There are 2 reasons why SOS ve820 has to be separated from host e820: - in hybrid mode, SOS may not own all the host memory. - when SOS is being re-launched, it needs an untainted version of host e820 to create SOS ve820. This patch creates sos_e820 table for SOS and keeps host e820 intact during SOS creation. Tracked-On: #2700 Signed-off-by: Zide Chen <zide.chen@intel.com> Acked-by: Eddie Dong <eddie.dong@intel.com>
