Until now the rt-loader only works on U-Boot driven devices where the environment (e.g. coprocessor) is usually setup properly. Devices like the ZyXEL GS1920 series use BootBase as start environment and skip some of the basic initialization steps. rt-loader will fail in these cases. Take care about the CP0 registers. Additionally enhance the documentation of the printf implementation. It was optimized during the different revisions of the initial PR.
