Currently, there are two different fields in the mv643xx_eth_platform_data struct that together describe the PHY address -- one field (phy_addr) has the address of the PHY, but if that address is zero, a second field (force_phy_addr) needs to be set to distinguish the actual address zero from a zero due to not having filled in the PHY address explicitly (which should mean 'use the default PHY address'). If we are a bit smarter about the encoding of the phy_addr field, we can avoid the need for a second field -- this patch does that. Signed-off-by: Lennert Buytenhek <buytenh@marvell.com>
