Subject: [U-Boot] [PATCH v3 07/28] ppc: Add initial memory barrier macros
Date: Thu, 16 Feb 2012 06:48:54 -0800 [thread overview]
Message-ID: <1329403755-6396-8-git-send-email-sjg@chromium.org> (raw)
In-Reply-To: <1329403755-6396-1-git-send-email-sjg@chromium.org>
These are available on other architectures, so add them on ppc.
