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