[maemo-developers] DSP vs. ARM endianness and struct packing

I did some experimentation a while back with DSP <-> ARM communication
via mmap'ed memory, in my case I was working on using the DSP for rgb
to yuv conversion. Another big gotcha to look out for is 64k
boundaries. The DSP (at least in the 770) just can't naturally deal
with object bigger than 64k, so you will get very bizarre results if
you run into this limitation.
