+
+	General Description:
+
+	The I2C protocol is used for the temperature sensors and for
+	the serial EEPROM which hold the configuration.
+
+	This file covers functions that allow to read write and do
+	some bulk requests a specified I2C address.
+
+	The Genesis has 2 I2C buses. One for the EEPROM which holds
+	the VPD Data and one for temperature and voltage sensor.
+	The following picture shows the I2C buses, I2C devices and
+	their control registers.
+
+	Note: The VPD functions are in skvpd.c
+.
+.	PCI Config I2C Bus for VPD Data:

+. +--------+	+--------+	+----------+
+.
+	The I2C bus may be driven by the B2_I2C_SW or by the B2_I2C_CTRL
+	and B2_I2C_DATA registers.
+	For driver software it is recommended to use the I2C control and
+	data register, because I2C bus timing is done by the ASIC and
+	an interrupt may be received when the I2C request is completed.
+
+	Clock Rate Timing:			MIN	MAX	generated by
+		VPD EEPROM:			50 kHz	100 kHz		HW
+		LM80 over I2C Ctrl/Data reg.	50 kHz	100 kHz		HW
+		LM80 over B2_I2C_SW register	0	400 kHz		SW
+
+	Note:	The clock generated by the hardware is dependend on the
+		PCI clock. If the PCI bus clock is 33 MHz, the I2C/VPD
+		clock is 50 kHz.
