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

[Joe Culler]

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.
