[ Upstream commit d2b8610024 ]
Enabling a whole subsystem from a single driver 'select' is frowned
upon and won't be accepted in new drivers, that need to use 'depends on'
instead. Existing selection of DMAENGINES will then cause circular
dependencies. Replace them with a dependency.

---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.

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.

There are different enumeration and discovery mechanisms offered

Selecting a built-in method disables use of loadable methods.
