| 3 | help | |
| 4 | Mailbox is a framework to control hardware communication between | |
| 5 | on-chip processors through queued messages and interrupt driven | |
| 6 | signals. Say Y if your platform supports hardware mailboxes. | |

| 13 | help | |
| 14 | Say Y here if you want to build the ARM MHU controller driver. | |
| 15 | The controller has 3 mailbox channels, the last of which can be | |
| 16 | used in Secure mode only. | |

| 21 | help | |
| 22 | An implementation of the ARM PL320 Interprocessor Communication | |
| 23 | Mailbox (IPCM), tailored for the Calxeda Highbank. It is used to | |
| 24 | send short messages between Highbank's A9 cores and the EnergyCore | |
| 25 | Management Engine, primarily for cpufreq. Say Y here if you want | |
| 26 | to use the PL320 IPCM support. | |

| 47 | bool "Platform Communication Channel Driver" | |
| 48 | depends on ACPI | |
| 49 | help | |
| 50 | ACPI 5.0+ spec defines a generic mode of communication | |
| 51 | between the OS and a platform such as the BMC. This medium | |
| 52 | (PCC) is typically used by CPPC (ACPI CPU Performance management), | |
| 53 | RAS (ACPI reliability protocol) and MPST (ACPI Memory power | |
| 54 | states). Select this driver if your platform implements the | |
| 55 | PCC clients mentioned above. | |
