Thanks for your reply, Scott,

one question though: I am NOT using the bootwrapper, I'm instead feeding  
dtb and uImage directly to u-boot. This probably means that I should fill  
in lots of stuff manually into dts, right? But, (and please forgive my  
ignorance) who does actually fill in stuff (like e.g. clock-frequency or  
bus-frequency), except, of course, from the trivial modifications u-boot  
does to dtb? The wrapper script seems to do nothing more that simply  
running dtc on dts.

Thanks again

Alex
