Change Details

We assume the boot CPU is always CPU 0 on arm64. To allow for this iterate through the cpu list twice. Once to find CPU0 and record any needed data, and once to find the non-boot CPUs. While here extract the FDT CPU init code into a new function to simplify cpu_mp_start.

We assume the boot CPU is always CPU 0 on arm64. To allow for this reserve cpuid 0 for the boot CPU in the ACPI and FDT cases but otherwise start the CPU as normal. We then check for the boot CPU in start_cpu and return as if it was started. While here extract the FDT CPU init code into a new function to simplify cpu_mp_start and return FALSE from start_cpu when the CPU fails to start.
