They gave us the same patch. I was hoping their SoC team would get it 
into mv-ddr-marvell (or even their vendor USP) but obviously they're 
still sitting on it. I know it improved matters for some of our boards 
but it didn't totally fix them we still had yield problems when we 
ramped up production.
