| 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 16M allows for a sizable kernel to be decompressed below the |
| 40 | * compressed load address. |
| 41 | * |
| 42 | * fdt_addr_r simply shouldn't overlap anything else. Choosing 32M allows for |
