At present we have two separate implementations of the Fdt library, one which uses fdtget/fdtput and one which uses libfdt (via swig). Before adding more functionality it makes sense to create a base class for these. This will allow common functions to be shared, and make the Fdt API a little clearer. Create a new fdt.py file with the base class, and adjust fdt_normal.py and fdt_fallback.py to use it. Signed-off-by: Simon Glass <sjg@chromium.org>
