config BOOTSTAGE
	bool "Boot timing and reporting"
	help
	  Enable recording of boot time while booting. To use it, insert
	  calls to bootstage_mark() with a suitable BOOTSTAGE_ID from
	  bootstage.h. Only a single entry is recorded for each ID. You can
	  give the entry a name with bootstage_mark_name(). You can also
	  record elapsed time in a particular stage using bootstage_start()
	  before starting and bootstage_accum() when finished. Bootstage will
	  add up all the accumulated time and report it.

	  Normally, IDs are defined in bootstage.h but a small number of
	  additional 'user' IDs can be used by passing BOOTSTAGE_ID_ALLOC
	  as the ID.

	  Calls to show_boot_progress() will also result in log entries but
	  these will not have names.

config SPL_BOOTSTAGE
	bool "Boot timing and reported in SPL"
	depends on BOOTSTAGE
	help
	  Enable recording of boot time in SPL. To make this visible to U-Boot
	  proper, enable BOOTSTAGE_STASH as well. This will stash the timing
	  information when SPL finishes and load it when U-Boot proper starts
	  up.

config TPL_BOOTSTAGE
	bool "Boot timing and reported in TPL"
	depends on BOOTSTAGE
	help
	  Enable recording of boot time in SPL. To make this visible to U-Boot
	  proper, enable BOOTSTAGE_STASH as well. This will stash the timing
	  information when TPL finishes and load it when U-Boot proper starts
	  up.

config BOOTSTAGE_REPORT
	bool "Display a detailed boot timing report before booting the OS"
	depends on BOOTSTAGE
	help
	  Enable output of a boot time report just before the OS is booted.
	  This shows how long it took U-Boot to go through each stage of the
	  boot process. The report looks something like this:

		Timer summary in microseconds:
		       Mark    Elapsed  Stage

config BOOTSTAGE_FDT
	bool "Store boot timing information in the OS device tree"
	depends on BOOTSTAGE
	help
	  Stash the bootstage information in the FDT. A root 'bootstage'
	  node is created with each bootstage id as a child. Each child
	  has a 'name' property and either 'mark' containing the
	  mark time in microseconds, or 'accum' containing the
	  accumulated time for that bootstage id in microseconds.
	  For example:

		bootstage {
			154 {
				name = "board_init_f";
				mark = <3575678>;
			};
			170 {
				name = "lcd";
				accum = <33482>;

	  Code in the Linux kernel can find this in /proc/devicetree.

config BOOTSTAGE_STASH
	bool "Stash the boot timing information in memory before booting OS"
	depends on BOOTSTAGE
	help
	  Some OSes do not support device tree. Bootstage can instead write
	  the boot timing information in a binary format at a given address.
	  This happens through a call to bootstage_stash(), typically in
	  the CPU's cleanup_before_linux() function. You can use the
	  'bootstage stash' and 'bootstage unstash' commands to do this on
	  the command line.

config BOOTSTAGE_STASH_ADDR
	hex "Address to stash boot timing information"
	default 0
	help
	  Provide an address which will not be overwritten by the OS when it
	  starts, so that it can read this information when ready.

config BOOTSTAGE_STASH_SIZE

	help
	  This option allows the console to be silenced, meaning that no

	  setting the environment variable 'silent' to a non-empty value.
	  Note this also silences the console when booting Linux.

	  When the console is set up, the variable is checked, and the
	  GD_FLG_SILENT flag is set. Changing the environment variable later
	  will update the flag.

config SILENT_U_BOOT_ONLY

	depends on SILENT_CONSOLE
	help
	  Normally when the U-Boot console is silenced, Linux's console is

config PRE_CONSOLE_BUFFER

	help
	  Prior to the console being initialised (i.e. serial UART
	  initialised etc) all console output is silently discarded.
	  Defining CONFIG_PRE_CONSOLE_BUFFER will cause U-Boot to
	  buffer any console messages prior to the console being
	  initialised to a buffer. The buffer is a circular buffer, so
	  if it overflows, earlier output is discarded.

	  Note that this is not currently supported in SPL. It would be
	  useful to be able to share the pre-console buffer with SPL.

config PRE_CON_BUF_SZ
	int "Sets the size of the pre-console buffer"
	depends on PRE_CONSOLE_BUFFER
	default 4096
	help
	  The size of the pre-console buffer affects how much console output
	  can be held before it overflows and starts discarding earlier
	  output. Normally there is very little output at this early stage,
	  unless debugging is enabled, so allow enough for ~10 lines of
	  text.

	  This is a useful feature if you are using a video console and
	  want to see the full boot output on the console. Without this
	  option only the post-relocation output will be displayed.

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

	  We should consider removing this option and allocating the memory
	  in board_init_f_init_reserve() instead.

config CONSOLE_MUX
	bool "Enable console multiplexing"
	default y if DM_VIDEO || VIDEO || LCD
	help
	  This allows multiple devices to be used for each console 'file'.
	  For example, stdout can be set to go to serial and video.
	  Similarly, stdin can be set to come from serial and keyboard.
	  Input can be provided from either source. Console multiplexing
	  adds a small amount of size to U-Boot.  Changes to the environment
	  variables stdout, stdin and stderr will take effect immediately.

config SYS_CONSOLE_IS_IN_ENV
	bool "Select console devices from the environment"
	default y if CONSOLE_MUX

config SYS_CONSOLE_ENV_OVERWRITE
	bool "Update environment variables during console init"
	help
	  The console environment variables (stdout, stdin, stderr) can be
	  used to determine the correct console devices on start-up. This
	  option writes the console devices to these variables on console
	  start-up (after relocation). This causes the environment to be
	  updated to match the console devices actually chosen.

config SYS_CONSOLE_INFO_QUIET

	help
	  With this option U-Boot will call arch_misc_init() after
	  relocation to allow miscellaneous arch-dependent initialisation
	  to be performed. This function should be defined by the board
	  and will be called after the console is set up, after relocation.

config BOARD_EARLY_INIT_F
	bool "Call board-specific init before relocation"
	help
	  Some boards need to perform initialisation as soon as possible
	  after boot. With this option, U-Boot calls board_early_init_f()
	  after driver model is ready in the pre-relocation init sequence.
	  Note that the normal serial console is not yet set up, but the
	  debug UART will be available if enabled.

config BOARD_EARLY_INIT_R
	bool "Call board-specific init after relocation"
	help
	  Some boards need to perform initialisation as directly after
	  relocation. With this option, U-Boot calls board_early_init_r()
	  in the post-relocation init sequence.

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