That's right. This is the cnusers.org SDK that we've included in the
kernel.
: Warner, is this what you would see on happen on under 1.8.1?
No. I have older uboot systems, and they refuse to properly load the
kernel. see below...

I am seeing this when I boot a 32-bit kernel on two of the three
boards I have access to (both of them, btw, have older uboot loaders
on them).
The problem here is that cvmx_phys_to_ptr only supports direct
mapping, so we can only use the first 512MB of memory. Juli and I
have talked about clamping the available memory to using only the
first 512MB on 32-bit kernels, but we don't like this idea and are
casting about for others.
The 64-bit kernel doesn't suffer this limitation.
