U-Boot config options used in fec_mxc.c
|
|
|
|
|
|
|
|
|
|
CONFIG_FEC_MXC
|
|
|
|
|
Selects fec_mxc.c to be compiled into u-boot. Can read out the
|
|
|
|
|
ethaddr from the SoC eFuses (see below).
|
|
|
|
|
|
|
|
|
|
CONFIG_MII
|
|
|
|
|
Must be defined if CONFIG_FEC_MXC is defined.
|
|
|
|
|
|
|
|
|
|
CONFIG_FEC_XCV_TYPE
|
|
|
|
|
Defaults to MII100 for 100 Base-tx.
|
|
|
|
|
RGMII selects 1000 Base-tx reduced pin count interface.
|
|
|
|
|
RMII selects 100 Base-tx reduced pin count interface.
|
|
|
|
|
|
|
|
|
|
CONFIG_FEC_MXC_SWAP_PACKET
|
|
|
|
|
Forced on iff MX28.
|
|
|
|
|
Swaps the bytes order of all words(4 byte units) in the packet.
|
|
|
|
|
This should not be specified by a board file. It is cpu specific.
|
|
|
|
|
|
|
|
|
|
CONFIG_PHYLIB
|
|
|
|
|
fec_mxc supports PHYLIB and should be used for new boards.
|
|
|
|
|
|
|
|
|
|
CONFIG_FEC_MXC_NO_ANEG
|
|
|
|
|
Relevant only if PHYLIB not used. Skips auto-negotiation restart.
|
|
|
|
|
|
|
|
|
|
CONFIG_FEC_MXC_PHYADDR
|
|
|
|
|
Optional, selects the exact phy address that should be connected
|
|
|
|
|
and function fecmxc_initialize will try to initialize it.
|
|
|
|
|
|
|
|
|
|
CONFIG_FEC_FIXED_SPEED
|
|
|
|
|
Optional, selects a fixed speed on the MAC interface without asking some
|
|
|
|
|
phy. This is usefull if there is a direct MAC <-> MAC connection, for
|
|
|
|
|
example if the CPU is connected directly via the RGMII interface to a
|
|
|
|
|
ethernet-switch.
|
|
|
|
|
|
|
|
|
|
Reading the ethaddr from the SoC eFuses:
|
|
|
|
|
if CONFIG_FEC_MXC is defined and the U-Boot environment does not contain the
|
|
|
|
|
ethaddr variable, then its value gets read from the corresponding eFuses in
|
|
|
|
|
the SoC. See the README files of the specific SoC for details.
