Currently implemented only for LPC1768. On this platform, when hardware
flow control is not directly supported, it will be emulated.
Also added "not_implemented.c" as a placeholder for various HAL functions
that might not be implemented on all platforms (in this particular case,
serial_set_flow_control). These are weak implementations that default to a
"not implemented" error message.
These were done to silence GCC warnings and fix potential bugs where
they would never be equal when the enumeration wasn't a 32-bit type.
For example, common/pinmap_common.c used to contain this code:
if (pin == (uint32_t)NC)
I switched it to:
if (pin == (PinName)NC)
I wonder why this casting to uint32_t was done in the first place?
Maybe another supported compiler requires it?
