2011-07-23	Blackfin: dpmc: optimize hibernate/resume path	Mike Frysinger	1	-1/+0
	The current save logic used in hibernation is to do a MMR load (base + offset) into a register, and then push that onto the stack. Then when restoring, pop off the stack into a register followed by a MMR store (base + offset). These use plenty of 32bit insns rather than 16bit, are pretty long winded, and full of pipeline bubbles. So, by taking advantage of MMRs that are contiguous, the multi-register push/pop insn, and register abuse, we can shrink this code considerably. When saving, the new logic does a lot of loads into the data and pointer registers before executing a single multi-register push insn. Then when restoring, we do a single multi-register pop insn followed by a lot of stores. Overall, this allows us to cut the insn count by ~30%, the code size by ~45%, and drastically reduce the register hazards that trigger bubbles in the pipeline.

2011-07-23	Blackfin: dpmc: relocate hibernate helper macros	Mike Frysinger	1	-26/+0
	This defines only get used in the hibernate code, so remove them from the global dpmc header as no one else cares. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2011-03-18	Blackfin: SMP: implement cpu_freq support	Graf Yang	1	-0/+3
	Re-use some of the existing cpu hotplugging code in the process. Signed-off-by: Graf Yang <graf.yang@analog.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2011-01-10	Blackfin: dpmc.h: pull in new pll.h	Mike Frysinger	1	-0/+2
	Any consumer of dpmc.h expects to use VR_CTL, so also pull in the new mach/pll.h header for those functions. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2010-03-09	Blackfin: eat spurious space in asm/dpmc.h	Mike Frysinger	1	-2/+2

2009-10-07	Blackfin: mass clean up of copyright/licensing info	Robin Getz	1	-2/+4
	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).
