From mboxrd@z Thu Jan 1 00:00:00 1970 From: Kinsella, Ray Date: Fri, 16 Oct 2015 16:27:36 +0000 Subject: [Buildroot] [RFC] Buildroot support for X1000 Message-ID: <1445012855.1856.6.camel@intel.com> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: buildroot@busybox.net Hi Arnout, X1000 is the Intel microprocessor that ships with Intel Galileo Gen 1/2. As discussed previously, here is an RFC that prototypes changes to arch and toolchain-wrapper to omit the lock prefix for the X1000. If you agree, I will send a formal patch with these.
