45 * This is what gets passed to the kernel by prom_init or kexec
46 *
47 * The dt struct contains the device tree structure, full pathes and
48 * property contents. The dt strings contain a separate block with just
49 * the strings for the property names, and is fully page aligned and
50 * self contained in a page, so that it can be kept around by the kernel,
51 * each property name appears only once in this page (cheap compression)
52 *
53 * the mem_rsvmap contains a map of reserved ranges of physical memory,
54 * passing it here instead of in the device-tree itself greatly simplifies
55 * the job of everybody. It's just a list of u64 pairs (base/size) that
56 * ends when size is 0
