[U-Boot] Can u-boot access Linux's mtd partition?

Hi,

If I've already created some configuration files such as mac address in mtd2 partition. For example: 0x00000000-0x00040000 : "Bootloader" 0x00040000-0x02000000 : "User config"

Does u-boot can access mtd2 partition and read the mac address from the configure file? If so, would anyone tell me how to do or what similar code can I refer to in u-boot? Thanks. If not, can u-boot read the mac address from the eeprom instead of set it manually?

Thank you,

Best regards, Joe.
