Hi,

This is the patch to add cortex-m52 in the Arm-related options
sections of the gcc invoke.texi documentation.

Is it OK for trunk?

Regards,

In the ChangeLog entry:
gcc/ChangeLog:

	* doc/invoke.texi: Update docs.

Let's be more specific and specify something like
	* doc/invoke.texi (Arm Options): Document Cortex-m52 options.

Ok with a better ChangeLog entry.
Thanks,
Kyrill
