Add an optional flash port parameter for IT87* SPI controllers in standalone programmer mode
If the parameter is set, the IT87* SPI driver will set the I/O base
port of the IT87* SPI controller interface to the port specified in the
parameter. Usage: flashrom -p it87spi=port=0x820
Corresponding to flashrom svn r646.
