2016-12-08	extmod/machine_spi: Provide reusable software SPI class.	Damien George
	So long as a port defines relevant mp_hal_pin_xxx functions (and delay) it can make use of this software SPI class without the need for additional code.
2016-10-21	py: Be more specific with MP_DECLARE_CONST_FUN_OBJ macros.	Damien George
	In order to have more fine-grained control over how builtin functions are constructed, the MP_DECLARE_CONST_FUN_OBJ macros are made more specific, with suffix of _0, _1, _2, _3, _VAR, _VAR_BETEEN or _KW. These names now match the MP_DEFINE_CONST_FUN_OBJ macros.
2016-10-04	extmod/machine_spi: Use delay_half, not baudrate, for internal timing.	Damien George
	The delay_half parameter must be specified by the port to set up the timing of the software SPI. This allows the port to adjust the timing value to better suit its timing characteristics, as well as provide a more accurate printing of the baudrate.
2016-10-03	extmod/machine_spi: Factor out software SPI code from esp8266 to extmod.	Damien George

2016-10-03	extmod/machine_spi: Simplify SPI xfer function to only take one buf len.	Damien George
	There is no need to take src_len and dest_len arguments. The case of reading-only with a single output byte (originally src_len=1, dest_len>1) is now handled by using the output buffer as the input buffer, and using memset to fill the output byte into this buffer. This simplifies the implementations of the spi_transfer protocol function.
2016-09-01	extmod: Add machine_spi with generic SPI C-protocol and helper methods.	Damien George
	The idea is that all ports can use these helper methods and only need to provide initialisation of the SPI bus, as well as a single transfer function. The coding pattern follows the stream protocol and helper methods.
