This patch series adds support for the Synopsys DesignWare ARC700 architecture.
DesignWare ARC700 is family of 32-bit CPUs developed by Synopsys, Inc. Since version 3.9 ARC architecture is supported in mainline Linux developemnt. And now to get better support in commonly used boot-loader we are introducing port of U-Boot for ARC700 CPUs. Patches included in this series are also available on GitHub in the 'for-upstream-v3' branch: g...@github.com:foss-for-synopsys-dwc-arc-processors/u-boot.git Also browsable here: https://github.com/foss-for-synopsys-dwc-arc-processors/u-boot/tree/for-upstream-v3 NOTE: there's an acked by Tom Rini prerequisite for Arcangel4 board: http://patchwork.ozlabs.org/patch/300901/ For those who are interested in building this port please download pre-built toolchains for x86_64 hosts. For RedHat-based distros: https://github.com/foss-for-synopsys-dwc-arc-processors/toolchain/releases/download/arc-4.8-R2/arc_gnu_4.8-R2_prebuilt_uclibc_le_rhel6_install.tar.gz For Debian-based distros: https://github.com/foss-for-synopsys-dwc-arc-processors/toolchain/releases/download/arc-4.8-R2/arc_gnu_4.8-R2_prebuilt_uclibc_le_ubuntu_install.tar.gz Major changes for v3: * Clean-up of headers copied from Linux kernel and other architectures. * Fix checkpatch.pl errors and most of warnings (except really required "typedefs" in "posix_types.h" and "volatile" in data accessors implemented with assembly instuctions). * Arcangel4 board now has big-endian modificatoin so both endianesses could be used for testing and debugging. * Common board init functionality moved from boards to cpu sources. Each patch that follows has detailed description of its changes.
