Nice series!

Just note that there is one possible problem with COMPILE_TEST
when the platforms are enabled, as you can then disable a driver
that is normally there, and that can in turn cause problems in
rare cases, e.g. when the driver has a global function that is
called from platform code. I don't know if any of the drivers
do that, but if they do, you'd have to use

config RESET_ATH79
       bool "AR71xx Reset Driver" if COMPILE_TEST && !ATH79
       default ATH79

to ensure that it's impossible to disable the driver on platforms
that require it.
