725700dcbf ARM: OMAP4/5: Centralize gpi2c_init
Centralize gpi2c_init into omap_common from the sys_proto header so

93e6253d11 ARM: OMAP4/5: Centralize early clock initialization
Early clock initialization is currently done in two stages for OMAP4/5
SoCs. The first stage is the initialization of console clocks and
then we initialize basic clocks for functionality necessary for SoC
initialization and basic board functionality.

By splitting up prcm_init and centralizing this clock initialization,
we setup the code for follow on patches that can do board specific
initialization such as board detection which will depend on these
basic clocks.

As part of this change, since the early clock initialization
is centralized, we no longer need to expose the console clock
initialization.

NOTE: we change the sequence slightly by initializing console clocks
timer after the io settings are complete, but this is not expected
to have any functioanlity impact since we setup the basic IO drive
strength initialization as part of do_io_settings.

cdf172461c spl: Add a way to specify a list of device trees to include
When building a FIT, more than one device tree can be included. The board
can select (at run-time) the one that it wants.

Add a Kconfig option to allow the list of devices trees (supported by the
board) to be specified.

When using SPL_LOAD_FIT, build u-boot.img in FIT format instead of the
legacy image format. Include all the listed device tree files in this FIT.

722ebc8f84 mkimage: Support placing data outside the FIT
One limitation of FIT is that all the data is 'inline' within it, using a
'data' property in each image node. This means that to find out what is in
the FIT it is necessary to scan the entire file. Once loaded it can be
scanned and then the images can be copied to the correct place in memory.

In SPL it can take a significant amount of time to copy images around in
memory. Also loading data that does not end up being used is wasteful. It
would be useful if the FIT were small, acting as a directory, with the
actual data stored elsewhere.

This allows SPL to load the entire FIT, without the images, then load the
images it wants later.

Add a -E option to mkimage to request that it output an 'external' FIT.

fb4cce0f98 mkimage: Support adding device tree files to a FIT
To make the auto-FIT feature useful we need to be able to provide a list of

support for this feature.

So far there is no support for hashing or verified boot using this method.

8e35bb07eb mkimage: Support automatic creating of a FIT without a .its
At present, when generating a FIT, mkimage requires a .its file containing
the structure of the FIT and referring to the images to be included.

Creating the .its file is a separate step that makes it harder to use FIT.
This is not required for creating legacy images.

Often the FIT is pretty standard, consisting of an OS image, some device
tree files and a single configuration. We can handle this case automatically
and avoid needing a .its file at all.

To start with, support automatically generate the FIT using a new '-f auto'
option. Initially this only supports adding a single image (e.g. a linux
kernel) and a single configuration.

73223f0e1b Kconfig: Move CONFIG_FIT and related options to Kconfig
There are already two FIT options in Kconfig but the CONFIG options are
still in the header files. We need to do a proper move to fix this.

Move these options to Kconfig and tidy up board configuration:

   CONFIG_FIT
   CONFIG_OF_BOARD_SETUP
   CONFIG_OF_SYSTEM_SETUP
   CONFIG_FIT_SIGNATURE
   CONFIG_FIT_BEST_MATCH
   CONFIG_FIT_VERBOSE
   CONFIG_OF_STDOUT_VIA_ALIAS
   CONFIG_RSA

Unfortunately the first one is a little complicated. We need to make sure
this option is not enabled in SPL by this change. Also this option is
enabled automatically in the host builds by defining CONFIG_FIT in the
image.h file. To solve this, add a new IMAGE_USE_FIT #define which can
be used in files that are built on the host but must also build for U-Boot
and SPL.

For now, make sure that USB is reset after each test, so that the counters

Note: this is not a perfect solution: It a USB test fails it will exit
immediately and leave USB un-reset. The impact here is that it may cause
subsequence test failures in the same run.

96e5b03c8a dm: part: Convert partition API use to linker lists
We can use linker lists instead of explicitly declaring each function.
This makes the code shorter by avoiding switch() statements and lots of
header file declarations.

While this does clean up the code it introduces a few code issues with SPL.
SPL never needs to print partition information since this all happens from
commands. SPL mostly doesn't need to obtain information about a partition
either, except in a few cases. Add these cases so that the code will be
dropped from each partition driver when not needed. This avoids code bloat.

I think this is still a win, since it is not a bad thing to be explicit
about which features are used in SPL. But others may like to weigh in.
