I'm not sure what you're trying to achieve - initrd like desktop 
systems, or something else?

I haven't had a need to use initrd on the MicroBlaze, so can't give you 
the step-by-step.  It will be just like any other Linux system.  Lots of 
docs out there on initrd - this one's probably a reasonable starting point:
