 it is slightly more complex (3 that is) because a library and
associated linux kernel device-driver has to also be written that
reads from the I2C EEPROM (to be added to both u-boot and the linux
kernel), in order to use the devicetree fragment merging... overlay!
that's what it's called.

 it is *not* going to be okay to just blop in one devicetree file for
eoma68-a20-with-microdesktop, one devicetree file for
eoma68-rk3288-with-microdesktop, one devicetree file for
eoma68-a20-with-laptop-housing, one devicetree file for
eoma68-rk3288-with-laptop-housing etc. etc.

 preventing that kind of insane O(N * M) devicetree proliferation and
reducing it down to O(N + M)  *IS* the entire point of the EOMA68
