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.
