15 select HAVE_BLOCK_DEVICE
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.
31 bool "GetTime() runtime service"
35 Provide the GetTime() runtime service at boottime. This service
36 can be used by an EFI application to read the real time clock.
39 bool "SetTime() runtime service"
40 depends on EFI_GET_TIME
43 Provide the SetTime() runtime service at boottime. This service
44 can be used by an EFI application to adjust the real time clock.
46 config EFI_DEVICE_PATH_TO_TEXT
47 bool "Device path to text protocol"
50 The device path to text protocol converts device nodes and paths to
51 human readable strings.
57 The Human Interface Infrastructure is a complicated framework that
58 allows UEFI applications to draw fancy menus and hook strings using
59 a translation framework.
61 U-Boot implements enough of its features to be able to run the UEFI
62 Shell, but not more than that.
64 config EFI_UNICODE_COLLATION_PROTOCOL2
65 bool "Unicode collation protocol"
68 The Unicode collation protocol is used for lexical comparisons. It is
69 required to run the UEFI shell.
71 if EFI_UNICODE_COLLATION_PROTOCOL2
73 config EFI_UNICODE_CAPITALIZATION
74 bool "Support Unicode capitalization"
77 Select this option to enable correct handling of the capitalization of
78 Unicode codepoints in the range 0x0000-0xffff. If this option is not
79 set, only the the correct handling of the letters of the codepage
80 used by the FAT file system is ensured.
82 config EFI_UNICODE_COLLATION_PROTOCOL
83 bool "Deprecated version of the Unicode collation protocol"
86 In EFI 1.10 a version of the Unicode collation protocol using ISO
87 639-2 language codes existed. This protocol is not part of the UEFI
88 specification any longer. Unfortunately it is required to run the
89 UEFI Self Certification Test (SCT) II, version 2.6, 2017.
91 Choose this option for testing only. It is bound to be removed.
95 config EFI_LOADER_BOUNCE_BUFFER
96 bool "EFI Applications use bounce buffers for DMA operations"
100 Some hardware does not support DMA to full 64bit addresses. For this
101 hardware we can create a bounce buffer so that payloads don't have to
102 worry about platform details.
104 config EFI_PLATFORM_LANG_CODES
105 string "Language codes supported by firmware"
108 This value is used to initialize the PlatformLangCodes variable. Its
109 value is a semicolon (;) separated list of language codes in native
110 RFC 4646 format, e.g. "en-US;de-DE". The first language code is used
111 to initialize the PlatformLang variable.
113 config EFI_HAVE_RUNTIME_RESET

117 depends on ARCH_BCM283X || FSL_LAYERSCAPE || PSCI_RESET || SYSRESET_X86
119 config EFI_GRUB_ARM32_WORKAROUND
120 bool "Workaround for GRUB on 32bit ARM"
122 depends on ARM && !ARM64
124 GRUB prior to version 2.04 requires U-Boot to disable caches. This
125 workaround currently is also needed on systems with caches that
126 cannot be managed via CP15.
128 config EFI_RNG_PROTOCOL
129 bool "EFI_RNG_PROTOCOL support"
133 Provide a EFI_RNG_PROTOCOL implementation using the hardware random
134 number generator of the platform.
136 config EFI_LOAD_FILE2_INITRD
137 bool "EFI_FILE_LOAD2_PROTOCOL for Linux initial ramdisk"
140 Expose a EFI_FILE_LOAD2_PROTOCOL that the Linux UEFI stub can
141 use to load the initial ramdisk. Once this is enabled using
142 initrd=<ramdisk> will stop working.
144 config EFI_INITRD_FILESPEC
145 string "initramfs path"
146 default "host 0:1 initrd"
147 depends on EFI_LOAD_FILE2_INITRD
149 Full path of the initramfs file, e.g. mmc 0:2 initramfs.cpio.gz.

152 bool "Enable EFI secure boot support"
153 depends on EFI_LOADER

159 select ASYMMETRIC_PUBLIC_KEY_SUBTYPE
160 select X509_CERTIFICATE_PARSER
161 select PKCS7_MESSAGE_PARSER
164 Select this option to enable EFI secure boot support.
165 Once SecureBoot mode is enforced, any EFI binary can run only if
166 it is signed with a trusted key. To do that, you need to install,
167 at least, PK, KEK and db.
169 config EFI_MM_COMM_TEE
170 bool "UEFI variables storage service via OP-TEE"
174 If OP-TEE is present and running StandAloneMM, dispatch all UEFI variable
175 related operations to that. The application will verify, authenticate and
176 store the variables on an RPMB.
