7 choices for the user to make choices with.
10 bool "Console recording"
12 This provides a way to record console output (and provide console
13 input) through circular buffers. This is mostly useful for testing.
14 Console output is recorded even when the console is silent.
15 To enable console recording, call console_record_reset_enable()
18 config CONSOLE_RECORD_INIT_F
19 bool "Enable console recording during pre-relocation init"
20 depends on CONSOLE_RECORD && SYS_MALLOC_F
23 This option enables console recording during pre-relocation init.
24 CONFIG_SYS_MALLOC_F must be enabled to use this feature.
26 config CONSOLE_RECORD_OUT_SIZE
27 hex "Output buffer size"
28 depends on CONSOLE_RECORD
29 default 0x400 if CONSOLE_RECORD
31 Set the size of the console output buffer. When this fills up, no
32 more data will be recorded until some is removed. The buffer is
33 allocated immediately after the malloc() region is ready.
35 config CONSOLE_RECORD_OUT_SIZE_F
36 hex "Output buffer size before relocation"
37 depends on CONSOLE_RECORD
38 default 0x400 if CONSOLE_RECORD
40 Set the size of the console output buffer before relocation. When
41 this fills up, no more data will be recorded until some is removed.
42 The buffer is allocated immediately after the early malloc() region is
45 config CONSOLE_RECORD_IN_SIZE
46 hex "Input buffer size"
47 depends on CONSOLE_RECORD
48 default 0x100 if CONSOLE_RECORD
50 Set the size of the console input buffer. When this contains data,
51 tstc() and getc() will use this in preference to real device input.
52 The buffer is allocated immediately after the malloc() region is
55 config DISABLE_CONSOLE
56 bool "Add functionality to disable console completely"
58 Disable console (in & out).
61 string "Board specific string to be added to uboot version string"
63 This options adds the board specific name to u-boot version.
70 All Messages with a loglevel smaller than the console loglevel will
71 be compiled in. The loglevels are defined as follows:
82 9 - debug hardware I/O
95 int "loglevel for VPL"
99 All Messages with a loglevel smaller than the console loglevel will
100 be compiled in to VPL. See LOGLEVEL for a list of available log
101 levels. Setting this to a value above 4 may increase the code size
104 config SILENT_CONSOLE
105 bool "Support a silent console"
107 This option allows the console to be silenced, meaning that no
108 output will appear on the console devices. This is controlled by
109 setting the environment variable 'silent' to a non-empty value.
110 Note this also silences the console when booting Linux.
112 When the console is set up, the variable is checked, and the
113 GD_FLG_SILENT flag is set. Changing the environment variable later
114 will update the flag.
116 config SILENT_U_BOOT_ONLY
117 bool "Only silence the U-Boot console"
118 depends on SILENT_CONSOLE
120 Normally when the U-Boot console is silenced, Linux's console is
121 also silenced (assuming the board boots into Linux). This option
122 allows the linux console to operate normally, even if U-Boot's
125 config SILENT_CONSOLE_UPDATE_ON_SET
126 bool "Changes to the 'silent' environment variable update immediately"
127 depends on SILENT_CONSOLE
128 default y if SILENT_CONSOLE
130 When the 'silent' environment variable is changed, update the
131 console silence flag immediately. This allows 'setenv' to be used
132 to silence or un-silence the console.
134 The effect is that any change to the variable will affect the
137 config SILENT_CONSOLE_UPDATE_ON_RELOC
138 bool "Allow flags to take effect on relocation"
139 depends on SILENT_CONSOLE
141 In some cases the environment is not available until relocation
142 (e.g. NAND). This option makes the value of the 'silent'
143 environment variable take effect at relocation.
145 config PRE_CONSOLE_BUFFER
146 bool "Buffer characters before the console is available"
148 Prior to the console being initialised (i.e. serial UART
149 initialised etc) all console output is silently discarded.
150 Defining CONFIG_PRE_CONSOLE_BUFFER will cause U-Boot to
151 buffer any console messages prior to the console being
152 initialised to a buffer. The buffer is a circular buffer, so
153 if it overflows, earlier output is discarded.
155 Note that this is not currently supported in SPL. It would be
156 useful to be able to share the pre-console buffer with SPL.
158 config PRE_CON_BUF_SZ
159 int "Sets the size of the pre-console buffer"
160 depends on PRE_CONSOLE_BUFFER
163 The size of the pre-console buffer affects how much console output
164 can be held before it overflows and starts discarding earlier
165 output. Normally there is very little output at this early stage,
166 unless debugging is enabled, so allow enough for ~10 lines of
169 This is a useful feature if you are using a video console and
170 want to see the full boot output on the console. Without this
171 option only the post-relocation output will be displayed.
173 config PRE_CON_BUF_ADDR
174 hex "Address of the pre-console buffer"
175 depends on PRE_CONSOLE_BUFFER
176 default 0x2f000000 if ARCH_SUNXI && MACH_SUN9I
177 default 0x4f000000 if ARCH_SUNXI && !MACH_SUN9I
178 default 0x0f000000 if ROCKCHIP_RK3288
179 default 0x0f200000 if ROCKCHIP_RK3399
181 This sets the start address of the pre-console buffer. This must
182 be in available memory and is accessed before relocation and
183 possibly before DRAM is set up. Therefore choose an address
186 We should consider removing this option and allocating the memory
187 in board_init_f_init_reserve() instead.
189 config CONSOLE_FLUSH_SUPPORT
190 bool "Enable console flush support"
193 This enables compilation of flush() function for console flush support.
196 bool "Enable console multiplexing"
197 default y if DM_VIDEO || VIDEO || LCD
199 This allows multiple devices to be used for each console 'file'.
200 For example, stdout can be set to go to serial and video.
201 Similarly, stdin can be set to come from serial and keyboard.
202 Input can be provided from either source. Console multiplexing
203 adds a small amount of size to U-Boot. Changes to the environment
204 variables stdout, stdin and stderr will take effect immediately.
206 config SYS_CONSOLE_IS_IN_ENV
207 bool "Select console devices from the environment"
208 default y if CONSOLE_MUX
210 This allows multiple input/output devices to be set at boot time.
211 For example, if stdout is set to "serial,vidconsole" then output
212 will be sent to both the serial and video devices on boot. The
213 environment variables can be updated after boot to change the
214 input/output devices.
216 config SYS_CONSOLE_OVERWRITE_ROUTINE
217 bool "Allow board control over console overwriting"
219 If this is enabled, and the board-specific function
220 overwrite_console() returns 1, the stdin, stderr and stdout are
221 switched to the serial port, else the settings in the environment
222 are used. If this is not enabled, the console will not be switched
225 config SYS_CONSOLE_ENV_OVERWRITE
226 bool "Update environment variables during console init"
228 The console environment variables (stdout, stdin, stderr) can be
229 used to determine the correct console devices on start-up. This
230 option writes the console devices to these variables on console
231 start-up (after relocation). This causes the environment to be
232 updated to match the console devices actually chosen.
234 config SYS_CONSOLE_INFO_QUIET
235 bool "Don't display the console devices on boot"
237 Normally U-Boot displays the current settings for stdout, stdin
238 and stderr on boot when the post-relocation console is set up.
239 Enable this option to suppress this output. It can be obtained by
240 calling stdio_print_current_devices() from board code.
242 config SYS_STDIO_DEREGISTER
243 bool "Allow deregistering stdio devices"
244 default y if USB_KEYBOARD
246 Generally there is no need to deregister stdio devices since they
247 are never deactivated. But if a stdio device is used which can be
248 removed (for example a USB keyboard) then this option can be
249 enabled to ensure this is handled correctly.
251 config SPL_SYS_STDIO_DEREGISTER
252 bool "Allow deregistering stdio devices in SPL"
254 Generally there is no need to deregister stdio devices since they
255 are never deactivated. But if a stdio device is used which can be
256 removed (for example a USB keyboard) then this option can be
257 enabled to ensure this is handled correctly. This is very rarely
260 config SYS_DEVICE_NULLDEV
261 bool "Enable a null device for stdio"
262 default y if SPLASH_SCREEN || SYS_STDIO_DEREGISTER
264 Enable creation of a "nulldev" stdio device. This allows silent
265 operation of the console by setting stdout to "nulldev". Enable
266 this to use a serial console under board control.
273 bool "Enable logging support"
276 This enables support for logging of status and debug messages. These
277 can be displayed on the console, recorded in a memory buffer, or
278 discarded if not needed. Logging supports various categories and
284 int "Maximum log level to record"
288 This selects the maximum log level that will be recorded. Any value
289 higher than this will be ignored. If possible log statements below
290 this level will be discarded at build time. Levels:
301 9 - debug hardware I/O
303 config LOG_DEFAULT_LEVEL
304 int "Default logging level to display"
305 default LOG_MAX_LEVEL
306 range 0 LOG_MAX_LEVEL
308 This is the default logging level set when U-Boot starts. It can
309 be adjusted later using the 'log level' command. Note that setting
310 this to a value above LOG_MAX_LEVEL will be ineffective, since the
311 higher levels are not compiled in to U-Boot.
322 9 - debug hardware I/O
325 bool "Allow log output to the console"
328 Enables a log driver which writes log records to the console.
329 Generally the console is the serial port or LCD display. Only the
330 log message is shown - other details like level, category, file and
331 line number are omitted.
334 bool "Show source file name in log messages by default"
336 Show the source file name in log messages by default. This value
337 can be overridden using the 'log format' command.
340 bool "Show source line number in log messages by default"
342 Show the source line number in log messages by default. This value
343 can be overridden using the 'log format' command.
346 bool "Show function name in log messages by default"
348 Show the function name in log messages by default. This value can
349 be overridden using the 'log format' command.
352 int "Number of characters to use for function"
355 Sets the field width to use when showing the function. Set this to
356 a larger value if you have lots of long function names, and want
360 bool "Log output to syslog server"
363 Enables a log driver which broadcasts log records via UDP port 514
367 bool "Enable logging support in SPL"
368 depends on LOG && SPL
370 This enables support for logging of status and debug messages. These
371 can be displayed on the console, recorded in a memory buffer, or
372 discarded if not needed. Logging supports various categories and
377 config SPL_LOG_MAX_LEVEL
378 int "Maximum log level to record in SPL"
383 This selects the maximum log level that will be recorded. Any value
384 higher than this will be ignored. If possible log statements below
385 this level will be discarded at build time. Levels:
396 9 - debug hardware I/O
398 config SPL_LOG_CONSOLE
399 bool "Allow log output to the console in SPL"
402 Enables a log driver which writes log records to the console.
403 Generally the console is the serial port or LCD display. Only the
404 log message is shown - other details like level, category, file and
405 line number are omitted.
410 bool "Enable logging support in TPL"
411 depends on LOG && TPL
413 This enables support for logging of status and debug messages. These
414 can be displayed on the console, recorded in a memory buffer, or
415 discarded if not needed. Logging supports various categories and
420 config TPL_LOG_MAX_LEVEL
421 int "Maximum log level to record in TPL"
426 This selects the maximum log level that will be recorded. Any value
427 higher than this will be ignored. If possible log statements below
428 this level will be discarded at build time. Levels:
439 9 - debug hardware I/O
441 config TPL_LOG_CONSOLE
442 bool "Allow log output to the console in TPL"
445 Enables a log driver which writes log records to the console.
446 Generally the console is the serial port or LCD display. Only the
447 log message is shown - other details like level, category, file and
448 line number are omitted.
453 bool "Enable logging support in VPL"
454 depends on LOG && VPL
456 This enables support for logging of status and debug messages. These
457 can be displayed on the console, recorded in a memory buffer, or
458 discarded if not needed. Logging supports various categories and
463 config VPL_LOG_MAX_LEVEL
464 int "Maximum log level to record in VPL"
467 This selects the maximum log level that will be recorded. Any value
468 higher than this will be ignored. If possible log statements below
469 this level will be discarded at build time. Levels:
480 9 - debug hardware I/O
482 config VPL_LOG_CONSOLE
483 bool "Allow log output to the console in VPL"
486 Enables a log driver which writes log records to the console.
487 Generally the console is the serial port or LCD display. Only the
488 log message is shown - other details like level, category, file and
489 line number are omitted.
493 config LOG_ERROR_RETURN
494 bool "Log all functions which return an error"
496 When an error is returned in U-Boot it is sometimes difficult to
497 figure out the root cause. For example, reading from SPI flash may
498 fail due to a problem in the SPI controller or due to the flash part
499 not returning the expected information. This option changes
500 log_ret() to log any errors it sees. With this option disabled,
503 You can add log_ret() to all functions which return an error code.
506 bool "Provide a test for logging"
510 This enables a 'log test' command to test logging. It is normally
511 executed from a pytest and simply outputs logging information
512 in various different ways to test that the logging system works
513 correctly with various settings.
522 bool "Call get_board_type() to get and display the board type"
524 If this option is enabled, checkboard() will call get_board_type()
525 to get a string containing the board type and this will be
526 displayed immediately after the model is shown on the console
529 config DISPLAY_CPUINFO
530 bool "Display information about the CPU during start up"
531 default y if ARC|| ARM || NIOS2 || X86 || XTENSA || M68K

548 Display information about the board that U-Boot is running on after
549 the relocation phase. The board function checkboard() is called to do
552 menu "Start-up hooks"
555 bool "General-purpose cyclic execution mechanism"
557 This enables a general-purpose cyclic execution infrastructure,
558 to allow "small" (run-time wise) functions to be executed at
559 a specified frequency. Things like LED blinking or watchdog
560 triggering are examples for such tasks.
564 config CYCLIC_MAX_CPU_TIME_US
565 int "Sets the max allowed time for a cyclic function in us"
568 The max allowed time for a cyclic function in us. If a functions
569 takes longer than this duration this function will get unregistered
575 bool "General-purpose event-handling mechanism"
578 This enables sending and processing of events, to allow interested
579 parties to be alerted when something happens. This is an attempt to
580 step the flow of weak functions, hooks, functions in board_f.c
581 and board_r.c and the Kconfig options below.
583 See doc/develop/event.rst for more information.
588 bool "Support event registration at runtime"
591 Enable this to support adding an event spy at runtime, without adding
592 it to the EVENT_SPy() linker list. This increases code size slightly
593 but provides more flexibility for boards and subsystems that need it.
596 bool "Enable event debugging assistance"
599 Enable this get usefui features for seeing what is happening with
600 events, such as event-type names. This adds to the code size of
601 U-Boot so can be turned off for production builds.
605 config ARCH_EARLY_INIT_R
606 bool "Call arch-specific init soon after relocation"
608 With this option U-Boot will call arch_early_init_r() soon after
609 relocation. Driver model is running by this point, and the cache
610 is on. Note that board_early_init_r() is called first, if
611 enabled. This can be used to set up architecture-specific devices.
613 config ARCH_MISC_INIT
614 bool "Call arch-specific init after relocation, when console is ready"
616 With this option U-Boot will call arch_misc_init() after
617 relocation to allow miscellaneous arch-dependent initialisation
618 to be performed. This function should be defined by the board
619 and will be called after the console is set up, after relocation.
621 config BOARD_EARLY_INIT_F
622 bool "Call board-specific init before relocation"
624 Some boards need to perform initialisation as soon as possible
625 after boot. With this option, U-Boot calls board_early_init_f()
626 after driver model is ready in the pre-relocation init sequence.
627 Note that the normal serial console is not yet set up, but the
628 debug UART will be available if enabled.
630 config BOARD_EARLY_INIT_R
631 bool "Call board-specific init after relocation"
633 Some boards need to perform initialisation as directly after
634 relocation. With this option, U-Boot calls board_early_init_r()
635 in the post-relocation init sequence.
637 config BOARD_POSTCLK_INIT
638 bool "Call board_postclk_init"
640 Some boards need this to initialize select items, after clocks /
641 timebase and before env / serial.
643 config BOARD_LATE_INIT
644 bool "Execute Board late init"
646 Sometimes board require some initialization code that might
647 require once the actual init done, example saving board specific env,
648 boot-modes etc. which eventually done at late.
650 So this config enable the late init code with the help of board_late_init
651 function which should defined on respective boards.

667 bool "Call board-specific as last setup step"
669 Some boards need to perform initialisation immediately before control
670 is passed to the command-line interpreter (e.g. for initializations
671 that depend on later phases in the init sequence). With this option,
672 U-Boot calls last_stage_init() before the command-line interpreter is

725 With this option U-Boot will call pci_init() soon after relocation,
726 which will enumerate PCI buses. This is needed, for instance, in the
727 case of DM PCI-based Ethernet devices, which will not be detected
728 without having the enumeration performed earlier.

823 which will be used to populate the /chosen/rng-seed property
824 in the device tree for the OS being booted.
826 It is up to the board code (and more generally the whole

873 allows a bootloader to try a new version of the system but roll back
874 to previous version if the new one didn't boot all the way.
881 bool "Support for a bloblist"
883 This enables support for a bloblist in U-Boot, which can be passed
884 from TPL to SPL to U-Boot proper (and potentially to Linux). The
885 blob list supports multiple binary blobs of data, each with a tag,
886 so that different U-Boot components can store data which can survive

900 depends on BLOBLIST && TPL_LIBGENERIC_SUPPORT && TPL_LIBCOMMON_SUPPORT
903 This enables a bloblist in TPL. The bloblist is set up in TPL and
904 passed to SPL and U-Boot proper.
907 bool "Support for a bloblist in VPL"
908 depends on BLOBLIST && VPL_LIBGENERIC_SUPPORT && VPL_LIBCOMMON_SUPPORT
911 This enables a bloblist in VPL. The bloblist is set up in VPL and
912 passed to SPL and U-Boot proper.

919 Select the location of the bloblist, via various means.

922 bool "Place bloblist at a fixed address in memory"
924 Select this to used a fixed memory address for the bloblist. If the
925 bloblist exists at this address from a previous phase, it used as is.
926 If not it is created at this address in U-Boot.

940 depends on BLOBLIST_FIXED
942 Sets the address of the bloblist, set up by the first part of U-Boot
943 which runs. Subsequent U-Boot phases typically use the same address.
945 This is not used if BLOBLIST_ALLOC is selected.
948 hex "Size of bloblist"
951 Sets the size of the bloblist in bytes. This must include all
952 overhead (alignment, bloblist header, record header). The bloblist
953 is set up in the first part of U-Boot to run (TPL, SPL or U-Boot
954 proper), and this sane bloblist is used for subsequent phases.

958 default BLOBLIST_SIZE if BLOBLIST_FIXED || BLOBLIST_ALLOC
959 default 0 if BLOBLIST_PASSAGE
961 Sets the size of the bloblist in bytes after relocation. Since U-Boot
962 has a lot more memory available then, it is possible to use a larger
963 size than the one set up by SPL. This bloblist is set up during the
971 prompt "Bloblist location in SPL"
973 Select the location of the bloblist, via various means. Typically
974 you should use the same value for SPL as for U-Boot, since they need
975 to look in the same place. But if BLOBLIST_ALLOC is used, then a
976 fresh bloblist will be created each time, since there is no shared
977 address (between phases) for the bloblist.
