Modify the code to make it usable by both Python versions. print_function is available in __future__ since Python 2.6.0a2, which shouldn't be a relevant restriction. The modified script generates the same documentation as the old one; independent if the script is called using Python 2 (here: 2.7.16) or Python 3 (here: 3.7.3).

Disabling the internal reset handling (similar to what's done on the i.MX7 Sabre boards) allowed barebox to download and run successfully.

Dumping target information showed that vf610.cpu1 was the active target, rather that vf610.cpu0. Adding a command prior to the halt to explicitly set the target core resulted in proper operation.
