Content-Type: multipart/mixed; boundary="------------030507030907080301050403" List-Id: Linux on PowerPC Developers Mail List List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , This is a multi-part message in MIME format. --------------030507030907080301050403 Content-Type: text/plain; charset=ISO-8859-15; format=flowed Content-Transfer-Encoding: 8bit Here is a patch for the lite5200 to get the FEC working again for kernel >=2.6.24. It was created against Linux 2.6.24. The FEC driver is also compatible with the MPC5200, not only with the MPC5200B, so an according entry was added to the drivers matching list. Furthermore the settings for the PHY were entered in the dts file for the Lite5200. Note, that this is not exactly the same as in the Lite5200B, because the PHY is located at f0003000:01 for the 5200, and at :00 for the 5200B. I could test the patch on a Lite5200 and a Lite5200B, both booted a kernel via tftp and mounted the root via nfs successfully. I hope, you can include the patch into the official tree.
