Add trivial implementation of the clk dump in case DM is enabled.
This implementation just iterates over all the clock registered
with the CLK uclass and prints their rate.Signed-off-by: Marek Vasut

Add a board driver for the upcoming gdsys Gazerbeam board.

Since there is no canonical "board device" that can be used in board
files, it is difficult to use DM function for board initialization in
these cases.Hence, add a uclass that implements a simple "board device", which can
hold devices not suitable anywhere else in the device tree, and is also
able to read encoded information, e.g. hard-wired GPIOs on a GPIO
expander, read-only memory ICs, etc. that carry information about the
hardware.The devices of this uclass expose methods to read generic data types
(integers, strings, booleans) to encode the information provided by the
hardware.Reviewed-by: Simon Glass

Add tests for the dev_{enable,disable}_by_path functions.
Reviewed-by: Simon Glass
Signed-off-by: Mario Six -
We cannot use device structures to disable devices, since getting
them with the API functions would bind and activate the device, which
would fail if the underlying device does not exist.

Add tests for the ofnode_set_enabled, ofnode_write_string, and

Implement a set of functions to manipulate properties in a live device
tree:* ofnode_write_prop() to set generic properties of a node
* ofnode_write_string() to set string properties of a node
* ofnode_set_enabled() to either enable or disable a nodeSigned-off-by: Mario Six

When we get a problem like overlapping regions it is sometimes hard to
figure what what is going on. At present we don't write the map file in
this case. However the file does provide useful information.Catch any packing errors and write a map file (if enabled with -m) to aid
debugging.Signed-off-by: Simon Glass

For sandbox we want to put ELF files in the image since that is what we
need to execute. Add support for this.Signed-off-by: Simon Glass

Normally x86 platforms use the end-at-4gb option. This currently produces
an FMAP with positions which have a large offset. The use of end-at-4gb is
a useful convenience within binman, but we don't really want to export
a map with these offsets.Fix this by subtracting the 'skip at start' parameter.
Also put the code which convers names to fmap format, for clarity.

At present sections have no record of their parent so it is not possible
to traverse up the tree to the root and figure out the position of a
section within the image.Change the constructor to record this information.

When TPL is used on x86 we may want to program the microcode (at least for
the first CPU) early in boot. Add support for this by refactoring the
existing code to be more generic.Signed-off-by: Simon Glass
-
Sometimesi it us useful to be able to verify the content of entries with
a hash. Add an easy way to do this in binman. The hash information can be
retrieved from the device tree at run time.Signed-off-by: Simon Glass

Images and sections have the same attributes, since an image is mostly
just a top-level section. Update the docs to explain this.Signed-off-by: Simon Glass
-
It is useful to have entries which can grow automatically to fill
available space. Add support for this.Signed-off-by: Simon Glass
-
In some cases it is useful to add a group of files to the image and be
able to access them at run-time. Of course it is possible to generate
the binman config file with a set of blobs each with a filename. But for
convenience, add an entry type which can do this.Add required support (for adding nodes and string properties) into the
state module.Signed-off-by: Simon Glass
-
At present if there is only a zero-size entry in a section this is
reported as an error, e.g.:Offset 0x0 (0) is outside the section starting at 0x0 (0)
Adjust the logic in CheckEntries() to avoid this.

Add support for compressing blob entries. This can help reduce image sizes
for many types of data. It requires that the firmware be able to
decompress the data at run-time.Signed-off-by: Simon Glass

When tools are needed but not present, at present we just get an error
which can be confusing for the user. Try to be helpful by reporting the
tool as missing and suggesting a possible remedy.Also update the Run() method to support this.

Binman currently supports updating the main device tree with things like
the position of each entry. Extend this support to SPL and TPL as well,
since they may need (a subset of) this information.Also adjust DTB output files to have a .out extension since this seems
clearer than having a .dtb extension with 'out' in the name somwhere.Also add a few missing comments and update the DT setup code to use
ReadFile and WriteFile().Signed-off-by: Simon Glass

We use a fake device tree in tests most of the time since tests don't
normally care about the actual data. For example, for U-Boot proper we use
U_BOOT_DTB_DATA which is just a four-character string. This makes testing
the image output against an expected value very easy.However in some cases, such as when the test wants to check that the DT
output containing particular nodes, we do actually need the real DT. Add
support for this, along with a command-line option to select 'test mode'.Signed-off-by: Simon Glass
-
We always have a device tree for U-Boot proper. But we may also have one
for SPL and TPL. Add a new Entry method to find out what DTs an entry
has, and use that list when updating DTs.Signed-off-by: Simon Glass
-
At present we have a few calls to device-tree functions in binman and plan
to add more as we add new entry types which need to report their results.It makes sense to put this code in a central place so that we can make
sure all device trees are updated. At present we only have U-Boot proper,
but plan to add SPL and TPL too.Signed-off-by: Simon Glass

Rather than reaching into this module from control, move the code that
needs this info into state.Signed-off-by: Simon Glass
-
At present the control module has state information in it, since it is the
primary user of this. But it is a bit odd to have entries and other
modules importing control to obtain this information.It seems better to have a dedicated state module, which control can use as
well. Create a new module using code from control and update other modules
to use it.Signed-off-by: Simon Glass

Various entry implementations provide a way to obtain the default filename
for an entry. But at present there is no base-class implementation for
this function. Add one so that the API is defined.Signed-off-by: Simon Glass

This should be big endian, since that is what device tree uses. Fix it.
Signed-off-by: Simon Glass
-
At present we require the caller to manually update the device tree using
individual calls to libfdt functions. This is not ideal. It would be
better if we could make changes using the Python structure and then call a
Sync() function to write them back.Add this feature to the Fdt class. Update binman and the tests to match.

Sometimes it is useful to build only a subset of the images provided by
the binman configuration. Add a -i option for this. It can be given
multiple times to build several images. If the option is not given, all
images are built.Signed-off-by: Simon Glass
-
At present if there are two vblock entries an image their contents are
written to the same file in the output directory. This prevents checking
the contents of each separately.Fix this by adding part of the entry path to the filename, and add some
missing comments.Signed-off-by: Simon Glass

Sometimes we want to include TPL for x86 platforms, such as when we want
to select between different SPL images (e.g. for Chrome OS verified boot).
Add support for this.Signed-off-by: Simon Glass

When the value of a text entry is not provided an execption is generated
