Subject: [U-Boot] [PATCH 14.5/15] tegra: Keep virt support disabled by default
Date: Fri, 17 Apr 2015 08:56:55 +0200 [thread overview]
Message-ID: <5530AEB7.4030202@siemens.com> (raw)
In-Reply-To: <cover.1428900500.git.jan.kiszka@siemens.com>
Upstream Linux is broken with default configs when PSCI is enabled.
So the user should explicitly enable virtualization, e.g. when she
disabled CONFIG_CPU_IDLE in Linux (in which case it's safe to use). We
can revert this workaround once Linux got fixed.
