In-Reply-To: <1365761909-15305-1-git-send-email-sonic.adi@gmail.com> References: <1365761909-15305-1-git-send-email-sonic.adi@gmail.com> Message-ID: <1365761909-15305-3-git-send-email-sonic.adi@gmail.com> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: buildroot@busybox.net From: Sonic Zhang Adds the possibility to have a free-form CPU revision string and append it to the target CPU. Only Blackfin actually uses this option.
