| * scriptaddr can be pretty much anywhere that doesn't conflict with something |
| * else. Put it above BOOTMAPSZ to eliminate conflicts. |

| * kernel_addr_r must be within the first 128M of RAM in order for the |
| * kernel's CONFIG_AUTO_ZRELADDR option to work. Since the kernel will |
| * decompress itself to 0x8000 after the start of RAM, kernel_addr_r |
| * should not overlap that area, or the kernel will have to copy itself |
| * somewhere else before decompression. Similarly, the address of any other |
| * data passed to the kernel shouldn't overlap the start of RAM. Pushing |
| * this up to 16M allows for a sizable kernel to be decompressed below the |
| * compressed load address. |
| * |
| * fdt_addr_r simply shouldn't overlap anything else. Choosing 32M allows for |
| * the compressed kernel to be up to 16M too. |
| * |
| * ramdisk_addr_r simply shouldn't overlap anything else. Choosing 33M allows |
| * for the FDT/DTB to be up to 1M, which is hopefully plenty. |
