There are two enable methods supported by ARM64 Linux; psci and spin-table. The latter is simpler and easier to use for quick SoC bring-up.

So, I used the spin-table for my first ARMv8 SoC porting, but I found its support in U-Boot was poor. It is true there exists a code fragment for the spin code in arch/arm/cpu/armv8/start.S, but I see some problems:

Is part of the motivation for this approach to boot an ARMv8 system without using the ARM Trusted Firmware?
