That looks very interesting indeed.

my hardware has only I2C connected to the MachXO2 (hence the patch
series...), so I cannot test your patches directly. 

Since adding I2C requires some quirks with respect to the programming
commands (some are differ to the SPI ones, ...) it will take me some
time to add my patches on top of yours in order to test, but after
having had a short glance at your patch series, I think it should be
feasible.

Though, I think you should allow the program-gpios, init-gpios and
done-gpios for machxo2 and have them as optional, at least for machxo2.

Best regards
Johannes
