* arch: remove blackfin portArnd Bergmann2018-03-16
| | | | | | | | | | | | | | | | | | | The Analog Devices Blackfin port was added in 2007 and was rather active for a while, but all work on it has come to a standstill over time, as Analog have changed their product line-up. Aaron Wu confirmed that the architecture port is no longer relevant, and multiple people suggested removing blackfin independently because of some of its oddities like a non-working SMP port, and the amount of duplication between the chip variants, which cause extra work when doing cross-architecture changes.

* Blackfin: dpmc: optimize hibernate/resume pathMike Frysinger2011-07-23
| | | | | | | | | | | | | | | | | | | | 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.

* Blackfin: mass clean up of copyright/licensing infoRobin Getz2009-10-07
| | | | | | | | | | | | | | | | | | 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).
