On a related note, we are discussing the addition of 2 new device-tree
properties
with Pete Heyrman and his fellows that should simplify the determination of the
set of required nodes.
* One property would provide the total/max number of nodes needed by the kernel
on the current hardware.

Here is the information from 2 different kernels. I have not been able to retrieve
the information matching yesterday's attachments, yet, as those dumps were
acquired in April.
Attached please find 2 dumps of similar material from kernels running with my
current patches (Linux 4.4, Linux 4.12).

I am running into this problem on PowerPC systems where Balbir's patch set

one way or the other, with this patch removed.
