Add overlaycheck2 - #206

ovmerge.py is a reimplementation of ovmerge in Python. It should be identical, output-wise, compared to the Perl original. To enable the creation of related tools, the parsing and DT manipulation parts of the utility have been placed in ovmerge_engine.py. Signed-off-by: Phil Elwell <phil@raspberrypi.com>

Moving form perl to python is a big plus for me. Does overlaycheck2 miss any functionality over overlaycheck? |

overlaycheck2 is a full, drop-in replacement for overlaycheck. It returns identical results, except for the additional error it found. And yes, the plan is to replace overlaycheck with the new version. |
Reinvent overlaycheck as a Python utility that, for the most part, replaces the pairing of ovmerge as a preprocessor and separate passes for each test with the internalisation of the DT as a data structure on which the various checkers work. The end result has been a new bug found (apds9660 wasn't referencing its pinctrl node) and a two thirds reduction in run time. Signed-off-by: Phil Elwell <phil@raspberrypi.com>
