The code is tested on da8xx (the AM1808 I tested it on is part of the
da8xx family) but as I didn't yet look into loading an u-boot image
from SPI flash (which I should do here for the da850evm) I just call
hang() here. I commented on this in the cover message:

---snip---
This patchset is not a complete implementation, it is missing the
code that is actually used to load u-boot from SPI flash to the
DDR memory. The code just hangs after the initialization is done. But
I submit it nevertheless as RFC and I am looking forward to your comments.
