Subject: [PATCH v3 1/2] arm: Convert v7 proc infos into a common macro
Date: Fri, 20 May 2011 14:39:28 +0100 [thread overview]
Message-ID: <1305898769-10462-1-git-send-email-pawel.moll@arm.com> (raw)
In-Reply-To: <1305892312.17656.72.camel@hornet.cambridge.arm.com>
As most of the proc info content is common across all v7
processors, this patch converts existing A9 and generic v7
descriptions into a macro (allowing extra flags in future).
