libfdt: Drop -FDT_ERR_TOODEEP

2017-07-10T12:39:24+00:00

This error code has not been upstreamed and is not really needed since it
is unlikely to be triggered. Drop it to maintain compatability with
upstream.

fdt: Stop building the old python libfdt module

2017-06-02T16:18:19+00:00

This is no-longer needed, so stop building it.

fdt: Rename existing python libfdt module

2017-06-02T16:16:47+00:00

Now that this module has been accepted upstream we should stop using the
local U-Boot one. In preparation for this, rename it to indicate it is for
legacy use.

fdt: Allow swig options to be provided by Makefile

2017-06-02T16:16:47+00:00

U-Boot needs to provide some swig include directories. Add this feature.

fdt: Move header files into lib/libfdt

2017-06-02T16:16:46+00:00

These header files are actually part of libfdt. Move them there to make
it easier to build pylibfdt and easier to merge changes from upstream.

Update the license header to use SPDX at the same time.

fdt: Add Python bindings

2017-06-02T16:16:46+00:00

An early version of this is available upstream. Bring it in as a starting
point. This is from dtc upstream commit e56f2b0.

Future work will plumb it into dtoc and remove the now-unnecessary local
libraries.

fdtgrep: Cope with the /aliases node being last

2017-04-13T20:43:31+00:00

With skeleton.dtsi being dropped it is more likely that the /aliases node
will be last in the device tree. Update fdtgrep to handle this.

libfdt: fix build with Python 3

2017-04-10T19:25:19+00:00

For some reason Python 3 seems to think it does not need to build
the library. Using the --force parameter makes sure that the library
gets built always. This is especially important since we move the
library in the next step of the Makefile, hence forcing a rebuild
every time the higher level Makefile triggers a rebuild is required
to make sure the library is always there.

libfdt: Correct fdt handling of overlays without fixups and base trees without symbols

2017-01-14T01:19:45+00:00

The fdt_overlay_apply() function purports to support the edge cases where
an overlay has no fixups to be applied, or a base tree which has no
symbols (the latter can only work if the former is also true).  However it
gets it wrong in a couple of small ways:

  * In the no fixups case, it doesn't fail immediately, but will attempt
    fdt_for_each_property_offset() giving -FDT_ERR_NOTFOUND as the node
    offset, which will fail.  Instead it should succeed immediately, since
    there's nothing to do.
  * In the case of no symbols, it again doesn't fail immediately.  However
    if there is an actual fixup it will fail with an unexpected error,
    because -FDT_ERR_NOTFOUND is passed to fdt_getprop() when attempting to
    look up the symbols.  We should instead return -FDT_ERR_NOTFOUND
    directly.

Both of these errors lead to the code returning misleading error codes in
failing cases.
