Full logic to supprot vRPMB: 1. Automatic switch between physical or simulated RPMB. But hardcode to use simulated one. 2. Parse RPMB cmd to basic APIs to: 2.1 check request frame HMAC with uos vkey 2.2 replace RPMB frame with real values. 3. RPMB partitioning for multiple UOS. It's hardcoded for coming config file support. Signed-off-by: Huang Yang <yang.huang@intel.com> Signed-off-by: Du Min <minx.du@intel.com> Acked-by: Zhu Bing <bing.zhu@intel.com>
