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