Hm.. I've seen an extreme case where there's around 100MB of a 128MB DDR part dedicated to non-Linux firmware. So attempting to load that firmware into DDR just doesn't work at all unless you have this patch series. This is the most extreme case I've seen though. Please also note that this is also about skipping the memcpy() step, which I should probably quantify how much that actually matters if at all. I'll make sure to do some loading time measurements in the next round.
