Instead of attempting (and failing) to achieve universal support I would 
rather see a framework that could easily be configured with the 
appropriate SIO support and allow for board specific configuration if 
necessary. This should remove a lot of the complexity that gives very 
little advantage in trying for universal support. coreboot is built as 
hardware specific and I see no reason why the panic room support should 
not be the same. Choosing the SIO support to configure for the panic 
room can be easily done from the output of superiotool.
Additionally if it was done in such a way that the serial transport 
could be easily replaced by USB debug instead then we could really have 
something that would be useful for new boards.
