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-v4' branch:
git@github.com:foss-for-synopsys-dwc-arc-processors/u-boot.git

NOTE: there's an acked by Tom Rini prerequisite for Arcangel4 board:
