[Qemu-devel] [PATCH v2 6/6] arm/highbank: enable PSCI emulation support

[Rob Herring <robherring2@gmail.com>]

From: Rob Herring <rob.herring@linaro.org>

Enable PSCI emulation on highbank and midway platforms.

Note that this requires fixing the PSCI function IDs in the DTB to match
what QEMU is using. This should get fixed.

Signed-off-by: Rob Herring <rob.herring@linaro.org>

v2:
- Add error_abort on setting of start-powered-off.
