But, how about userspace
needing to know which SoC they are on, without needing to depend on
board->soc mapping? How do we help resolve that?

Why the user space should care about exact SOC ?

examples vary - trivial one is: debug tools like omapconf[1] or testing
tools like opentest[2] need some standard way to ensure Linux kernel is
functional - trusting the least set of parameters is usually what we
would prefer. while building a generic distro such as debian or yocto,
one prefers NOT to need to do a package build per SoC/perboard - that
never scales. instead, you'd like the same application run on different
systems dynamically.

I guessed omapconf example is coming though Keystone has no such tool
yet ;-). Opentest shouldn't need that info either.

I do agree that having a soc along with board is useful in
longer run to accommodation more boards and variants.
And only on that merit, I am willing to take these patches.

Please refresh the series commit messages based on the
