42 *
43 * scriptaddr can be pretty much anywhere that doesn't conflict with something
44 * else. Put it above BOOTMAPSZ to eliminate conflicts.
45 *
46 * pxefile_addr_r can be pretty much anywhere that doesn't conflict with
47 * something else. Put it above BOOTMAPSZ to eliminate conflicts.
48 *
49 * kernel_addr_r must be within the first 128M of RAM in order for the
50 * kernel's CONFIG_AUTO_ZRELADDR option to work. Since the kernel will
51 * decompress itself to 0x8000 after the start of RAM, kernel_addr_r
52 * should not overlap that area, or the kernel will have to copy itself
53 * somewhere else before decompression. Similarly, the address of any other
54 * data passed to the kernel shouldn't overlap the start of RAM. Pushing
55 * this up to 16M allows for a sizable kernel to be decompressed below the
56 * compressed load address.
57 *
58 * fdt_addr_r simply shouldn't overlap anything else. Choosing 32M allows for
59 * the compressed kernel to be up to 16M too.
60 *
61 * ramdisk_addr_r simply shouldn't overlap anything else. Choosing 33M allows
62 * for the FDT/DTB to be up to 1M, which is hopefully plenty.
