Linux has been ported to HS38x series, a 10 stage pipeline core which supports MMU (with huge pages) and SMP (upto 4 cores) among other features. - www.synopsys.com/dw/ipdir.php?ds=arc-hs38-processor - http://news.synopsys.com/2014-10-14-New-DesignWare-ARC-HS38-Processor-Doubles-Performance-for-Embedded-Linux-Applications - http://www.embedded.com/electronics-news/4435975/Synopsys-ARC-HS38-core-gives-2X-boost-to-Linux-based-apps This sub-series introduces changes to existing in-tree port of ARC700 core (based on ARCompact ISA) to allow for better code sharing with new ARCv2 code. The actual ARCv2 port will follow as a seperate series. Please review !
