bootstage: Add feature to stash/unstash bootstage info

2012-10-02T22:52:40+00:00

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.

bootstage: Store boot timings in device tree

2012-10-02T20:39:33+00:00

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.

bootstage: Add time accumulation feature

2012-10-02T20:39:33+00:00

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.

bootstage: Export bootstage_add_record() function

2012-10-02T20:39:33+00:00

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.

OMAP: networking support for SPL

2012-10-01T17:02:14+00:00

This patch adds support for networking in SPL. Some devices are
capable of loading SPL via network so it makes sense to load the
main U-Boot binary via network too. This patch tries to use
existing network code as much as possible. Unfortunately, it depends
on environment which in turn depends on other code so SPL size
is increased significantly. No effort was done to decouple network
code and environment so far.

Move bootstage timer out of lib/time.c

2012-04-10T21:35:32+00:00

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.

bootstage: Implement core microsecond boot time measurement

2012-03-18T20:42:14+00:00

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.

Timer summary in microseconds:
       Mark    Elapsed  Stage
          0          0  reset
    205,000    205,000  board_init_f

bootstage: Replace show_boot_progress/error() with bootstage_...()

2012-03-18T20:41:39+00:00

These calls should not be made directly any more, since bootstage
will call the show_boot_...() functions as needed.
