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