This patch adds the basic part of Goya's H/W initialization. It adds code that initializes Goya's internal CPU, various registers that are related to internal routing, scrambling, workarounds for H/W bugs, etc. It also initializes Goya's security scheme that prevents the user from abusing Goya to steal data from the host, crash the host, change Goya's F/W, etc. Reviewed-by: Mike Rapoport <rppt@linux.ibm.com> Signed-off-by: Oded Gabbay <oded.gabbay@gmail.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
