37 | * property contents. The dt strings contain a separate block with just | ||
38 | * the strings for the property names, and is fully page aligned and | ||
39 | * self contained in a page, so that it can be kept around by the kernel, | ||
40 | * each property name appears only once in this page (cheap compression) | ||

42 | * the mem_rsvmap contains a map of reserved ranges of physical memory, | ||
43 | * passing it here instead of in the device-tree itself greatly simplifies | ||
44 | * the job of everybody. It's just a list of u64 pairs (base/size) that | ||
45 | * ends when size is 0 | ||
