| 14 | ----------- |
| 15 | |
| 16 | The addrmap command is used to display non-identity virtual-physical memory |
| 17 | mappings for 32-bit CPUs. |
| 18 | |
| 19 | The output may look like: |
| 20 | |
| 21 | :: |
| 22 | |
| 23 | => addrmap |
| 24 | vaddr paddr size |

| 33 | The first column indicates the virtual address. |
| 34 | The second column indicates the physical address. |
| 35 | The third column indicates the mapped size. |
