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
93 Provide the SetTime() runtime service at boottime. This service
94 can be used by an EFI application to adjust the real time clock.
96 config EFI_DEVICE_PATH_TO_TEXT
97 bool "Device path to text protocol"
100 The device path to text protocol converts device nodes and paths to
101 human readable strings.
103 config EFI_LOADER_HII
107 The Human Interface Infrastructure is a complicated framework that
108 allows UEFI applications to draw fancy menus and hook strings using
109 a translation framework.
111 U-Boot implements enough of its features to be able to run the UEFI
112 Shell, but not more than that.
114 config EFI_UNICODE_COLLATION_PROTOCOL2
115 bool "Unicode collation protocol"
118 The Unicode collation protocol is used for lexical comparisons. It is
119 required to run the UEFI shell.
121 if EFI_UNICODE_COLLATION_PROTOCOL2
123 config EFI_UNICODE_CAPITALIZATION
124 bool "Support Unicode capitalization"
127 Select this option to enable correct handling of the capitalization of
128 Unicode codepoints in the range 0x0000-0xffff. If this option is not
129 set, only the the correct handling of the letters of the codepage
130 used by the FAT file system is ensured.
132 config EFI_UNICODE_COLLATION_PROTOCOL
133 bool "Deprecated version of the Unicode collation protocol"
136 In EFI 1.10 a version of the Unicode collation protocol using ISO
137 639-2 language codes existed. This protocol is not part of the UEFI
138 specification any longer. Unfortunately it is required to run the
139 UEFI Self Certification Test (SCT) II, version 2.6, 2017.
141 Choose this option for testing only. It is bound to be removed.
145 config EFI_LOADER_BOUNCE_BUFFER
146 bool "EFI Applications use bounce buffers for DMA operations"
150 Some hardware does not support DMA to full 64bit addresses. For this
151 hardware we can create a bounce buffer so that payloads don't have to
152 worry about platform details.
154 config EFI_PLATFORM_LANG_CODES
155 string "Language codes supported by firmware"
158 This value is used to initialize the PlatformLangCodes variable. Its
159 value is a semicolon (;) separated list of language codes in native
160 RFC 4646 format, e.g. "en-US;de-DE". The first language code is used
161 to initialize the PlatformLang variable.

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

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