	I2C protocol implementation.

	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:
.

.		      | VPD EEPROM |

.			| Temperature and |
.			| Voltage Sensor  |
.			| 	LM80	  |

. | _CTRL  |	| _DATA  |	|   _SW    |
. +--------+	+--------+	+----------+
.
	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.
