[U-Boot] [[PATCH 7/7] keystone2: net: add keystone ethernet driver
Murali Karicheri
m-karicheri2 at ti.com
Fri Feb 7 22:52:25 CET 2014
The network driver consists of multicore navigator
driver and the ethernet sub system driver. Multicore
navigator consists of Network Coprocessor (NetCP) and
Queue Manager sub system. More details on the hardware can
be obtained from the following links:-
Network Coprocessor: http://www.ti.com/lit/pdf/sprugz6
Multicore Navigator: http://www.ti.com/lit/pdf/sprugr9
Multicore navigator driver implements APIs to configure
the Queue Manager and NetCP Pkt DMA. Ethernet driver
configures the CPSW, SGMI and Phy and uses the the Navigator
APIs. The driver supports 4 Ethernet ports and can work with
only one port at a time.
Port configurations are defined in board.c.
