From 312717f15ac7095c3ea98d487276781535ca7c0b Mon Sep 17 00:00:00 2001 From: Rob Herring Date: Sun, 25 Aug 2013 18:29:51 -0500 Subject: c6x: use boot_command_line instead of private c6x_command_line Save some pointless copying of the kernel command line and just use boot_command_line instead. Also remove default_command_line as it is not referenced anywhere, and the DT code already handles the default command line.
