Several weeks ago Intel announced new microarchitecture named Silvermont (see for example http://newsroom.intel.com/community/intel_newsroom/blog/2013/05/06/intel-launches-low-power-high-performance-silvermont-microarchitecture ). This patch is the first and it enables Silvermont architecture in the GCC compiler (second patch will add some performance related features).

I think you should document the newly supported value in gcc/doc/invoke.texi - and probably also mention it in the GCC 4.9's release notes http://gcc.gnu.org/gcc-4.9/changes.html under "New Targets and Target Specific Improvements"
