Subject: [PATCH] arm64: tegra: Enable all cores on Jetson TX1
Date: Thu, 30 Jun 2016 17:01:19 +0900 [thread overview]
Message-ID: <20160630080119.27090-1-acourbot@nvidia.com> (raw)
Enable PSCI firmware and all 4 cores of T210 on Jetson TX1.
Signed-off-by: Alexandre Courbot <acourbot@nvidia.com>

Not sure why this was not done - in any case this seems to work fine
and performance is obviously improved (especially boot time).
