The best thing to do is follow the generic instructions for rebuilding redboot in the on-line RedBoot user's guide at http://sources.redhat.com/ecos/docs-latest/ Unfortunately there is no edb7xxx-specific section yet (Hi Gary :)), but it should just be a case of following the generic instructions, bearing in mind that there are configuration import files at hal/arm/edb7xxx/current/misc which should be used.
