13167dac19 bootstage: Remove unused entries related to kernel/ramdisk/fdt load
Now that the code for loading these three images from a FIT is common, we
don't need individual boostage IDs for each of them.

Note: there are some minor changes in the bootstage numbering, particuarly
for kernel loading. I don't believe this matters.

a2cc9bf4c1 bootstage: Introduce sub-IDs for use with image loading
Loading a ramdisk, kernel or FDT goes through similar stages. Create
a block of IDs for each task, and define a consistent numbering within
the block. This will allow use of common code for image loading.

e9c8b44551 bootstage: Don't build for HOSTCC
We don't measure boot timing on the host, or with SPL, so use both
conditions in the bootstage header. This allows us to avoid using
conditional compilation around bootstage_...() calls. (#ifdef)

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.

e802ee0f99 bootstage: Add stubs for new bootstage functions
Some functions don't have a stub for when CONFIG_BOOTSTAGE is not defined.
Add one to avoid #ifdefs in the code when this is used in U-Boot.

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.

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.

7ac2fe2da2 OMAP: networking support for SPL
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.

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.

097e17836d bootstage: Create an initial header for boot progress integers
At present boot_stage_progress() is called with various magic numbers. The
new bootstage.h header will be used to turn these into symbolic names
throughout the code.

The intent is not that these numbers are passed to Linux. In fact by using
an enum to track them we should eventually be able to remove the explict
numbers and just have the stages count up from 0.
