+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
+			  0          0  reset
+		  3,575,678  3,575,678  board_init_f start

+config BOOTSTAGE_RECORD_COUNT
+	int "Number of boot stage records to store"
+	default 30

+	  This is the size of the bootstage record list and is the maximum
+	  number of bootstage records that can be recorded.
+
+config SPL_BOOTSTAGE_RECORD_COUNT

+	default 5
+	help
+	  This is the size of the bootstage record list and is the maximum
+	  number of bootstage records that can be recorded.
+
+config TPL_BOOTSTAGE_RECORD_COUNT
+	int "Number of boot stage records to store for TPL"
+	default 5
+	help
+	  This is the size of the bootstage record list and is the maximum
+	  number of bootstage records that can be recorded.
+
+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
+	hex "Size of boot timing stash region"
+	default 0x1000
+	help
+	  This should be large enough to hold the bootstage stash. A value of
+	  4096 (4KiB) is normally plenty.
+
+config SHOW_BOOT_PROGRESS
+	bool "Show boot progress in a board-specific manner"
+	help
+	  Defining this option allows to add some board-specific code (calling
+	  a user-provided function show_boot_progress(int) that enables you to
+	  show the system's boot progress on some display (for example, some
+	  LEDs) on your board. At the moment, the following checkpoints are
+	  implemented:
