Note
PIN 130, 131, MEZZ1_L, MEZZ2_L, configures the board's local bus frequency. If a
single mezzanine is attached to the board, MEZZ1_L will be pulled down on the board.
If a second mezzanine is attached on-top to the first, MEZZ2_L will be pulled down on
the board. This may cause the clock generation logic to set the local bus frequency to
83.33 MHz if necessary.
