[DENX Support System]

Hello list,

inside the automatic U-Boot patch tracking system a new ticket
[DNX#2006090742000024] was created:

<snip>
> Hello,
> 
> Attached is a patch providing support for multiple I2C buses at the
> command level.  The second part of the patch includes an implementation
> for the MPC834x CPU and MPC8349EMDS board.

> Overview:
> 
> 1. Include new 'i2c' command (based on USB implementation) using
> CONFIG_I2C_CMD_TREE.  
> 
> 2. Allow multiple buses by defining CONFIG_I2C_MULTI_BUS.  Note that
> the commands to change bus number and speed are only available under the
> new 'i2c' command mentioned in the first bullet.
> 
> 3. The option CFG_I2C_NOPROBES has been expanded to work in multi-bus
> systems.  When CONFIG_I2C_MULTI_BUS is used, this option takes the form
> of an array of bus-device pairs.  Otherwise, it is an array of uchar. 
> 
> CHANGELOG:
>         Added new 'i2c' master command for all I2C interaction.  This is
> conditionally compiled with CONFIG_I2C_CMD_TREE.  New commands added for
> setting I2C bus speed as well as changing the active bus if the board
> has more than one (conditionally compiled with
> CONFIG_I2C_MULTI_BUS).  Updated NOPROBE logic to handle multiple buses.
> Updated README.

> regards,
