-- Legacy I2C Support:  CONFIG_HARD_I2C
-
-               NOTE: It is intended to move drivers to CONFIG_SYS_I2C which

-
-               - more than one i2c adapter is usable
-               - approved multibus support
-               - better i2c mux support
-
-               ** Please consider updating your I2C driver now. **
-
-               These enable legacy I2C serial bus commands. Defining
-               CONFIG_HARD_I2C will include the appropriate I2C driver
-               for the selected CPU.
-
-               This will allow you to use i2c commands at the u-boot
-               command line (as long as you set CONFIG_CMD_I2C in
-               CONFIG_COMMANDS) and communicate with i2c based realtime
-               clock chips. See common/cmd_i2c.c for a description of the
-               command line interface.
-
-               CONFIG_HARD_I2C selects a hardware I2C controller.
-
-               There are several other quantities that must also be
-               defined when you define CONFIG_HARD_I2C.
-
-               In both cases you will need to define CONFIG_SYS_I2C_SPEED
-               to be the frequency (in Hz) at which you wish your i2c bus
-               to run and CONFIG_SYS_I2C_SLAVE to be the address of this node (ie
-               the CPU's i2c node address).
-
-               Now, the u-boot i2c code for the mpc8xx
-               (arch/powerpc/cpu/mpc8xx/i2c.c) sets the CPU up as a master node
-               and so its address should therefore be cleared to 0 (See,
