arch: remove blackfin port

2018-03-16T09:55:47Z

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: SMP: fix build breakage in cache.h

2011-01-10T12:18:14Z

The SMP code needs "asmlinkage" which linkage.h provides. Signed-off-by: Mike Frysinger

dma-mapping: rename ARCH_KMALLOC_MINALIGN to ARCH_DMA_MINALIGN

2010-08-11T15:59:21Z

Now each architecture has the own dma_get_cache_alignment implementation. dma_get_cache_alignment returns the minimum DMA alignment. Architectures define it as ARCH_KMALLOC_MINALIGN (it's used to make sure that malloc'ed buffer is DMA-safe; the buffer doesn't share a cache with the others). So we can unify dma_get_cache_alignment implementations. This patch: dma_get_cache_alignment() needs to know if an architecture defines ARCH_KMALLOC_MINALIGN or not (needs to know if architecture has DMA alignment restriction). However, slab.h define ARCH_KMALLOC_MINALIGN if architectures doesn't define it. Let's rename ARCH_KMALLOC_MINALIGN to ARCH_DMA_MINALIGN. ARCH_KMALLOC_MINALIGN is used only in the internals of slab/slob/slub (except for crypto). Signed-off-by: FUJITA Tomonori Cc: Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

Blackfin: set ARCH_KMALLOC_MINALIGN

2010-05-22T18:19:13Z

Architectures that handle DMA-non-coherent memory need to set ARCH_KMALLOC_MINALIGN to make sure that kmalloc'ed buffer is DMA-safe: the buffer doesn't share a cache with the others. Signed-off-by: FUJITA Tomonori Acked-by: Pekka Enberg Signed-off-by: Mike Frysinger

Blackfin: mass clean up of copyright/licensing info

2009-10-07T08:36:26Z

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: decouple unrelated cache settings to get exact behavior

2009-06-23T01:15:59Z

The current cache options don't really represent the hardware features. They end up setting different aspects of the hardware so that the end result is to turn on/off the cache. Unfortunately, when we hit cache problems with the hardware, it's difficult to test different settings to root cause the problem. The current settings also don't cleanly allow for different caching behaviors with different regions of memory. So split the configure options such that they properly reflect the settings that are applied to the hardware. Signed-off-by: Jie Zhang Signed-off-by: Mike Frysinger
