On our Zynq design here we ended up being unwilling to use platform
generation from Vivado. Basically all our IP was custom, so there was
no win at all to invoking the complexity of the automatic tools.
Thus we write the DT by hand, and our DT is complex, integrating
peripherals that span two FPGAs.
I think the in-kernel DT should use the kernel conventions, which
means using #include and the binding constants over magic values.
