| 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. |
