Blackfin: SMP: work around anomaly 05000491

2011-03-18T08:01:04+00:00

In order to safely work around anomaly 05000491, we have to execute IFLUSH from L1 instruction sram. The trouble with multi-core systems is that all L1 sram is visible only to the active core. So we can't just place the functions into L1 and call it directly. We need to setup a jump table and place the entry point in external memory. This will call the right func based on the active core. In the process, convert from the manual relocation of a small bit of code into Core B's L1 to the more general framework we already have in place for loading arbitrary pieces of code into L1.

Blackfin: rewrite resync_core_{i,d}cache() SMP logic to avoid per_cpu data

2010-03-09T05:30:50+00:00

This functions are implicitly called by core functions like cpu_relax(), and since those functions may be called early on before common code has initialized the per-cpu data area, we need to tweak the stats gathering. Now the statistics are maintained in common bss which makes these funcs safe to use as soon as the C runtime env is setup. Signed-off-by: Graf Yang Signed-off-by: Mike Frysinger

Blackfin: mass clean up of copyright/licensing info

2009-10-07T08:36:26+00:00

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).
