There's actually a relative lot of vendor stuff that's based on "only" 2 or so year old U-Boot, and starts to get things right. So yes, once you start to factor in the design->production lag, we will start to see more and more devices that come out with these features enabled and either in-use (because it's relevant to the product) or community-used (because the product can be end-user-used and it's not something that was turned off). And we're starting to see more and wider silicon vendor support coming in and in my experience there's often a lot of "if the vendor defaults work, just add what we need on top" in custom designs. For the kernel and U-Boot both. -- Tom
