The Oxford Semiconductor OX820 is a ARM11MPcore based SoC sharing some features with the OX810 earlier SoC. This patch adds the core to wake up the second core. Clarifications about Copyrights dates : - hotplug.c was taken from an old versatile code by Ma Haijun and left verbatim - headsmp.S was taken from an old versatile code and adapted by Ma Haijun - platsmp.c is a mix from versatile code, Ma Haijun code and my code for DT Hence the 2002/2003 ARM Coryrights and 2013 Ma Haijun Copyrights.
