| 32 | * Memory layout for where various images get loaded by boot scripts: | |
| 33 | * | |
| 34 | * scriptaddr can be pretty much anywhere that doesn't conflict with something | |
| 35 | * else. Put it above BOOTMAPSZ to eliminate conflicts. | |
| 36 | * | |

| 40 | * kernel_addr_r must be within the first 128M of RAM in order for the | |
| 41 | * kernel's CONFIG_AUTO_ZRELADDR option to work. Since the kernel will | |
| 42 | * decompress itself to 0x8000 after the start of RAM, kernel_addr_r | |
| 43 | * should not overlap that area, or the kernel will have to copy itself | |
| 44 | * somewhere else before decompression. Similarly, the address of any other | |
| 45 | * data passed to the kernel shouldn't overlap the start of RAM. Pushing | |
| 46 | * this up to 16M allows for a sizable kernel to be decompressed below the | |
| 47 | * compressed load address. | |
| 48 | * | |
| 49 | * fdt_addr_r simply shouldn't overlap anything else. Choosing 32M allows for | |
| 50 | * the compressed kernel to be up to 16M too. | |
| 51 | * | |
| 52 | * ramdisk_addr_r simply shouldn't overlap anything else. Choosing 33M allows | |
| 53 | * for the FDT/DTB to be up to 1M, which is hopefully plenty. | |
