The previous would reserve memory for trusty in SOS kernel. Howerer, there would no available 16 MB continue memory any more after a long time. This result in allocating memory for trusty failed. This patch will reserve memory for trusty in ACRN hypervisor in which case the memory allocation for trusty will never fail. Tracked-On: #1942 Signed-off-by: Li, Fei1 <fei1.li@intel.com>
