This is weird - it works on mine.

What's in your /memory properties? Especially "available" and "reg"?
Also, what's in / "#size-cells" and "#address-cells" ?

Finally, does it work if you remove this:
        if (((regcnt >> 2) % (acells + scells)) != 0) {
                aprint_normal("messed up 'available' property detected\n");
                acells = 1;
        }
... and just set acells to 1 there?

I'm not sure if "available" is supposed to list memory above 4GB. On
mine it doesn't even though "reg" contains 64bit addresses and there is
high memory.

have fun
