocol"
223 The device path utilities protocol creates and manipulates device
224 paths and device nodes. It is required to run the EFI Shell.
227 bool "Device tree fixup protocol"
228 depends on !GENERATE_ACPI_TABLE
231 The EFI device-tree fix-up protocol provides a function to let the
232 firmware apply fix-ups. This may be used by boot loaders.
234 config EFI_LOADER_HII
238 The Human Interface Infrastructure is a complicated framework that
239 allows UEFI applications to draw fancy menus and hook strings using
240 a translation framework.
242 U-Boot implements enough of its features to be able to run the UEFI
243 Shell, but not more than that.
245 config EFI_UNICODE_COLLATION_PROTOCOL2

249 The Unicode collation protocol is used for lexical comparisons. It is
250 required to run the UEFI shell.

255 bool "Support Unicode capitalization"
258 Select this option to enable correct handling of the capitalization of
259 Unicode codepoints in the range 0x0000-0xffff. If this option is not
260 set, only the the correct handling of the letters of the codepage
261 used by the FAT file system is ensured.
265 config EFI_LOADER_BOUNCE_BUFFER
266 bool "EFI Applications use bounce buffers for DMA operations"
269 Some hardware does not support DMA to full 64bit addresses. For this
270 hardware we can create a bounce buffer so that payloads don't have to
271 worry about platform details.
273 config EFI_PLATFORM_LANG_CODES
274 string "Language codes supported by firmware"
277 This value is used to initialize the PlatformLangCodes variable. Its
278 value is a semicolon (;) separated list of language codes in native
279 RFC 4646 format, e.g. "en-US;de-DE". The first language code is used
280 to initialize the PlatformLang variable.

293 depends on ARM && !ARM64
295 GRUB prior to version 2.04 requires U-Boot to disable caches. This
296 workaround currently is also needed on systems with caches that
297 cannot be managed via CP15.

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

357 Select this option to enable EFI secure boot support.
358 Once SecureBoot mode is enforced, any EFI binary can run only if
359 it is signed with a trusted key. To do that, you need to install,
360 at least, PK, KEK and db.
362 config EFI_SIGNATURE_SUPPORT
366 bool "Enable the UEFI ESRT generation"
367 depends on EFI_CAPSULE_FIRMWARE_MANAGEMENT
