2007-10-30Blackfin arch: reclaim a few bytes from the end of our init sectionMike Frysinger1-3/+8

2007-08-27Blackfin arch: vmlinux.lds.S, break up our .init into separate sectionsMike Frysinger1-15/+27
Break up our .init into separate section like all other ports do and so that we dont mix text and data (causes disassembly headaches as pointed out by Robin) Cc: Robin Getz <robin.getz@analog.com> Signed-off-by: Mike Frysinger <michael.frysinger@analog.com> Signed-off-by: Bryan Wu <bryan.wu@analog.com>
2007-08-27Blackfin arch: parse input sections properly when using -ffunction-sections/-fdata-sectionsMike Frysinger1-1/+3

2007-07-25Blackfin arch: fix bug which unaligns the init thread's stack and causes the current macro to fail.Bernd Schmidt1-6/+10
switch to using proper defines this time (THREAD_SIZE and PAGE_SIZE) instead of just PAGE_SIZE everywhere Signed-off-by: Mike Frysinger <michael.frysinger@analog.com> Signed-off-by: Bernd Schmidt <bernd.schmidt@analog.com> Signed-off-by: Bryan Wu <bryan.wu@analog.com>
2007-07-12Blackfin arch: use PAGE_SIZE when doing aligns rather than hardcoded valuesMike Frysinger1-5/+7

2007-06-11Blackfin arch: redo our linker script a bitMike Frysinger1-111/+56
- we can start taking advantages of defines in asm-generic/vmlinux.lds.h - move our L1 relocated sections into init so it gets freed after relocation Signed-off-by: Mike Frysinger <michael.frysinger@analog.com> Signed-off-by: Bryan Wu <bryan.wu@analog.com>
2007-06-11Blackfin arch: all symbols were offset by 4k, since we didn't have the __text label.Robin Getz1-0/+1

2007-05-19all-archs: consolidate .data section definition in asm-genericSam Ravnborg1-1/+1
With this consolidation we can now modify the .data section definition in one spot for all archs. Signed-off-by: Sam Ravnborg <sam@ravnborg.org>
2007-05-19all-archs: consolidate .text section definition in asm-genericSam Ravnborg1-1/+1

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>
