It's somehow always on the backburner, but I already started fixing the things 
you pointed out. Though I'll be in Portland, Mountain View and San Francisco 
for the next two weeks, so will only be able to resend the fixes after that.

Kever  already found out, that the sd read the bootrom does fails when trying 
to load the uboot from the spl. I'm still trying to investigate this [same 
Portland remark applies], but if you're ok with stuff going in in this state, 
that is definitly fine by me, as it spares me from sending the full series all 
the time ;-)
