DBAU1550. This is parameterized somewhat as machdep pluggable code, so different boards can supply different implementations. At the moment, the DBAU1550 is the only Au1550 board I know of with SPI connected devices. I have not enabled I2C on the DBAU1550, as we do not have drivers for either of the I2C connected devices (a different temperature/voltage sensor and a serial eeprom.)
