[ARM 3/5 big.LITTLE] Add support for -mcpu=cortex-a15.cortex-a7
2013-12-17 James Greenhalgh <james.greenhalgh@arm.com>
* config/arm/arm-cores.def (cortex-a15.cortex-a7): New.
* doc/invoke.texi: Document -mcpu=cortex-a15.cortex-a7.
* config/arm/arm-tables.opt: Regenerate.
* config/arm/arm-tune.md: Regenerate.
* config/arm/bpabi.h
(BE8_LINK_SPEC): Handle -mcpu=cortex-a5.cortex-a7.
