21 * Memory layout for where various images get loaded by boot scripts:
22 *
23 * scriptaddr can be pretty much anywhere that doesn't conflict with something
24 * else. Put it above BOOTMAPSZ to eliminate conflicts.
25 *
26 * pxefile_addr_r can be pretty much anywhere that doesn't conflict with
27 * something else. Put it above BOOTMAPSZ to eliminate conflicts.
28 *
29 * kernel_addr_r must be within the first 128M of RAM in order for the
30 * kernel's CONFIG_AUTO_ZRELADDR option to work. Since the kernel will
31 * decompress itself to 0x8000 after the start of RAM, kernel_addr_r
32 * should not overlap that area, or the kernel will have to copy itself
33 * somewhere else before decompression. Similarly, the address of any other
34 * data passed to the kernel shouldn't overlap the start of RAM. Pushing
35 * this up to 16M allows for a sizable kernel to be decompressed below the
36 * compressed load address.
37 *
38 * fdt_addr_r simply shouldn't overlap anything else. Choosing 32M allows for
39 * the compressed kernel to be up to 16M too.
40 *
41 * ramdisk_addr_r simply shouldn't overlap anything else. Choosing 33M allows
42 * for the FDT/DTB to be up to 1M, which is hopefully plenty.
