If you use barebox as first-stage BL, then you definitely need the 
pinmuxing. If you use it as second-stage BL, u-boot should have set
it up already. The log above suggests that you already used the same
egiga/mvneta controller before on u-boot so that should be fine.

Currently, I cannot tell what is the problem here. I never tried 2nd
stage booting. Can you add the pinmuxing and try uart booting? Also,
can you connect the RN104 directly to a PC and run wireshark on the
interface? You should see packets from the MAC above when e.g. ping
from RN104.
