Subject: [PATCH 1/2] ARM: Make DEBUG_LL produce CRLF instead of LFCR
Date: Wed, 27 Sep 2017 13:49:28 +0200 [thread overview]
Message-ID: <20170927114929.9259-2-alexander.sverdlin@nokia.com> (raw)
In-Reply-To: <20170927114929.9259-1-alexander.sverdlin@nokia.com>
This change almost doubles the usage of DEBUG_LL macros but
in exchange terminates all the console output with CRLF not LFCR.
Signed-off-by: Alexander Sverdlin <alexander.sverdlin@nokia.com>
