Subject: [PATCH 2/4] arm: psci: enable PSCI on UP systems
Date: Wed, 8 Jul 2015 18:13:35 +0800	[thread overview]
Message-ID: <1436350417-6712-3-git-send-email-jszhang@marvell.com> (raw)
In-Reply-To: <1436350417-6712-1-git-send-email-jszhang@marvell.com>

The PSCI can work on both SMP and UP. Now We'd like to enable PSCI
features on UP systems. This is to prepare for next commit to implement
cpuidle_ops with PSCI functions.
