    What really needs to be done is to create some kind of mini-driver
architecture for the boot and debug serial drivers.
    There are only something like 4 or 5 simple functions, and in many
cases only putchar() needs implimented.
   
    The whole boot/debug early serial stuff is highly and unescesarily
8250 specific. While there are several alternatives,
    these typically involve numerous #ifdef's and then end up being
board specific.
   
    Being able to output data, before linux has loaded, or before the
standard serial drivers have initialized is probably not important for
    working systems, but is incredibly useful when trying to bring up a
new board - particularly if you are trying to do so with
    silly scopes, logic analyzers, and other electronic gizmo's
