The set of available commands depends on your board configuration. Probably the eeprom command is not selected in your board config file. Eventually there is even no EEPROM on your board at all. We don't know - it's your hardware.
as I got MAC addresses don't match.
Then set it correctly in the environment.
Can u-boot allow me to change HW MAC address?
Yes, on some systems.
eth0: Invalid ethernet MAC address. Please set using ifconfig
But this won't help you. You still need to implement a way that the Linux driver sets a correct MAC address. Solutions have been posted on the ARM mailing list. See the links and suggestions provided before.
