Subject: [PATCH 1/2] arm: omap: sram: fix OMAP4 errata handling
Date: Wed, 29 Aug 2012 18:24:30 +0300 [thread overview]
Message-ID: <1346253871-5761-1-git-send-email-aaro.koskinen@iki.fi> (raw)
OMAP4-specific code should be executed only if we are running on
OMAP4. Otherwise it may break multi-OMAP kernels. Found by reading
the code.
