Subject: [PATCH 5/5] ARM: iwmmxt: allow to build iWMMXt on Marvell PJ4B
Date: Tue, 15 Apr 2014 20:16:03 +0200	[thread overview]
Message-ID: <1397585763-23482-6-git-send-email-sebastian.hesselbarth@gmail.com> (raw)
In-Reply-To: <1397585763-23482-1-git-send-email-sebastian.hesselbarth@gmail.com>

Some Marvell PJ4B CPUs also implement iWMMXt extensions. With a
proper check for iWMMXt coprocessors now in place, enable it by
default on PJ4B. While at it, also allow to manually select
the corresponding Kconfig option.
