Yes, it worked! I just uploaded my fixed version with some extra details and 
other fixes.

No problem! This was a consequence of the L4 work plus a perusal of the 
headers from U-Boot, which might be helpful when I have to configure some

I hope to write some other L4Re drivers, and there will be some more 
documentation of the hardware written as things hopefully progress.
