Subject: [PATCH v2] ARM: Add HAVE_CACHE_L2X0
Date: Fri, 11 Jun 2010 23:13:17 -0500 [thread overview]
Message-ID: <20100612041317.GA23571@lixom.net> (raw)
In-Reply-To: <1276279087.31800.6.camel@c-dwalke-linux.qualcomm.com>
It normally scales better if each platform that has <foo> selects the
HAVE_<foo> option, instead of having to add every single one to the
depends line for CONFIG_<foo>.

Ah, I missed it. I'm not attached to the option name so since I didn't
see you repost, here's my version... :)
