Subject[PATCH v2 02/29] openrisc: use boot_command_line instead of private cmd_line
Date
From: Rob Herring <rob.herring@calxeda.com>

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.
