u-boot and gpt

["kqt4at5v@gmail.com" <kqt4at5v@gmail.com>]

I realize this is not a Debian question but I am hoping some has run into 
this. I installed u-boot

Marvell>> version

U-Boot 2011.12 (Jan 08 2012 - 21:46:50)
Marvell-GuruPlug
gcc (Debian 4.6.2-9) 4.6.2
GNU ld (GNU Binutils for Debian) 2.22

And installed Debian with no trouble but u-boot can not see the GPT 
partition table. From what I read GPT support was added to u-boot several 
years ago.  Is there something I need to do to get this to work?
