Subject: [RFC 0/2] of: Add whitelist

Here's a proposal for a whitelist to lock down the dynamic device tree.

For an overlay to be accepted, all of its targets are required to be
on a target node whitelist.

Currently the only way I have to get on the whitelist is calling a
function to add a node.  That works for fpga regions, but I think
other uses will need a way of having adding specific nodes from the
base device tree, such as by adding a property like 'allow-overlay;'
or 'allow-overlay = "okay";' If that is acceptable, I could use some
advice on where that particular code should go.
