Hm, you're right. Not sure, I wouldn't increase the CMA buffer more as 
needed though, as any unused CMA space is basically wasted, it can't be 
used for caches etc right now.

But I can increase it to 64 MB to not divert from armv7 if that's 
preferred. As all layerscape boards usually come with a large amount of 
RAM, I assume?
