arch: remove blackfin port

2018-03-16T09:55:47+00:00

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/ipipe: fix deferred pipeline sync for the root stage

2011-03-18T08:01:11+00:00

This patch makes sure to sync the pipeline for the root stage only from the outer interrupt level, when resuming kernel code after an interrupt. This fixes a bug causing EVT15 to be spuriously popped off upon nested interrupts, which in turn would cause the preempted kernel code to resume without supervisor privileges.

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).

Blackfin: workaround anomaly 05000283

2009-09-17T02:10:34+00:00

Make sure our interrupt entry code with exact hardware errors handles anomaly 05000283 (infinite stall in system MMR kill) so we don't stall while under load. Signed-off-by: Robin Getz Signed-off-by: Mike Frysinger
