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
