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.
