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