Hi Lukas You don't need to take special care for RedBoot during porting process. Simple "hello world" application is enough, and for me more convenient, to get hal_diag in order. Once you have hal_diag (and of course clocking and basic configuration) RedBoot should compile and run without problems. Then, once you add Ethernet driver, you should be able to telnet to RedBoot.
