I2C
=================
The i2c utilities have been tested on both Rev B. and Rev C. and
-look good. The iprobe command implementation has been updated to
+look good. The 'i2c probe' command implementation has been updated to
allow for 'skipped' addresses. Some i2c slaves are write only and
cause problems when a probe (read) is performed (for example the
CDCV850 clock controller at address 0x69 on the ebony board).
CONFIG_SYS_I2C_NOPROBES macro in your board-specific header file. When
defined, all specified addresses are skipped during a probe.
The addresses that are skipped will be displayed in the output

For example, to prevent probing address 0x69, define the macro as
