[U-Boot] [PATCH v4 0/9] Add support for the ARC700 architecture

[Alexey Brodkin]

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 at github.com:foss-for-synopsys-dwc-arc-processors/u-boot.git

Also browsable here:

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

For those who are interested in building this port please download pre-built
toolchains for x86_64 hosts.

Major changes for v4:

 * Clean-up of board configurations.
