| 58 | * kernel_addr_r must be within the first 128M of RAM in order for the |

| 60 | * decompress itself to 0x8000 after the start of RAM, kernel_addr_r |
| 61 | * should not overlap that area, or the kernel will have to copy itself |
| 62 | * somewhere else before decompression. Similarly, the address of any other |
| 63 | * data passed to the kernel shouldn't overlap the start of RAM. Pushing |
| 64 | * this up to 16M allows for a sizable kernel to be decompressed below the |
| 65 | * compressed load address. |

| 67 | * fdt_addr_r simply shouldn't overlap anything else. Choosing 32M allows for |

| 70 | * ramdisk_addr_r simply shouldn't overlap anything else. Choosing 33M allows |
