| 7 | Enable support for the mailbox driver class. Mailboxes provide the |
| 8 | ability to transfer small messages and/or notifications from one |
| 9 | CPU to another CPU, or sometimes to dedicated HW modules. They form |
| 10 | the basis of a variety of inter-process/inter-CPU communication |
| 11 | protocols. |

| 18 | Enable support for the mailboxes that provide a comminucation |
| 19 | channel with Apple IOP controllers integrated on Apple SoCs. |
| 20 | These IOP controllers are used to implement various functions |
| 21 | such as the System Management Controller (SMC) and NVMe and this |
| 22 | driver is required to get that functionality up and running. |
