What do you see in the:

Device Drivers --->
<*> Userspace I/O drivers --->

?

Assuming that the SDK was not installed properly the latest SDK version can be downloaded from:

Linux® SDK for QorIQ® Processors | NXP 

Detailed description of the RMU testing on P4080DS is provided in the SDK Documentation:

USDPAA RMU User Manual

Microcode is required for FMan, but FMan operation is not connected with RapidIO.
