Thanks, Sandeep

-----Original Message----- From: Paulraj, Sandeep Sent: Tuesday, May 12, 2009 11:46 AM To: u-boot@lists.denx.de Cc: Paulraj, Sandeep Subject: [PATCH] DaVinci Network Driver Updates

Different flavours of DaVinci SOC's have differences in their EMAC IP This patch does the following

1. Updates base addresses for DM365
2. Updates MDIO frequencies for DM365 and DM646x
3. Update EMAC wrapper registers for DM365 and DM646x

Patch applies to u-boot-net git. the EMAC driver itself will be updated shortly to add support for DM365 and DM646x
