- Disable all bits in SIC_IWR unless we are going into a real (DPMC) power saving mode. Any Interrupt can wake the core form it's idle state. - Remove deep sleep mode as it is not going to be used anywhere: We support sleep, sleep deeper and hibernate.

- allow people to select the feature that is unavailable to the kernel: NMI, JTAG, or CYCLES. - change default NMI handler to simply dump hardware trace buffer. - remove default NMI handler completely as calling into kernel code is not safe move example handler to wiki so people dont haphazardly copy and paste this stuff thinking its safe Signed-off-by: NMike Frysinger <michael.frysinger@analog.com> Signed-off-by: NBryan Wu <bryan.wu@analog.com>

revise anomaly handling by basing things on the compiler not the kconfig defines, so the header is stable and usable outside of the kernel. This also allows us to move some code from preprocessing to compiling (gcc culls dead code) which should help with code quality (readability, catch minor bugs, etc...).

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: NBryan Wu <bryan.wu@analog.com> Signed-off-by: NMariusz Kozlowski <m.kozlowski@tuxland.pl> Signed-off-by: NAubrey Li <aubrey.li@analog.com> Signed-off-by: NJie Zhang <jie.zhang@analog.com> Signed-off-by: NAndrew Morton <akpm@linux-foundation.org> Signed-off-by: NLinus Torvalds <torvalds@linux-foundation.org>
