[U-Boot] [PATCH 0/9] Add PSCI support for Jetson TK1/Tegra124

[Jan Kiszka]

I've picked up Ian's and Thierry's work on PSCI support for Tegra124,
specifically the Jetson TK1 board. This series contains Ian's patches
and a rewritten version of the PSCI core as suggested by Thierry. It's
working fine on the TK1, allowing Linux to online/offline CPUs 1-3 as
it likes (provided CONFIG_CPU_IDLE is off).

Patches are also available here:

Looking forward to review.
