149 | * Memory layout for where various images get loaded by boot scripts: | |

157 | * kernel_addr_r must be within the first 128M of RAM in order for the |
158 | * kernel's CONFIG_AUTO_ZRELADDR option to work. Since the kernel will | |
159 | * decompress itself to 0x8000 after the start of RAM, kernel_addr_r | |
160 | * should not overlap that area, or the kernel will have to copy itself | |
161 | * somewhere else before decompression. Similarly, the address of any other | |
162 | * data passed to the kernel shouldn't overlap the start of RAM. Pushing | |
163 | * this up to 16M allows for a sizable kernel to be decompressed below the | |
164 | * compressed load address. | |
165 | * | |
166 | * fdt_addr_r simply shouldn't overlap anything else. Choosing 32M allows for | |
167 | * the compressed kernel to be up to 16M too. | |
168 | * | |
169 | * ramdisk_addr_r simply shouldn't overlap anything else. Choosing 33M allows | |
170 | * for the FDT/DTB to be up to 1M, which is hopefully plenty. | |
