- 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.
