gfxml2dto: Add the gfxml2dto tool
To convert the Garz & Fricke specific XML files to the more general Device Tree overlay files a tool is needed.
This tool is called gfxml2dto. It is capable of reading the G&F XML file (by default located in /etc/shared/config.xml) and converting some of the parts to device tree overlay blobs.
These blobs together with a base device tree can be used to generate a
system specific device tree. The base device tree needs to be created
including the symbols. (This is achieved by using the "-@" flag when
using the dtc
tool.)
We currently have no versioning applied to gfxml2dto.
Add this gfxml2dto to the MACHINE_EXTRA_RRECOMMENDS to install it in images using this machine layer.
