* Blackfin: make sure mmiowb inserts a write barrier with SSYNCMichael Hennerich2010-08-061-1/+7
| | | | | | | | | Add SSYNC to our implementation of I/O write barrier to ensure ordering of I/O space writes. This will make sure that writes following the barrier will arrive after all previous writes.

* Blackfin: mass clean up of copyright/licensing infoRobin Getz2009-10-071-0/+6
| | | | | | | | | | | | | | | | | | 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: fix warnings with I/O port macrosMike Frysinger2009-06-121-13/+16
| | | | | | | | The I/O port functions take ints, so we need to cast them up before passing to our read/write funcs to avoid ugly messes of warnings. Signed-off-by: Mike Frysinger <vapier@gentoo.org> Signed-off-by: Bryan Wu <cooloney@kernel.org>
