Hello,

This simple patch is to enable GCC to accept new option -mcpu=cortex-m0plus
in order to support newly released Cortex-M0+. Is it OK to trunk, 4.7 branch
and 4.6 branch?

BR,
Terry

2012-04-06  Terry Guo  <terry.guo@arm.com>

        * config/arm/arm-cores.def: Added core cortex-m0plus.
        * config/arm/arm-tune.md: Regenerated.
        * config/arm/arm-tables.opt: Regenerated.
        * doc/invoke.texi: Added entry for cpu ARM Cortex-M0PLUS.

This is ok for trunk only.  It's not suitable for the release branches
as it is a new feature.
