From: Lorenzo Pieralisi lorenzo.pieral...@arm.com
Since the introduction of /cpu nodes bindings for ARM and the
corresponding parse function arm_dt_init_cpu_maps(), the cpu_logical_map
and the number of possible CPUs are set according to the DT /cpu
nodes entries. Currently most of the existing
SCU based detection only works with Cortex-A9 MP and it doesn't
support ones with multiple clusters. The only way to detect number of
CPU core correctly is with DT /cpu node. If DT /cpu node based
detection fails, we just simply fall back a single core in Tegra SoCs.
