Given that UEFI is switching and the requirement for soldering to get to the on board UART it does seem to make sense, though it will create some pain for current users. > > While we're at it there was a recent talk which mentioned a fairly large > > amount of functionality that's apparently already "upstream" for this > > device but not included in the DT, assuming that means that driver > > support is there it would be good to add the corresponding DT. > Indeed, I think this comment is targeted to toward the d410c though as > there are drivers for eMMC, and microsd drivers upstream but no DT > bindings. I do not believe currently this is the case for HiKey. My understanding is that it applies to both with slightly different driver sets, the slides aren't online yet (!) but if you look at 10:52 or so in the video we should have SD/eMMC on HiKey in v4.1 with thermal and CPUfreq added in v4.2. It also looks like there's just some DT additions needed to enable reset, cpuidle and CPU hotplug using generic code (mainly the constants for PSCI I expect).
