Subject: [PATCH 2/5] omap4: Enable ARM local timers with OMAP4430 es1.0 exception
Date: Sat, 12 Feb 2011 16:59:44 +0530	[thread overview]
Message-ID: <1297510187-31547-3-git-send-email-santosh.shilimkar@ti.com> (raw)
In-Reply-To: <1297510187-31547-1-git-send-email-santosh.shilimkar@ti.com>

On OMAP4430 ES1.0 the local timers are gated by security. Enable the
CONFIG_LOCAL_TIMERS for omap2plus build and handle the OMAP4430 es1.0
exception case.

This patch has dependency on the first patch in this series.
