Hi,

This patch wires up -mcpu=cortex-a57 as an option to
-mcpu. As we don't yet have a scheduling model for Cortex-A57
available, for now we use the scheduling description for another
"big" core, the Cortex-A15.

Bootstrapped in series and sanity checked.

OK?

Thanks,
James

	* config/arm/arm-cores.def (cortex-a57): New.
	* doc/invoke.texi: Document -mcpu=cortex-a57.
	* config/arm/arm-tables.opt: Regenerate.
	* config/arm/arm-tune.md: Regenerate.
	* config/arm/bpabi.h (BE8_LINK_SPEC): Handle -mcpu=cortex-a57.
