Subject: [PATCH v4 2/2] arm: prefer PSCI for SMP bringup
Date: Fri, 29 Mar 2013 16:42:50 +0000 [thread overview]
Message-ID: <1364575371-8926-2-git-send-email-stefano.stabellini@eu.citrix.com> (raw)
If PSCI initializes correctly and PSCI SMP operations are available, use them.
This is required for SMP support in Dom0 on Xen.
