| 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. |
