A single percent sign might be interpreted as a string format directive
and shall thus be escaped - doubling it - to actually indicate a
percentage.
Without the escape, pytest fails to run test_fdt.py with the following
error:
ValueError: Test coverage failure

It generates header files containing struct definitions, as well as C files containing the data. It does not require any modification of the devicetree files. Some high-level libraries are provided for working with devicetree. These may be useful in other projects. This package also includes some U-Boot-specific features, such as creating `struct udevice` and `struct uclass` entries for devicetree nodes.
