"console=uart" only works with > 8250-compatible devices. But is it a design limitation or is it just that other UART drivers have to be modified to work with this option? My point is if the former, then the option should be something like "console=8250" (the right-hand side being the name of the driver involved; others may want to add support for other drivers). If the latter, then it's fine as is as other UART drivers may be wired to this code as a need arises.
