No /chosen/stdout-path?
Does your UART driver support earlycon?

The secondary CPUs need an enable-method. Are you using PSCI or
spin-table?
Which exception level do the CPUs enter the kernel?

This should be "arm,armv8-timer".

NAK. CNTFRQ should be programmed on all CPUs prior to entering the
kernel, per the boot protocol. You should not need clock-frequency here.

This string isn't documented (but seems to be supported by the GIC
driver).
How does this differ from other GIC implementations?

No GICH, GICV, maintenance interrupt?
Minor nit, but I'd prefer if the reg entries were on individual lines as
happens in other dts.
Thanks,
Mark.
