 lennart: you've fundamentally misinformed of the reality of the ARM
hardware development world.  there are over 600 ARM licensees,
world-wide.   automatically therefore you're above the threshold
number that you arbitrarily picked.

 additionally, each hardware device that uses any one of the products
created by any one of those 600+ licensees *will*, by the very nature
of that hardware design having hard-wired interfaces, be completely
and utterly different from any other device.  GPIO20 for example could
be used to power on a WIFI module on one device, and could be
disconnected or used via a multiplex option as an SD card's clock

 if you look at the xanadux source code (on sourceforge) when i was
working on the reverse-engineering of HTC wince phones, we had *OVER
250* source code files added which covered i believe it was 9 new
hardware platforms for the PXA25x and PXA27x series [before marvell
bought the intel pxa architecture]

 russell bless him asked us to flatten these out to a single
directory.  the number of files to be added was *double* that of the
total existing number of files that had ever been contributed up until
that point.

 even with 5 of us working and coordinating closely for about eighteen
months on those 9 products, it was virtually impossible for us to
generate any kind of significantly common code.

 all that devicetree has done is move the problem, as well as add a
runtime overhead to the execution of resource-critical devices.

 not very clever, that.
