* [Blackfin] serial driver: Fix bug Poll RTS/CTS status in DMA mode as wellSonic Zhang2008-02-02

* [Blackfin] serial driver: fix bug - cache the bits of the LSR on systems ↵Mike Frysinger2007-12-24
| | | | | | | | | | | | | | | where the LSR is read-to-clear Cache the bits of the LSR on systems where the LSR is read-to-clear so that we can safely read the LSR in random places. this fixes older parts where break/framing/parity/overflow was not being detected at all in PIO mode, and this fixes newer parts where break/framing/parity/overflow was being reported all the time without being cleared.

* [Blackfin] arch: Fix gpio label handlingMichael Hennerich2007-12-24
| | | | | | | | | | | | | early serial init also utilizes the peripheral request api - however at this point bfin_gpio_init didn't allocate memory for the labels. So we always have two zombies (allocated pin functions without labels) This happens before the initcalls - We now allocate memory statically. Define MAX_RESOURCES individually for each cpu.

* Blackfin arch: initial supporting for BF548-EZKITRoy Huang2007-07-12
| | | | | | | | | | | | | | | | | The ADSP-BF54x was specifically designed to meet the needs of convergent multimedia applications where system performance and cost are essential ingredients. The integration of multimedia, human interface, and connectivity peripherals combined with increased system bandwidth and on-chip memory provides customers a platform to design the most demanding applications. Since now, ADSP-BF54x will be supported in the Linux kernel and bunch of related drivers such as USB OTG, ATAPI, NAND flash controller, LCD framebuffer, sound, touch screen will be submitted later.

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>
