17 imply CFB_CONSOLE_ANSI
20 imply USB_KEYBOARD_FN_KEYS
23 Select this option if you want to run UEFI applications (like GNU
24 GRUB or iPXE) on top of U-Boot. If this option is enabled, U-Boot
25 will expose the UEFI API to a loaded application, enabling it to
26 reuse U-Boot's device drivers.
30 config EFI_SETUP_EARLY
35 prompt "Store for non-volatile UEFI variables"
36 default EFI_VARIABLE_FILE_STORE
38 Select where non-volatile UEFI variables shall be stored.
40 config EFI_VARIABLE_FILE_STORE
41 bool "Store non-volatile UEFI variables as file"
44 Select this option if you want non-volatile UEFI variables to be
45 stored as file /ubootefi.var on the EFI system partition.
47 config EFI_MM_COMM_TEE
48 bool "UEFI variables storage service via OP-TEE"
51 If OP-TEE is present and running StandAloneMM, dispatch all UEFI
52 variable related operations to that. The application will verify,
53 authenticate and store the variables on an RPMB.
57 config EFI_VARIABLES_PRESEED
58 bool "Initial values for UEFI variables"
59 depends on EFI_VARIABLE_FILE_STORE
61 Include a file with the initial values for non-volatile UEFI variables
62 into the U-Boot binary. If this configuration option is set, changes
63 to authentication related variables (PK, KEK, db, dbx) are not
66 if EFI_VARIABLES_PRESEED
68 config EFI_VAR_SEED_FILE
69 string "File with initial values of non-volatile UEFI variables"
72 File with initial values of non-volatile UEFI variables. The file must
73 be in the same format as the storage in the EFI system partition. The
74 easiest way to create it is by setting the non-volatile variables in
75 U-Boot. If a relative file path is used, it is relative to the source
81 bool "GetTime() runtime service"
85 Provide the GetTime() runtime service at boottime. This service
86 can be used by an EFI application to read the real time clock.
89 bool "SetTime() runtime service"
90 depends on EFI_GET_TIME
91 default y if ARCH_QEMU || SANDBOX
94 Provide the SetTime() runtime service at boottime. This service
95 can be used by an EFI application to adjust the real time clock.
97 config EFI_DEVICE_PATH_TO_TEXT
98 bool "Device path to text protocol"
101 The device path to text protocol converts device nodes and paths to
102 human readable strings.
104 config EFI_LOADER_HII
108 The Human Interface Infrastructure is a complicated framework that
109 allows UEFI applications to draw fancy menus and hook strings using
110 a translation framework.
112 U-Boot implements enough of its features to be able to run the UEFI
113 Shell, but not more than that.
115 config EFI_UNICODE_COLLATION_PROTOCOL2
116 bool "Unicode collation protocol"
119 The Unicode collation protocol is used for lexical comparisons. It is
120 required to run the UEFI shell.
122 if EFI_UNICODE_COLLATION_PROTOCOL2
124 config EFI_UNICODE_CAPITALIZATION
125 bool "Support Unicode capitalization"
128 Select this option to enable correct handling of the capitalization of
129 Unicode codepoints in the range 0x0000-0xffff. If this option is not
130 set, only the the correct handling of the letters of the codepage
131 used by the FAT file system is ensured.
133 config EFI_UNICODE_COLLATION_PROTOCOL
134 bool "Deprecated version of the Unicode collation protocol"
137 In EFI 1.10 a version of the Unicode collation protocol using ISO
138 639-2 language codes existed. This protocol is not part of the UEFI
139 specification any longer. Unfortunately it is required to run the
140 UEFI Self Certification Test (SCT) II, version 2.6, 2017.
142 Choose this option for testing only. It is bound to be removed.
146 config EFI_LOADER_BOUNCE_BUFFER
147 bool "EFI Applications use bounce buffers for DMA operations"
151 Some hardware does not support DMA to full 64bit addresses. For this
152 hardware we can create a bounce buffer so that payloads don't have to
153 worry about platform details.
155 config EFI_PLATFORM_LANG_CODES
156 string "Language codes supported by firmware"
159 This value is used to initialize the PlatformLangCodes variable. Its
160 value is a semicolon (;) separated list of language codes in native
161 RFC 4646 format, e.g. "en-US;de-DE". The first language code is used
162 to initialize the PlatformLang variable.

170 config EFI_GRUB_ARM32_WORKAROUND
171 bool "Workaround for GRUB on 32bit ARM"
172 default n if ARCH_QEMU
174 depends on ARM && !ARM64
176 GRUB prior to version 2.04 requires U-Boot to disable caches. This
177 workaround currently is also needed on systems with caches that
178 cannot be managed via CP15.
180 config EFI_RNG_PROTOCOL
181 bool "EFI_RNG_PROTOCOL support"
185 Provide a EFI_RNG_PROTOCOL implementation using the hardware random
186 number generator of the platform.
188 config EFI_TCG2_PROTOCOL
189 bool "EFI_TCG2_PROTOCOL support"
192 Provide a EFI_TCG2_PROTOCOL implementation using the TPM hardware
195 config EFI_LOAD_FILE2_INITRD
196 bool "EFI_FILE_LOAD2_PROTOCOL for Linux initial ramdisk"
199 Expose a EFI_FILE_LOAD2_PROTOCOL that the Linux UEFI stub can
200 use to load the initial ramdisk. Once this is enabled using
201 initrd=<ramdisk> will stop working.
203 config EFI_INITRD_FILESPEC
204 string "initramfs path"
205 default "host 0:1 initrd"
206 depends on EFI_LOAD_FILE2_INITRD
208 Full path of the initramfs file, e.g. mmc 0:2 initramfs.cpio.gz.

219 select X509_CERTIFICATE_PARSER
220 select PKCS7_MESSAGE_PARSER
224 Select this option to enable EFI secure boot support.
225 Once SecureBoot mode is enforced, any EFI binary can run only if
226 it is signed with a trusted key. To do that, you need to install,
227 at least, PK, KEK and db.
