The only change needed is to update get_value() to support the 'bytes'
type correctly with Python 3.
With this the dtoc unit tests pass with both Python 2 and 3:
PYTHONPATH=/tmp/b/sandbox_spl/scripts/dtc/pylibfdt python \
./tools/dtoc/dtoc -t

Since we are now using the bytes type in Python 3, the conversion in
fdt32_to_cpu() is not necessary, so drop it.
Also use 'int' instead of 'long' to convert the integer value, since
'long' is not present in Python 3.
With this, test_fdt passes with both Python 2 and 3:
PYTHONPATH=/tmp/b/sandbox_spl/scripts/dtc/pylibfdt python \
./tools/dtoc/test_fdt -t
PYTHONPATH=~/cosarm/dtc/pylibfdt:tools/patman python3 \

At present the tests run one after the other using a single CPU. This is
not very efficient. Bring in the concurrencytest module and run the tests
concurrently, using one process for each CPU by default. A -P option
allows this to be overridden, which is necessary for code-coverage to
function correctly.
This requires fixing a few tests which are currently not fully

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.

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.

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.

Sometimes it is useful to pass binman the value of an entry property from

When a test fails due to an output mismatch (e.g. due to a new property

When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from. So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry. Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.
In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.
This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents. There's also a few places where I found we did not have a tag
and have introduced one.
