2 bool "Support running UEFI applications"
3 depends on (ARM || X86 || RISCV || SANDBOX) && OF_LIBFDT
4 # We need EFI_STUB_64BIT to be set on x86_64 with EFI_STUB
5 depends on !EFI_STUB || !X86_64 || EFI_STUB_64BIT
6 # We need EFI_STUB_32BIT to be set on x86_32 with EFI_STUB
7 depends on !EFI_STUB || !X86 || X86_64 || EFI_STUB_32BIT
10 select HAVE_BLOCK_DEVICE
12 imply CFB_CONSOLE_ANSI
14 Select this option if you want to run UEFI applications (like GNU
15 GRUB or iPXE) on top of U-Boot. If this option is enabled, U-Boot
16 will expose the UEFI API to a loaded application, enabling it to
17 reuse U-Boot's device drivers.
22 bool "GetTime() runtime service"
26 Provide the GetTime() runtime service at boottime. This service
27 can be used by an EFI application to read the real time clock.
30 bool "SetTime() runtime service"
31 depends on EFI_GET_TIME
34 Provide the SetTime() runtime service at boottime. This service
35 can be used by an EFI application to adjust the real time clock.
37 config EFI_DEVICE_PATH_TO_TEXT
38 bool "Device path to text protocol"
41 The device path to text protocol converts device nodes and paths to
42 human readable strings.
48 The Human Interface Infrastructure is a complicated framework that
49 allows UEFI applications to draw fancy menus and hook strings using
50 a translation framework.
52 U-Boot implements enough of its features to be able to run the UEFI
53 Shell, but not more than that.
55 config EFI_UNICODE_COLLATION_PROTOCOL2
56 bool "Unicode collation protocol"
59 The Unicode collation protocol is used for lexical comparisons. It is
60 required to run the UEFI shell.
62 if EFI_UNICODE_COLLATION_PROTOCOL2
64 config EFI_UNICODE_CAPITALIZATION
65 bool "Support Unicode capitalization"
68 Select this option to enable correct handling of the capitalization of
69 Unicode codepoints in the range 0x0000-0xffff. If this option is not
70 set, only the the correct handling of the letters of the codepage
71 used by the FAT file system is ensured.
73 config EFI_UNICODE_COLLATION_PROTOCOL
74 bool "Deprecated version of the Unicode collation protocol"
77 In EFI 1.10 a version of the Unicode collation protocol using ISO
78 639-2 language codes existed. This protocol is not part of the UEFI
79 specification any longer. Unfortunately it is required to run the
80 UEFI Self Certification Test (SCT) II, version 2.6, 2017.
82 Choose this option for testing only. It is bound to be removed.
86 config EFI_LOADER_BOUNCE_BUFFER
87 bool "EFI Applications use bounce buffers for DMA operations"
91 Some hardware does not support DMA to full 64bit addresses. For this
92 hardware we can create a bounce buffer so that payloads don't have to
93 worry about platform details.
95 config EFI_PLATFORM_LANG_CODES
96 string "Language codes supported by firmware"
99 This value is used to initialize the PlatformLangCodes variable. Its
100 value is a semicolon (;) separated list of language codes in native
101 RFC 4646 format, e.g. "en-US;de-DE". The first language code is used
102 to initialize the PlatformLang variable.
104 config EFI_HAVE_RUNTIME_RESET
105 # bool "Reset runtime service is available"
108 depends on ARCH_BCM283X || FSL_LAYERSCAPE || PSCI_RESET || SYSRESET_X86
110 config EFI_GRUB_ARM32_WORKAROUND
111 bool "Workaround for GRUB on 32bit ARM"
113 depends on ARM && !ARM64
115 GRUB prior to version 2.04 requires U-Boot to disable caches. This
116 workaround currently is also needed on systems with caches that
117 cannot be managed via CP15.
