Also I added a paragraph to the commit log mentioning the development board I used: There are still some missing parts (e.g. board support, device trees), but with these bits added on top of this patch I can successfully boot a EFM32GG-DK3750 board that uses an EFM32GG990F1024. Good enough? Best regards Uwe
