2023-02-05pylibfdt: add size_hint parameter for get_path Luca Weiss
This also enables us to test the -NOSPACE condition by adding a test setting size_hint=1 so this path is taken. Message-Id: <20230201181112.1644842-1-luca@z3ntu.xyz> Signed-off-by: Luca Weiss <luca@z3ntu.xyz> Signed-off-by: David Gibson <david@gibson.dropbear.id.au>

2019-11-15pylibfdt: Adjust for deprecated test methods Simon Glass
Python recently deprecated some test methods in favour of others. Adjust the code to avoid warnings. Signed-off-by: Simon Glass <sjg@chromium.org> Message-Id: <20191113012410.62550-1-sjg@chromium.org> Signed-off-by: David Gibson <david@gibson.dropbear.id.au>
2019-10-27pylibfdt: Correct the type for fdt_property_stub() Simon Glass
This function should use a void * type, not char *. This causes an error: TypeError: in method 'fdt_property_stub', argument 3 of type 'char const *' Fix it and update the tests.

2018-11-23tests: Use modern octal literals for Python David Gibson
Python3 removes support for C-style octal literals, using 0oXXXX instead. Python2 also supports this form, so move to the new style. Reported-by: Lumir Balhar <lbalhar@redhat.com> Signed-off-by: David Gibson <david@gibson.dropbear.id.au>
2018-09-13pylibfdt: Add a means to add and delete notes Simon Glass
These methods are needed to permit larger changes to the device tree blob. Add two new methods and an associate test. Signed-off-by: Simon Glass <sjg@chromium.org> Signed-off-by: David Gibson <david@gibson.dropbear.id.au>
2018-07-11pylibfdt: Support the sequential-write interface Simon Glass
It is useful to be able to create a device tree from scratch using software. This is supported in libfdt but not currently available in the Python bindings. Add a new FdtSw class to handle this, with various methods corresponding to the libfdt functions. When the tree is complete, calling AsFdt() will return the completed device-tree object.

2018-06-14pylibfdt: Add functions to set and get properties as strings Simon Glass
It is common to want to set a property to a nul-terminated string in a device tree. Add python methods to handle this. Signed-off-by: Simon Glass <sjg@chromium.org> Signed-off-by: David Gibson <david@gibson.dropbear.id.au>
2018-06-13pylibfdt: Update the bytearray size with pack() Simon Glass
At present pack() calls fdt_pack() which may well reduce the size of the device-tree data. However this does not currently update the size of the bytearray to take account of any reduction. This means that there may be unused data at the end of the bytearray and any users of as_bytearray() will see this extra data. Fix this by resizing the bytearray after packing.

2018-06-13pylibfdt: Allow reading integer values from properties Simon Glass
Extend the Properties class with some functions to read a single integer property. Add a new getprop_obj() function to return a Property object instead of the raw data. This suggested approach can be extended to handle other types, as well as arrays. Signed-off-by: Simon Glass <sjg@chromium.org> Signed-off-by: David Gibson <david@gibson.dropbear.id.au>

2018-06-09pylibfdt: Support device-tree creation/expansion Simon Glass
Add support for fdt_open_into() and fdt_create_empty_tree() from the Python library. The former is named resize() since it better fits with what the Python binding actually does. Signed-off-by: Simon Glass <sjg@chromium.org> Signed-off-by: David Gibson <david@gibson.dropbear.id.au>

2018-06-08pylibfdt: Add support for fdt_next_node() Simon Glass

2018-06-04Make Property a subclass of bytearray Simon Glass
It is annoying to have to add .value when we want the value of a Property. Make Property a subclass of bytearray so that it can be used directly when the value is required. Fix the Property class comment while we are here.

2018-06-04pylibfdt: Add a method to access the device tree directly Simon Glass
When calling libfdt functions which are not supported by the Fdt class it is necessary to get direct access to the device tree data. At present this requries using the internal _fdt member. Add a new method to provide public access to this, without allowing the data to be changed. Note that a bytearray type is returned rather than str, since the swig types are set up for bytearray to map correctly to const void *.

2017-08-21pylibfdt: Use local pylibfdt module Simon Glass
Some systems may have the Python libfdt.py library installed. Adjust the tests to prepend the local libfdt path so that we test the local version instead of the system version. Signed-off-by: Simon Glass <sjg@chromium.org> Signed-off-by: David Gibson <david@gibson.dropbear.id.au>
2017-08-21pylibfdt: Add a test for use of uint32_t Simon Glass
