help
Select this option if you want to run UEFI applications (like GNU
GRUB or iPXE) on top of U-Boot. 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.

help
Select where non-volatile UEFI variables shall be stored.
config EFI_VARIABLE_FILE_STORE
bool "Store non-volatile UEFI variables as file"

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.

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

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.

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.

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"

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.

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.

bool "Workaround for GRUB on 32bit ARM"
default y
depends on ARM && !ARM64
help
GRUB prior to version 2.04 requires U-Boot to disable caches. This
workaround currently is also needed on systems with caches that
cannot be managed via CP15.
config EFI_RNG_PROTOCOL

help
Provide a EFI_RNG_PROTOCOL implementation using the hardware random
number generator of the platform.
config EFI_LOAD_FILE2_INITRD

help
Expose a EFI_FILE_LOAD2_PROTOCOL that the Linux UEFI stub can
use to load the initial ramdisk. Once this is enabled using
initrd=<ramdisk> will stop working.

Select this option to enable EFI secure boot support.
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.
