[Alex Coplan]

[-- Attachment #1: Type: text/plain, Size: 638 bytes --]

This patch adds support for Arm's Cortex-R82 CPU to GCC. For more
information about this CPU, see [0].

Testing:
 * Bootstrapped and regtested on aarch64-none-linux-gnu, no regressions.

[0] : https://developer.arm.com/ip-products/processors/cortex-r/cortex-r82

OK for trunk?

gcc/ChangeLog:

	* config/aarch64/aarch64-cores.def: Add Cortex-R82.
	* config/aarch64/aarch64-tune.md: Regenerate.
	* doc/invoke.texi: Add entry for Cortex-R82.
