Hi Krzysztof,

I took a look at these and am not convinced this is right:

> 1. Fix boot of Exynos7 due to wrong address/size of memory node,

The current state is clearly broken and a fix is needed, but
I'm not sure this is the right fix. Why do you have 32-bit physical
addressing on a 64-bit chip? I looked at commit ef72171b3621
that introduced it, and it seems it would be better to just
revert back to 64-bit addresses.

No problem

IIRC, an interrupt-controller is required to have a #address-cells
property, even if that is normally zero. I don't remember the
details, but the gic binding lists it as mandatory, and I think
the PCI interrupt-map relies on it. I would just drop this patch.
