From bbf28b505ac2dd923b9051ca5031cf87bf7c40cc Mon Sep 17 00:00:00 2001 From: Rob Herring Date: Mon, 26 Aug 2013 11:28:50 -0500 Subject: openrisc: use boot_command_line instead of private cmd_line Save some pointless copying of the kernel command line and just use boot_command_line instead. The DT code already handles CONFIG_CMDLINE, so a separate copy is not needed.
