WOW! Answered in less than 5 minutes!!
I have one more rookie-question left:
I placed the missing commands in the LDF between the VDSG like listed below and i'm able to compile/link without warnings or error now. Do i have to uncomment the VDSG block in some way? For me this looks like a comment and not program code...
/*$VDSG<insert-input-sections-at-the-start-of-l1_code> */
/* Text inserted between these $VDSG comments will be preserved */
INPUT_SECTIONS($OBJECTS(adi_fast_prio0_code)) // missing comment
/*$VDSG<insert-input-sections-at-the-start-of-l1_code> */
