From mboxrd@z Thu Jan 1 00:00:00 1970 From: Hannes Petermaier Date: Fri, 30 Jan 2015 14:25:15 +0100 Subject: [U-Boot] [PATCH 12/21] board/BuR/common: Introduce Network Console and common environment for it In-Reply-To: <1422624324-15431-1-git-send-email-oe5hpm@oevsv.at> References: <1422624324-15431-1-git-send-email-oe5hpm@oevsv.at> Message-ID: <1422624324-15431-12-git-send-email-oe5hpm@oevsv.at> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: u-boot@lists.denx.de It is often necessary to "break in" into boards bootloader commandline if something fails or even for development purposes some parameters have to be changed. So we enable u-boot's CONFIG_NETCONSOLE feature. We also modify Networksettings to apply with this new use-case.
