Version 2 introduces CPU-local target PC (power-up vector), as pointed out by Chen-Yu. It also includes a new patch to properly set CNTFRQ on all Tegra124 CPUs, not only CPU0. This finally allows to run KVM guests on TK1. The series was tested on the Banana Pi as well.
The patches are also available here:
