All,

The attached patch adds support for -mcpu=cortex-a7 to the GCC command line.

A related patch has just been committed to binutils so that gas will 
recognize cortex-a7 on the command line and in the appropriate 
directives.  See http://sourceware.org/ml/binutils/2011-11/msg00048.html.

Can someone please review and comment.

Thanks,

Matt
