[U-Boot] available memory gets adjusted - why?

[Dunda, Matthias]

Hi all-

after issuing the boot command I get 

WARNING: adjusting available memory to 3000000

I do have 2 Gig on my board and I set that in the appropriate configs.

What's the reason why U-Boot adjusts the size and how can I fix this? 

I mean, U-Boot itself runs from 0x7ff3.... so the memory is there!

Thanks
Matthias
