- This driver supports Designware Ethernet Controller provided by Synopsis.
- The driver is enabled by CONFIG_DESIGNWARE_ETH.
- The driver has been developed and tested on SPEAr platforms. By default, the
- MDIO interface works at 100/Full. #defining the below options in board
- configuration file changes this behavior.
- Call an subroutine from respective board/.../board.c
- designware_initialize(u32 id, ulong base_addr, u32 phy_addr);
- The various options suported by the driver are
- 1. CONFIG_DW_ALTDESCRIPTOR
- Define this to use the Alternate/Enhanced Descriptor configurations.
- 1. CONFIG_DW_AUTONEG
- Define this to autonegotiate with the host before proceeding with mac
- level configuration. This obviates the definitions of CONFIG_DW_SPEED10M
- and CONFIG_DW_DUPLEXHALF.
- 2. CONFIG_DW_SPEED10M
- Define this to change the default behavior from 100Mbps to 10Mbps.
- 3. CONFIG_DW_DUPLEXHALF
- Define this to change the default behavior from Full Duplex to Half.
- 4. CONFIG_DW_SEARCH_PHY
- Define this to search the phy address. This would overwrite the value
- passed as 3rd arg from designware_initialize routine.
