Small refactor to remove duplicate serial code

2011-10-01T19:52:48+00:00

This tidies up duplicate code, and checks that default_serial_console() does
in fact produce a device.

serial: implement common uart post test

2011-07-26T14:39:03+00:00

The current arch/driver specific UART posts basically boil down to setting
the UART to loop back mode, then reading and writing data.  If we ignore
the loop back part, the rest can be built upon the existing common serial
API.  So let's do just that.

First add a call back for serial drivers to implement loop back control.
Then write a post test that walks all of the serial drivers, puts them
into loop back mode, and verifies that reading/writing at all the diff
baud rates is OK.

If a serial driver doesn't support loop back mode (either it can't or
it hasn't done so yet), then skip it.  This should allow for people to
easily migrate to the new post test with existing serial drivers.

I haven't touched the few already existing uart post tests as I don't
the hardware or knowledge of converting them over.  So I've marked the
new test as weak which will allow the existing tests to override the
default until they are converted.

serial: drop serial_register return value

2011-07-26T14:38:01+00:00

The serial_register function never fails (always return 0), so change it
to a void function to avoid wasting overhead on it.

serial: push default_serial_console to drivers

2011-07-26T14:37:57+00:00

Rather than sticking arch/board/driver specific logic in the common
serial code, push it all out to the respective drivers.  The serial
drivers declare these funcs weak so that boards can still override
things with their own definition.

Blackfin: uart: add multiple serial support

2011-07-12T06:17:45+00:00

This brings CONFIG_SERIAL_MULTI support to the Blackfin on-chip UARTs.
Ends up adding only ~512bytes per additional UART.
