Subject: [PATCH 3/6] powerpc: Remove powerpc specific cmd_line
Date: Wed, 17 Sep 2014 14:39:36 +1000 [thread overview]
Message-ID: <1410928779-20938-3-git-send-email-anton@samba.org> (raw)
In-Reply-To: <1410928779-20938-1-git-send-email-anton@samba.org>
There is no need for yet another copy of the command line, just
use boot_command_line like everyone else.
