STATIC_HEAP="baseaddr1 size1 ... baseaddrN sizeN" if specified, indicates the host physical address regions [baseaddr, baseaddr + size) to be reserved as static heap. For instance, STATIC_HEAP="0x50000000 0x30000000", if specified, indicates the host memory region starting from paddr 0x50000000 with a size of 0x30000000 to be reserved as static heap.
