I've prepared another path to add the support for the sam440ep;
shortly I've merged arch/powerpc/boot/sam440ep.c in
arch/powerpc/boot/cuboot-sam440ep.c; I've inserted the code to make
the rtc works directly in arch/powerpc/platforms/44x/sam440ep.c (so
there isn't any arch/powerpc/sysdev/sam440ep.c

How does Alsa allocate such SG ?

The platform file is so small (and similar to other platform files) that
I wonder if we can move toward something aking to the 5200 simple
platform, that is have one platform with a list of matches.
Now, the s

Urgh. Could you split this into a number of smaller patches, each with
a proper commit message that doesn't break the build on its own?
