From mboxrd@z Thu Jan 1 00:00:00 1970 From: Anton Vorontsov Date: Thu, 15 Oct 2009 17:47:04 +0400 Subject: [U-Boot] [PATCH 1/7] fdt_support: Add multi-serial support for stdout fixup In-Reply-To: <20091015134644.GA31541@oksana.dev.rtsoft.ru> References: <20091015134644.GA31541@oksana.dev.rtsoft.ru> Message-ID: <20091015134704.GA32478@oksana.dev.rtsoft.ru> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: u-boot@lists.denx.de Currently fdt_fixup_stdout() is using hard-coded CONFIG_CONS_INDEX constant. With multi-serial support, the CONS_INDEX may no longer represent actual console, so we should try to extract port number from the current stdio device name instead of always hard-coding the constant value.
