DO NOT USE these pins for anything other
than attaching an I2C ID EEPROM. Leave
unconnected if ID EEPROM not required.
(GPIO_GEN1)
These pins are reserved for HAT ID EEPROM.
(SPI_CE0_N)

(SPI_MISO)
(GPIO_GEN2)
(GPIO_GEN6)
At boot time this I2C interface will be
interrogated to look for an EEPROM
that identifes the attached board and
allows automagic setup of the GPIOs
(and optionally, Linux drivers).
