[OpenWrt-Devel] [RFC] commit message in YAML format for new devices

[Paul Spooren]

Hi all,

I looked a bit into parsing the DeviceTree files but it's a bit of a 
pain. Tools like dts2yaml and dtc exists, however the output is not 
really useful: A lot of auto detection prevents the parser from knowing 
flash & storage sizes or number of USB ports.

Therefore I decided to create a simple shell script to get all relevant 
information. I'd add it to ./scripts/, maybe there is a simple way with 
Makefile integration as well like Petr suggested.

Next mail will contain some patch.

If anybody wants to continue the DeviceTree approach, dts2yaml creates 
links pointing to files outside the OpenWrt sources, meaning the Python 
YAML libs fails to read it due to missing anchors. Converting dtb files 
via dtc works however, just be aware that you have to convert it from 
dtb to dts first and in a second run from dts to yaml. Single step is 
not supported.

Best,
Paul
