b8bcaa3ad3 Add function to print a number with grouped digits 
Move bootstage's numbering printing code into a generic place so that it can
be used by tracing also.

5d3bd34545 bootstage: Correct printf types 
The unstash code is a bit loose with its printf() types, which gives
warnings on sandbox. Correct this.

150678a582 bootstage: Copy bootstage strings post-relocation 
Any pointers to name strings that were passed to bootstage_mark_name()
pre-relocation should be copied post-relocation so that they don't get
trashed as the original location of U-Boot is re-used for other
purposes.

This change introduces a new API call that should be called from
board_init_r() after malloc has been initted on any board that uses
bootstage.

fcf509b807 bootstage: Add feature to stash/unstash bootstage info 
It is useful to be able to write the bootstage information to memory for
use by a later utility, or the Linux kernel. Provide a function to do
this as well as a function to read bootstage information back and incorporate
it into the current table.

This also makes it possible for U-Boot to chain to another U-Boot and pass
on its bootstage information.

94fd1316b7 bootstage: Store boot timings in device tree 
Add an option, CONFIG_BOOTSTAGE_FDT to pass boot timings to the kernel
in the device tree, if available. To use this, you must have
CONFIG_OF_LIBFDT defined.

0e99677358 bootstage: Add time accumulation feature 
Sometimes we want to add up the amount of time spent in a particular
activity when it is happening in a number of discrete chunks.

Add bootstage_start() to mark the start of an acitivity and
bootstage_accum() to accumulate the time since the last start. Calling
these function in pairs results in the accumulated time being collected.

094e06a523 bootstage: Export bootstage_add_record() function 
This function is not static, but not exported either. Add a prototype
in the header file and move the required enum to the header also.

3786980dd3 Move bootstage timer out of lib/time.c 
The standalone example does not have get_timer() defined, so we cannot
rely on it being available.

Move the timer function into boootstage.c to avoid this problem.

This corrects a build breakage for the standalone example on some boards.

3a608ca01d bootstage: Implement core microsecond boot time measurement 
This defines the basics of a new boot time measurement feature. This allows
logging of very accurate time measurements as the boot proceeds, by using
an available microsecond counter.

To enable the feature, define CONFIG_BOOTSTAGE in your board config file.
Also available is CONFIG_BOOTSTAGE_REPORT which will cause a report to be
printed just before handing off to the OS.

Most IDs are not named at this stage. For that I would first like to
renumber them all.
