This patch adds code to support read-only RTC support for guests run by partition mode ACRN. It supports RW for CMOS address port 0x70 and RO for CMOS data port 0x71. Reads to CMOS RAM offsets are fetched by reading CMOS h/w directly and writes to CMOS offsets are discarded. Signed-off-by: Sainath Grandhi <sainath.grandhi@intel.com>
