libfdt: Update to latest pylibfdt implementation

2018-08-08T11:49:36+00:00

The enhanced pylibfdt support in U-Boot needed for binman was a
placeholder while upstreaming of this work continued. This is now
complete, so bring in the changes and update the tools as needed.

There are quite a few changes since we decided to split the
implementation into three fdt classes instead of two.

The Fdt.del_node() method was unfortunately missed in this process and
will be dealt with later. It exists in U-Boot but not upstream.

Further syncing of libfdt probably needs to wait until we assess the
code-size impact of all the new checking code on SPL and possibly provide
a way to disable it.

dtoc: Add a function to obtain a list of phandles

2018-08-01T22:30:48+00:00

Add a function which can decode a property containing a list of phandles.
This is useful for finding nodes linked to a property. Also provide a way
to look up a single phandle and get the Fdt object from a Node.

dtoc: Export the _FindNode() function

2018-08-01T22:30:48+00:00

This is useful for clients that want to find a node. Export it so it can
be used by others.

binman: Add an entry filled with a repeating byte

2018-08-01T22:30:48+00:00

It is sometimes useful to have an area of the image which is all zeroes,
or all 0xff. This can often be achieved by padding the size of an an
existing entry and setting the pad byte for an entry or image.

But it is useful to have an explicit means of adding blocks of repeating
data to the image. Add a 'fill' entry type to handle this.

binman: Add support for passing arguments to entries

2018-08-01T22:30:47+00:00

Sometimes it is useful to pass binman the value of an entry property from
the command line. For example some entries need access to files and it is
not always convenient to put these filenames in the image definition
(device tree).

Add a -a option which can be used like this:

   -a=

where

    is the property to set
    is the value to set it to

dtoc: Avoid unwanted output during tests

2018-07-09T15:11:00+00:00

At present some warnings are printed to indicate failures which are a
known part of running the tests. Suppress these.

dtoc: Increase code coverage to 100%

2018-07-09T15:11:00+00:00

Add more tests to increase dtoc code coverage to 100%.

Correct a whitespace error in some test .dts files at the same time.

dtoc: Add a test for code coverage

2018-07-09T15:11:00+00:00

Add a -T option to run a code-coverage test on dtoc. At present this is
about 96%. Future work will increase it to 100%.
