I generally agree with this statement except that without this patch, 
almost ALL of Freescale's SoC that uses "fsl,gianfar-tbi" are broken, 
including the older ones. At least this patch fixes some of the device 
trees. Because I'm not working at Freescale, I have a very limited 
access to a few SoC which I could test this patch on. I think it is 
Freescale's responsibility to release a complementary patch to fix the 
rest of the SoC device trees.
