From mboxrd@z Thu Jan 1 00:00:00 1970 From: Daniel Mack Date: Mon, 8 Jun 2009 16:58:00 +0200 Subject: [Buildroot] [PATCH 2/2] Add target support for MXC based devices In-Reply-To: <1244473080-8195-1-git-send-email-daniel@caiaq.de> References: <1244473080-8195-1-git-send-email-daniel@caiaq.de> Message-ID: <1244473080-8195-2-git-send-email-daniel@caiaq.de> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: buildroot@busybox.net Devices based on Freescale's MXC SoCs need some extra attention to start the gettys from init. In particular, the /dev/ttymxc0 inode needs to be created and added to inittab and securetty.
