I don't recall seeing a reference to this already, nor a resolution to the open question of how to enable U-Boot for different EOMA68 configurations, so I figured it may be useful to someone to review the applicability of a talk given at the recent FOSDEM:

I hope this is helpful to someone!
Happy Hacking

Devicetree overlays, with a fixed dtb specification representing the pins on EOMA68. An I2C EEPROM contains the id which allows uboot to pick the correct dtb overlay.
It was discussed years ago as dtb overlays were still in the conceptual phase. Last time I checked nobody had thought about *disconnecting* overlays. The assumption was, you plug in a braindead 96boards to a shield, boot, and under no circumtances remove the shield.
They clearly forgot that even on a beagleboard or braindeaf 96board, uswsusp can be installed.

Appreciated.
