i2c-test

This program is I2C read/write program under 8120.

Usage:
read command: [iaccess 1 address arg1 ]
         arg1: data bytes number
write command: [iaccess 0 address arg1 arg2 arg3 ... ]
         arg1: data bytes number
         arg2 arg3 ...: data value    


Example:
Write 8120 Standard EVB serial EEPROM (I2C read address 0xa9, write 0xa8)
	#./iaccess 0 0xa8 2 0x5 0x36
    
    Means write 2 bytes to I2C bus, according to EEPROM support, 
    0x5 is offset, 0x36 is writing data.

And read back the offset 0x5 to verify:
	#./iaccess 0 0xa8 1 0x05
	#./iaccess 1 0xa9 1
	
    Means write 1 bytes to EEPROM I2C bus to notify the offset is 0x5.
    Then read back using "iaccess 1".
