This patch series adds support for the OpenRISC 1000 architecture.
The OpenRISC architecture has been around for about a decade and has experienced a revival in the last couple of years from the efforts of a small, but dedicated community compound of both commercial and independent contributors.
Most of the development takes place on opencores.org/or1k and openrisc.net.
The patches included in this series are also available in the 'for-upstream' branch in the following git repository:
git://openrisc.net/stefan/u-boot
which is also browsable here:
http://git.openrisc.net/cgit.cgi/stefan/u-boot/?h=for-upstream
NOTE: The openrisc-generic board depends on this pending patch to build properly: net/ethoc: use flush_dcache_range instead of flush_dcache (http://patchwork.ozlabs.org/patch/123622/)
