With some further tests that is not absolutely necessary like I first thought. The raspberry bootloader has a configuration option for setting the start address: If the following line is added to the config.txt we can leave the address at 0x00200000:
kernel_address=0x00200000 See https://www.raspberrypi.org/documentation/configuration/config-txt/boot.md for details regarding the config.txt. I tested it on a Pi 1 and it works there. I'm still trying to find another bug so it will need some time till I can test it on a Pi 2.
