[U-Boot] [PATCH v2 00/12] Add PSCI support for Jetson TK1/Tegra124 + CNTFRQ fix

[Jan Kiszka]

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:
