!!!THIS IS AN UNDOCUMENTED I2C BUS BUG, NOT A AMCC 4xx BUG!!!
This reset edge condition could possibly be present in every I2C
-controller and device available. For boards where a I2C bus reset
-function can be implemented a i2c_init_board() function should be
-provided and enabled by #define'ing CFG_I2C_INIT_BOARD in your
-board's config file. Note that this is NOT necessary when using the
-bit-banging I2C driver (common/soft_i2c.c) as this already includes
-the I2C bus reset sequence.

Many thanks to Bill Hunter for finding this serious BUG.
