This implementation is inspired by U-Boot's FIT support. Instead of using libfdt (which does not exist in barebox), configuration signatures are verified by using a simplified DT parser based on barebox's own code. Currently, only signed configurations with hashed images are supported, as the other variants are less useful for verified boot. Compatible FIT images can be created using U-Boot's mkimage tool.
