15 select HAVE_BLOCK_DEVICE
17 imply CFB_CONSOLE_ANSI
19 Select this option if you want to run UEFI applications (like GNU
20 GRUB or iPXE) on top of U-Boot. If this option is enabled, U-Boot
21 will expose the UEFI API to a loaded application, enabling it to
22 reuse U-Boot's device drivers.
27 bool "GetTime() runtime service"
31 Provide the GetTime() runtime service at boottime. This service
32 can be used by an EFI application to read the real time clock.
35 bool "SetTime() runtime service"
36 depends on EFI_GET_TIME
39 Provide the SetTime() runtime service at boottime. This service
40 can be used by an EFI application to adjust the real time clock.
42 config EFI_DEVICE_PATH_TO_TEXT
43 bool "Device path to text protocol"
46 The device path to text protocol converts device nodes and paths to
47 human readable strings.
53 The Human Interface Infrastructure is a complicated framework that
54 allows UEFI applications to draw fancy menus and hook strings using
55 a translation framework.
57 U-Boot implements enough of its features to be able to run the UEFI
58 Shell, but not more than that.
60 config EFI_UNICODE_COLLATION_PROTOCOL2
61 bool "Unicode collation protocol"
64 The Unicode collation protocol is used for lexical comparisons. It is
65 required to run the UEFI shell.
67 if EFI_UNICODE_COLLATION_PROTOCOL2
69 config EFI_UNICODE_CAPITALIZATION
70 bool "Support Unicode capitalization"
73 Select this option to enable correct handling of the capitalization of
74 Unicode codepoints in the range 0x0000-0xffff. If this option is not
75 set, only the the correct handling of the letters of the codepage
76 used by the FAT file system is ensured.
78 config EFI_UNICODE_COLLATION_PROTOCOL
79 bool "Deprecated version of the Unicode collation protocol"
82 In EFI 1.10 a version of the Unicode collation protocol using ISO
83 639-2 language codes existed. This protocol is not part of the UEFI
84 specification any longer. Unfortunately it is required to run the
85 UEFI Self Certification Test (SCT) II, version 2.6, 2017.
87 Choose this option for testing only. It is bound to be removed.
91 config EFI_LOADER_BOUNCE_BUFFER
92 bool "EFI Applications use bounce buffers for DMA operations"
96 Some hardware does not support DMA to full 64bit addresses. For this
97 hardware we can create a bounce buffer so that payloads don't have to
98 worry about platform details.
100 config EFI_PLATFORM_LANG_CODES
101 string "Language codes supported by firmware"
104 This value is used to initialize the PlatformLangCodes variable. Its
105 value is a semicolon (;) separated list of language codes in native
106 RFC 4646 format, e.g. "en-US;de-DE". The first language code is used
107 to initialize the PlatformLang variable.
109 config EFI_HAVE_RUNTIME_RESET
110 # bool "Reset runtime service is available"
113 depends on ARCH_BCM283X || FSL_LAYERSCAPE || PSCI_RESET || SYSRESET_X86
115 config EFI_GRUB_ARM32_WORKAROUND
116 bool "Workaround for GRUB on 32bit ARM"
118 depends on ARM && !ARM64
120 GRUB prior to version 2.04 requires U-Boot to disable caches. This
121 workaround currently is also needed on systems with caches that
122 cannot be managed via CP15.
