From 1394f03221790a988afc3e4b3cb79f2e477246a9 Mon Sep 17 00:00:00 2001 From: Bryan Wu Date: Sun, 6 May 2007 14:50:22 -0700 Subject: blackfin architecture 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 Signed-off-by: Mariusz Kozlowski Signed-off-by: Aubrey Li Signed-off-by: Jie Zhang Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds --- fs/Kconfig.binfmt | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'fs/Kconfig.binfmt') diff --git a/fs/Kconfig.binfmt b/fs/Kconfig.binfmt index f3d3d81eb7e..74c64409ddb 100644 --- a/fs/Kconfig.binfmt +++ b/fs/Kconfig.binfmt @@ -26,7 +26,7 @@ config BINFMT_ELF config BINFMT_ELF_FDPIC bool "Kernel support for FDPIC ELF binaries" default y - depends on FRV + depends on (FRV || BLACKFIN) help ELF FDPIC binaries are based on ELF, but allow the individual load segments of a binary to be located in memory independently of each -- cgit v1.2.3
