binman: Run tests concurrently

2018-10-08T13:34:34Z

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 independent. At some point we might consider doing this across all pytests in U-Boot. There is a pytest version that supports specifying the number of processes to use, but it did not work for me.

binman: Fix up removal of temporary directories

2018-10-08T13:34:34Z

At present 'make check' leaves some temporary directories around. Part of this is because we call tools.PrepareOutputDir() twice in some cases, without calling tools.FinaliseOutputDir() in between. Fix this. Signed-off-by: Simon Glass

dtoc: Add a way to create an Fdt object from a data block

2018-09-28T17:09:01Z

Support creating an Fdt object without having to write the data to a file first. Signed-off-by: Simon Glass

dtoc: Add methods for adding and updating properties

2018-09-28T17:09:01Z

Add a few more functions which allow creating and modifying property values. If only we could do this so easily in the real world. Signed-off-by: Simon Glass

dtoc: Support adding new nodes

2018-09-28T17:09:01Z

Add a way to add new nodes and sync them back to the blob. Signed-off-by: Simon Glass

dtoc: Allow syncing of the device tree back to a file

2018-09-28T17:09:01Z

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.

libfdt: Update to latest pylibfdt implementation

2018-08-08T11:49:36Z

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. Signed-off-by: Simon Glass

dtoc: Add a function to obtain a list of phandles

2018-08-01T22:30:48Z

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. Signed-off-by: Simon Glass

dtoc: Export the _FindNode() function

2018-08-01T22:30:48Z

This is useful for clients that want to find a node. Export it so it can be used by others. Signed-off-by: Simon Glass

binman: Add an entry filled with a repeating byte

2018-08-01T22:30:48Z

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. Signed-off-by: Simon Glass
