Hi Stephen,

Perhaps I can make the point another way. Assuming that the SOC in question is ARM-based and has Linux support it either supports FDT now or presumably will fairly soon.
Sure, but I'm *explicitly* avoiding relying on DT for this, because there are plenty of things that happen before DT can or should be touched that might warrant serial port output.
Also totally true and valid. But what I'd like to see is: parse_odmdata(void *ptr) { if (ptr->console) device_tree_register_uart(... fake it ...); }
In other words, if we add the register a port call now, there's a history of adding just one more thing, by someone else (say am335x and our EVMs that differ on where primary UART is, and only need a little different logic to say 'oh! this one.') and making a mess of things. Once we deal with device trees in some manner, then we can just fake their existence at this point and pass in the console information from ODMDATA.
