What's this reservation for?
Given you're using PSCI I can't see why we'd expect the kernel to map
but not use some memory.

You shouldn't need those bootargs; "earlyprintk" does nothing on arm64.

I believe the size of the cpu interface (the second reg entry) should be
0x2000, as GICC_DIR is at offset 0x1000.
Otherwise this looks fine.
Thanks,
