Yep.

That's what mem= or device tree reservations are for: Keep root Linux
away from some memory that can then be used for non-root inmates and the
hypervisor itself.

Check the device tree of your target.

pin_base for the first gicd is always 32 (first SPI). The pin_bitmap of
the root cell should cover all possible SPIs. If those do not fit into
one irqchip, add another one with an appropriate pin_base.
For non-root cells, you only specify the SPIs that those should "steal"
from the root cell.
