26 * Memory layout for where various images get loaded by boot scripts:
27 *
28 * scriptaddr can be pretty much anywhere that doesn't conflict with something
29 * else. Put it above BOOTMAPSZ to eliminate conflicts.
30 *
31 * pxefile_addr_r can be pretty much anywhere that doesn't conflict with
32 * something else. Put it above BOOTMAPSZ to eliminate conflicts.
33 *
34 * kernel_addr_r must be within the first 128M of RAM in order for the
35 * kernel's CONFIG_AUTO_ZRELADDR option to work. Since the kernel will
36 * decompress itself to 0x8000 after the start of RAM, kernel_addr_r
37 * should not overlap that area, or the kernel will have to copy itself
38 * somewhere else before decompression. Similarly, the address of any other
39 * data passed to the kernel shouldn't overlap the start of RAM. Pushing
40 * this up to 16M allows for a sizable kernel to be decompressed below the
41 * compressed load address.
42 *
43 * fdt_addr_r simply shouldn't overlap anything else. Choosing 32M allows for
44 * the compressed kernel to be up to 16M too.
45 *
46 * ramdisk_addr_r simply shouldn't overlap anything else. Choosing 33M allows
47 * for the FDT/DTB to be up to 1M, which is hopefully plenty.
