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 our development takes place on opencores.org/or1k and openrisc.net. Porting U-Boot for OpenRISC is a part of this revival, and we have now reached a point where we feel that our code is ready to be considered for inclusion in mainline. We have tried to keep the code in line with what is our understanding of the philosophy and style of U-Boot. Please take time to review our code and point out for us where we still might have failed. The patches included in this series are also availabe 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/) This however should not need to delay the review of our code.
