Just want to add a few more two cents here:

1. Perhaps instead of scattering the drivers, maybe their should be a
single driver/module for bcm283x. That way it's wouldn't be neccessary
to have all these crazy runtime dependencies.

I bought an ODROID awhile ago, and they put all their drivers in the
same directory.  The only problem is that they are not continuing to
maintain it for newer kernel versions.

2. The whole runtime device tree thing for a SOC doesn't make sense.  
On a PC you can have all kinds of combinations of devices that the end
user randomly connects together.  But for a SOC, the parts are
essentially all permanently connected together. So what is the purpose
of all the runtime configuration complexity?

I once looked at another attempt at runtime configuration of a SOC by
another company called Microchip.  It's called "Harmony" and everybody
thiks the whole thing is a mess.

3. If someone is implying to rollback the kernel version to an older
kernel, I'm not sure that makes sense.   Newer linux distros won't run
on older versions.  That's one of the issues I saw right away with the
ODROID device I bought.
