It relates to the SMC which parameter RAM  location  is  in  conflict
with the SPI/I2C parameter RAM, i. e. SMC1.

I think it makes little sense to speculate about this without knowing
anything about how the microcode patch actually works.

No, this is impossible as there is no SCC4 on a MPC823/850.

It is not even mentioned, so assume it is NOT supported.

I think it's a new feature. Don't tell anyone it was an accident. :-)
