3config BOOTSTAGE
4	bool "Boot timing and reporting"
5	help
6	  Enable recording of boot time while booting. To use it, insert
7	  calls to bootstage_mark() with a suitable BOOTSTAGE_ID from
8	  bootstage.h. Only a single entry is recorded for each ID. You can
9	  give the entry a name with bootstage_mark_name(). You can also
10	  record elapsed time in a particular stage using bootstage_start()
11	  before starting and bootstage_accum() when finished. Bootstage will
12	  add up all the accumulated time and report it.
13
14	  Normally, IDs are defined in bootstage.h but a small number of
15	  additional 'user' IDs can be used by passing BOOTSTAGE_ID_ALLOC
16	  as the ID.
17
18	  Calls to show_boot_progress() will also result in log entries but
19	  these will not have names.

72config BOOTSTAGE_FDT
73	bool "Store boot timing information in the OS device tree"
74	depends on BOOTSTAGE
75	help
76	  Stash the bootstage information in the FDT. A root 'bootstage'
77	  node is created with each bootstage id as a child. Each child
78	  has a 'name' property and either 'mark' containing the
79	  mark time in microseconds, or 'accum' containing the
80	  accumulated time for that bootstage id in microseconds.
81	  For example:
82
83		bootstage {
84			154 {
85				name = "board_init_f";
86				mark = <3575678>;
87			};

99	help
100	  Some OSes do not support device tree. Bootstage can instead write
101	  the boot timing information in a binary format at a given address.
102	  This happens through a call to bootstage_stash(), typically in
103	  the CPU's cleanup_before_linux() function. You can use the
104	  'bootstage stash' and 'bootstage unstash' commands to do this on
105	  the command line.

329	  This option allows the console to be silenced, meaning that no
330	  output will appear on the console devices. This is controlled by
331	  setting the environment variable 'silent' to a non-empty value.
332	  Note this also silences the console when booting Linux.
333
334	  When the console is set up, the variable is checked, and the
335	  GD_FLG_SILENT flag is set. Changing the environment variable later
336	  will update the flag.

341	help
342	  Normally when the U-Boot console is silenced, Linux's console is

352	  When the 'silent' environment variable is changed, update the
353	  console silence flag immediately. This allows 'setenv' to be used
354	  to silence or un-silence the console.
355
356	  The effect is that any change to the variable will affect the

369	help
370	  Prior to the console being initialised (i.e. serial UART
371	  initialised etc) all console output is silently discarded.
372	  Defining CONFIG_PRE_CONSOLE_BUFFER will cause U-Boot to
373	  buffer any console messages prior to the console being
374	  initialised to a buffer. The buffer is a circular buffer, so
375	  if it overflows, earlier output is discarded.
376
377	  Note that this is not currently supported in SPL. It would be
378	  useful to be able to share the pre-console buffer with SPL.
379
380config PRE_CON_BUF_SZ
381	int "Sets the size of the pre-console buffer"
382	depends on PRE_CONSOLE_BUFFER
383	default 4096
384	help
385	  The size of the pre-console buffer affects how much console output
386	  can be held before it overflows and starts discarding earlier
387	  output. Normally there is very little output at this early stage,
388	  unless debugging is enabled, so allow enough for ~10 lines of
389	  text.
390
391	  This is a useful feature if you are using a video console and
392	  want to see the full boot output on the console. Without this
393	  option only the post-relocation output will be displayed.

400	help
401	  This sets the start address of the pre-console buffer. This must
402	  be in available memory and is accessed before relocation and
403	  possibly before DRAM is set up. Therefore choose an address
404	  carefully.

413	  This allows multiple devices to be used for each console 'file'.
414	  For example, stdout can be set to go to serial and video.
415	  Similarly, stdin can be set to come from serial and keyboard.
416	  Input can be provided from either source. Console multiplexing
417	  adds a small amount of size to U-Boot.  Changes to the environment
