2693047acd dm: core: Add a function to find any device from device tree
In some rare cases it is useful to be able to locate a device given a device
tree node offset. An example is when you have an alias that points to a node
and you want to find the associated device. The device may be SPI, MMC or
something else, but you don't need to know the uclass to find it.

Add a function to do a global search for a device, given its device tree
offset.

3039811e65 dm: core: Use debug() instead of printf() for failures
To avoid bloating SPL code, use debug() where possible in the driver model

304fbef156 dm: Move the tree/uclass dump code into its own file
In SPL it is sometimes useful to be able to obtain a dump of the current
driver model state. Since commands are not available, provide a way to
directly call the functions to output this information.

Adjust the existing commands to use these functions.

da229e4e57 sandbox: Drop special-case sandbox console code
At present printf() skips output if it can see there is no console. This
is really just an optimisation, and is not necessary. Also it is currently
incorrect in some cases. Rather than update the logic, just remove it so
that we don't need to keep it in sync.

c9689ca318 Add a way of checking the position of a structure member
U-Boot uses structures for hardware access so it is important that these
structures are correct. Add a way of asserting that a structure member is
at a particular offset. This can be created using the datasheet for the
hardware.

This implementation uses Static_assert() since BUILD_BUG_ON() only works
within functions.

4eae498e68 dm: arm: Put driver model I2C drivers before legacy ones
Driver-model I2C drivers can be picked up by the linker script rule for
legacy drivers. Change the order to avoid this.

We could make the legacy code depend on !CONFIG_DM_I2C but that is not
necessary and it is good to keep conditions to a minimum.

fa78e0a371 dm: Reduce SPL device tree size
The SPL device tree size must be minimised to save memory. Only include
properties that are needed by SPL - this is determined by the presence
of the "u-boot,dm-pre-reloc" property. Also remove a predefined list of
unused properties from the nodes that remain.

1043d0a029 fdt: Add fdtgrep tool
This tool allows us to extract subsets of a device tree file. It is used by
the SPL vuild, which needs to cut down the device tree size for use in
limited memory.

This tool was originally written for libfdt but it has not been accepted
upstream, so for now, include it in U-Boot. Several utilfdt library
functions been included inline here.

If fdtgrep is eventually accepted in libfdt then we can bring that version
of libfdt in here, and drop fdtgrep (requiring that fdtgrep is provided by
the user).

If it is not accepted then another approach would be to write a special
tool for chopping down device tree files for SPL. While it would use the
same libfdt support, it would be less code than fdtgrep.c because it would
not have general-purpose functions.

Another approach (which was used with v1 of this series) is to sprinkler all
the device tree files with #ifdef. I don't like that idea.

8f6e2e1ee1 fdt: Add a function to remove unused strings from a device tree
Property names are stored in a string table. When a node property is
removed, the string table is not updated since other nodes may have a
property with the same name.

Thus it is possible for the string table to build up a number of unused
strings. Add a function to remove these. This works by building a new device
tree from the old one, adding strings one by one as needed.
