37.3.2 Getting a MAC Address
The following statement gets the MAC address through the OCOTP (IC Identification)
by default for i.MX 6.
The MAC address can be set through bootloader such as u-boot. FEC driver will use it to
confiure the MAC address for network devices. i.MX 6 user needs to provide MAC
address by kernel command line so that user can use sb_loader to load kernel and run it
without bootloader interaction.
Due to certain pin conflicts (FEC RMII mode need to use GPIO_16 or RGMII_TX_CTL
pin as reference clock input/output channel), the one of the both pins cannot connect to
branch lines for other modules use because the branch lines have serious influence on
clock.
