+         Enable I2C support for sandbox. This is an emulation of a real I2C
+         bus. Devices can be attached to the bus using the device tree
+         which specifies the driver to use. As an example, see this device
+         tree fragment from sandbox.dts. It shows that the I2C bus has a
+         single EEPROM at address 0x2c (7-bit address) which is emulated by
+         the driver for "sandbox,i2c-eeprom", which is in
+         drivers/misc/i2c_eeprom_emul.c.
