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.

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).
