There are'nt 10 serial ports exposed in j782s2. ok - lets say we do this, then: [1] is needed to boot? but why do we need to do that for all armv8 platforms when aliases allows us to trim it to just the 3 or 4 serial ports the platform really needs That + being able to use the convention that serial2 is always linux console, is'nt that a good thing? Hence recommending to just expose the serialports as aliases to exactly what we need while keeping serial2 as the linux console (which in this case happens to be main_uart8 - example as j721s2 does).
