| bool "Enable RapidIO Input/Output Ports" |
| depends on RAPIDIO |
| help |
| The RapidIO specification describes a Output port transmit |
| enable and a Input port receive enable. The recommended state |
| for Input ports and Output ports should be disabled. When |
| this switch is set the RapidIO subsystem will enable all |
| ports for Input/Output direction to allow other traffic |
| than Maintenance transfers. |

| select DMADEVICES |
| select DMA_ENGINE |
| help |
| Say Y here if you want to use DMA Engine frameork for RapidIO data |
| transfers to/from target RIO devices. RapidIO uses NREAD and |
| NWRITE (NWRITE_R, SWRITE) requests to transfer data between local |
| memory and memory on remote target device. You need a DMA controller |
| capable to perform data transfers to/from RapidIO. |

| If you are unsure about this, say Y here. |

| help |
| Say Y here if you want the RapidIO subsystem to produce a bunch of |
| debug messages to the system log. Select this if you are having a |
| problem with the RapidIO subsystem and want to see more of what is |
| going on. |

| There are different enumeration and discovery mechanisms offered |
| for RapidIO subsystem. You may select single built-in method or |
| or any number of methods to be built as modules. |
| Selecting a built-in method disables use of loadable methods. |
