+                When a board is reset during an i2c bus transfer
+                chips might think that the current transfer is still
+                in progress. On some boards it is possible to access
+                the i2c SCLK line directly, either by using the
+                processor pin as a GPIO or by having a second pin
+                connected to the bus. If this option is defined a
+                custom i2c_init_board() routine in boards/xxx/board.c
+                is run early in the boot sequence.
