Laurent MEUNIER f77ecf4e12 STM32: Put some serial code in common between families 2017-06-09 13:30:54 +02:00
Laurent MEUNIER c5c33f1d0f STM32: serial: clear Overrun flag if it is set when checking if readable 
Note that this could have side effects on the application as it would
not be aware that data has been missed. This may be later solved by
adding an error management parameter to the Serial API in mbed.

The advantage is that the serial link can work again.

Francisco J. Manno 5e98da14d3 STM32s Serial does not properly handle parity bits 
Reworked the serial_format() function for STM32F0x
devices to take the format in the form:
data_bits - parity - stop_bits

E.g. 8 - N - 1

where data_bits exclude the parity bit.
Added a case for 7 bits data as at least the chips
STM32F0x1/STM32F0x2/STM32F0x8 support 7 bits data.

Consolidated serial_format() and uart_init()
functions into a general TARGET_STM serial_api.c
file since the functions are common to all STM targets.

Fixes #4189
