Merge branch 'master' into u1e_newbuild
Made so Makefile changes as well to get it to build * master: new make works on ise12 produces good bin files first attempt at cleaning up the build system get rid of debug stuff to help timing move u2_core into u2_rev3 directory to simplify directory structure and save headaches Conflicts: usrp2/fifo/fifo36_to_fifo18.v usrp2/top/u2_rev3/Makefile usrp2/top/u2_rev3/Makefile.udp usrp2/top/u2_rev3/u2_core_udp.v
