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