Subject: [PATCH 0/3] Add SMP support for i.MX7D
Date: Fri, 26 Aug 2016 19:12:48 +0800 [thread overview]
Message-ID: <1472209971-32469-1-git-send-email-Anson.Huang@nxp.com> (raw)
i.MX7D has 2 Cortex-A7 ARM cores, and it has a different GPC design
than i.MX6, so this patch set adds a new GPCV2 driver for i.MX7D,
and also adds runtime check in SMP code to support both Cortex-A9
and Cortex-A7 ARM cores.
With this patch set, i.MX7D can boot up SMP kernel with 2 CPUs.
