Ok thanks a lot Fabio!

So I will try tomorrow to build the latest mainline u-boot and load it in my evaluation board.

I found a recent commit that could explain the issue and its resolution:
http://git.denx.de/?p=u-boot.git;a=patch;h=c6d3d812fefabd0807fca485fef89e0c32ed4190
I checked my code and I already had this new define... I do not see which difference with u-boot-fslc could have made it work...
