Hi, Johannes!

I just came across your patches. Surprisingly, our work interferes.

I recently posted patch-series for configuring ECP5 and was asked to make
generalized sysCONFIG driver with support for both ECP5 and MachXO2, which
I did. Sadly I don't have hardware with MachXO2, but you clearly do :)

Please, take a look at

and please help test MachXO2 variant. When we pull this off, you may add I2C
interface on top.
