* Blackfin: use more standard pr_fmt in the module loaderJoe Perches2011-03-251-27/+18
| | | | | | | | | | Changed pr_fmt(fmt) to make the format arguments match the format. Changed an argument name in apply_relocate from me to mod so that the pr_err is consistent with the other uses. Added missing '\n' to a format. Signed-off-by: Joe Perches <joe@perches.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* Blackfin: mass clean up of copyright/licensing infoRobin Getz2009-10-071-25/+2
| | | | | | | | | | | | | | | | | | 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 module reloc handling for all memory regionsMike Frysinger2009-09-161-28/+34
| | | | | | | | | The current module relocation code has spotty handling wrt different memory regions (like L1 instruction). Rather than try to fix each little spot, use the new common memory functions to greatly simplify everything and make sure it is always correct. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* Blackfin: cleanup module section checkingMike Frysinger2009-09-161-51/+60
| | | | | | | | | The current module section handling code has a lot of verbose statements copied and pasted throughout which makes it pretty hard to digest at a glance. By unifying all of these up front, it is a lot easier to quickly get an idea of what is actually going on. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

* Blackfin: cleanup printk() usage in module codeMike Frysinger2009-09-161-34/+25
| | | | | | | Convert all printk() statements to use the common pr_xxx() funcs and use the new pr_fmt() function to standardize all of the output. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* Blackfin: reject outdated/unused/wrong relocation typesRobin Getz2009-09-161-34/+8
| | | | | | | | | | | All kernel modules are required to be built with -mlong-calls and thus should not generate any of these relocations. If they do, it means the module has not been compiled properly, so rather than trying to handle them (and running into random run time errors) just error out on module load to force the module to be compiled correctly.

* Blackfin: rename Blackfin relocs according to the toolchainMike Frysinger2009-06-121-11/+11
| | | | | | | | The latest Blackfin toolchain has fixed its relocation scheme to match other ports: always use R_BFIN_ prefix and capitalize everything. This brings the kernel in line with those fixes. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* Blackfin arch: Remove all traces of the relocation stackBernd Schmidt2009-01-071-132/+7
| | | | | | | | | | | | Remove all traces of the relocation stack. It's been removed from binutils for years now. Add a sanity overflow check to pcrel24 relocations to catch modules that were built without -mlong-calls.

* blackfin architectureBryan Wu2007-05-071-0/+429
This adds support for the Analog Devices Blackfin processor architecture, and currently supports the BF533, BF532, BF531, BF537, BF536, BF534, and BF561 (Dual Core) devices, with a variety of development platforms including those avaliable from Analog Devices (BF533-EZKit, BF533-STAMP, BF537-STAMP, BF561-EZKIT), and Bluetechnix! Tinyboards. The Blackfin architecture was jointly developed by Intel and Analog Devices Inc. (ADI) as the Micro Signal Architecture (MSA) core and introduced it in December of 2000. Since then ADI has put this core into its Blackfin processor family of devices. The Blackfin core has the advantages of a clean, orthogonal,RISC-like microprocessor instruction set. It combines a dual-MAC (Multiply/Accumulate), state-of-the-art signal processing engine and single-instruction, multiple-data (SIMD) multimedia capabilities into a single instruction-set architecture. The Blackfin architecture, including the instruction set, is described by the ADSP-BF53x/BF56x Blackfin Processor Programming Reference http://blackfin.uclinux.org/gf/download/frsrelease/29/2549/Blackfin_PRM.pdf The Blackfin processor is already supported by major releases of gcc, and there are binary and source rpms/tarballs for many architectures at: http://blackfin.uclinux.org/gf/project/toolchain/frs There is complete documentation, including "getting started" guides available at: http://docs.blackfin.uclinux.org/ which provides links to the sources and patches you will need in order to set up a cross-compiling environment for bfin-linux-uclibc This patch, as well as the other patches (toolchain, distribution, uClibc) are actively supported by Analog Devices Inc, at: http://blackfin.uclinux.org/ We have tested this on LTP, and our test plan (including pass/fails) can be found at: http://docs.blackfin.uclinux.org/doku.php?id=testing_the_linux_kernel [m.kozlowski@tuxland.pl: balance parenthesis in blackfin header files] Signed-off-by: Bryan Wu <bryan.wu@analog.com> Signed-off-by: Mariusz Kozlowski <m.kozlowski@tuxland.pl> Signed-off-by: Aubrey Li <aubrey.li@analog.com> Signed-off-by: Jie Zhang <jie.zhang@analog.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
