[PATCH 0/4] serial: 8250 driver improvements & Cavium OCTEON serialsupport

[David Daney]

This is a follow up to the 'Allow for replaceable I/O functions in
8250 driver' patch I sent yesterday.  I hope it addresses the issues
raised by Alan Cox and Arnd Bergmann.

The four parts of the patch are as follows:

1/4) Add replaceable I/O functions to the 8250 driver.  This allows
    platform specific register access code to be moved out of the
    driver into the platform support files.

2/4) Add a new port flag UPF_FIXED_TYPE that allows callers of
    serial8250_register_port() to specify the port type and disables
    probing.

3/4) Add a 'bugs' field to the serial8250_config.  Used in conjunction
    with 2/4, this allows the bugs flags to be set without probing.

4/4) Add an entry to uart_config for PORT_OCTEON describing the
    OCTEON's internal UARTs.  Two new bug flags are defined to
    account for PORT_OCTEON's peculiarities.

Comments welcome,

David Daney
