Subject: [PATCH v4 1/5] xen/arm: earlyprintk: move early_flush in early_puts
Date: Thu, 13 Mar 2014 15:09:14 +0000 [thread overview]
Message-ID: <1394723358-22845-2-git-send-email-julien.grall@linaro.org> (raw)
In-Reply-To: <1394723358-22845-1-git-send-email-julien.grall@linaro.org>
early_puts function will be exported to be used in the console code. To
avoid loosing characters (see why in commit cafdceb "xen/arm: avoid lost
characters with early_printk), early_flush needs to be called in this
function.
