Subject: [PATCH 3.12 173/212] cpufreq: highbank-cpufreq: Enable Midway/ECX-2000

3.12-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Mark Langsdorf <mark.langsdorf@...xeda.com>

commit fbbc5bfb44a22e7a8ef753a1c8dfb448d7ac8b85 upstream.

Calxeda's new ECX-2000 part uses the same cpufreq interface as highbank,
so add it to the driver's compatibility list.

This is a minor change that can safely be applied to the 3.10 and 3.11
stable trees.
