When I first started up my board (ebony) with u-boot, I set the Ethernet address incorrectly. Instead of using the colon format (00:04:ac:e3:1c:4c) I entered the hex values all together(0004ace31c4c). So I think now the Ethernet address environment variable is permanently wrong. When I use the command bdi it says ethhaddr =3D 4c:00:00:00:00:00. Is there a way to fix this, may be by using the JTAG hardware debugger or something?

Assuming you store your environment in flash:

- use "protect off" command to make sector containing the environment writable - use "erase" to erase sector containing the environment - "reset", and the board will come up with it's default environment

Just using "mw 0 0;cp 0 <addr> 1" instead of the erase will work, too, as it will overwrite the CRC32 checksum.

If you don;t want to lose your existting environment definitions, trickier approaches are possible, too: copy the environment to RAM, edit it using "mm", compute a new checksum and store it to the start of the envrionment (easy to be done with "crc32" command), and write it back to where you store it (flash, eeprom, etc.).
