Blackfin: mass clean up of copyright/licensing info Bill Gatliff & David Brownell pointed out we were missing some copyrights, and licensing terms in some of the files in ./arch/blackfin, so this fixes things, and cleans them up. It also removes: - verbose GPL text(refer to the top level ./COPYING file) - file names (you are looking at the file) - bug url (it's in the ./MAINTAINERS file) - "or later" on GPL-2, when we did not have that right It also allows some Blackfin-specific assembly files to be under a BSD like license (for people to use them outside of Linux).

Blackfin: SMP: make core timers per-cpu clock events for HRT SMP systems require per-cpu local clock event devices in order to enable HRT support. One a BF561, we can use local core timer for this purpose. Originally, there was one global core-timer clock event device set up for core A. To accomplish this feat, we need to split the gptimer0/core timer logic so that each is a standalone clock event. There is no requirement that we only have one clock event source anyways. Once we have this, we just define per-cpu clock event devices for each local core timer. Signed-off-by: Yi Li <yi.li@analog.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
