Message-ID: <20070228224031.GA8233@xyzzy.farnsworth.org>

Subject: [PATCH 1/2] mv643xx_eth: move mac_addr inside of mv643xx_eth_platform_data
The information contained within platform_data should be self-contained.
Replace the pointer to a MAC address with the actual MAC address in
struct mv643xx_eth_platform_data.
