Hello list,

inside the automatic U-Boot patch tracking system a new ticket [DNX#2006101142000031] was created:

<snip>

Hi,

this patch adds support for Micrel's switches KS8893 and KS8993 and for Micrel's PHYs KS8721 and KS8001. The drivers can be used with AT91RM9200 based boards.

Using these drivers requires to apply the CONFIG_PHY_ADDR patch that was send to the list on 11.08.06.

Best Regards Mirco
