[lacie-nas] U-boot image with GPT for NS2 requested

[Tjalling]

Thanks for your advice Frans.

I indeed have a mainline U-boot image installed (done by Simon 4 years
ago), and it doesn't seem to have the bubt command. I will wait if anybody
comes with more/other advice otherwise I'll just try and hope for the best.

I will let you guys know if it worked.

cheers, Tjalling
