Risking my limbs here by breaking in this late in the discussion... (I 
wasn't able to reply earlier) but where does it state it needs to be 
uppercase? I found a bunch of microblaze code which seems to use the 
lowercase xlnx and freescale seems happy with fsl. Unless I'm missing 
something obvious here I guess ALTR would actually be the first to use 
uppercase.
The only reference to uppercase I found in the ePAPR docs was chapter 
1.6 that talks about uppercase hex-characters as an OUI.
Not that I terribly mind either way, but I want to double-check before 
we go ahead and change all altera-related devicetree stuff to uppercase.
