Hi,

I would recommend that you make your root #address-cells and #size-cells equal
to 2, as that will simplify matters later if/when you need to add anything
beyond the first 4GB for some particular board.
If everything in the SoC falls within the first 4GB you can have a ranges
property on your /soc node and have only one cell below that.

Shouldn't the virtual CPU interface also be 0x2000 long?

Ok, will update.

Right, according to the GIC-400 r0p1 TRM, section 3.2 register map,
shows that
0x0000 - 0x0fff Reserved
0x1000 - 0x1fff Distibutor
...
So even though the GIC address starts at 0xffff8000, the first usable
register is at 0xffff9000. I'll have to ask the hw folks if the
0xffff8000 represents the distributor or the reserved block.
