I didn't see this comment.
With my patch, the "ide reset" command recognize nicely a 3TB harddrive.
Else, it reports the size % 2TB and then u-boot reports error in the GPT.

I can read the GPT and boot from a loaded file from the first partition.
However, an "ext2ls" on a partition at the end of the disk outputs garbage.

At least, the patch allow to use the first 2 TB for booting.

Regards,
