Is the above part necessary since SPL_OF_CONTROL is defined? I know the da850evm doesn't need this anymore and I was able to remove it when converting to SPL_OF_CONTROL.

Hi Adam,
we discussed it last time[1]: I tried to follow your example but got stuck on a nasty build error and we agreed to merge it in this form and try to improve it later.
I hope you're still ok with that.
