Due to some parts of Exynos SoC support designed originally in a non-scalable way, relying on 1:1 mapping between value returned by cpu_logical_map() and CPU IDs as seen by PMU and GIC, trying to specify CPU topology in device tree caused various boot-up issues on Exynos SoCs, ranging from CPUs other than 0 failing to boot to crashes due to GIC driver accessing registers out of range. This series attempts to fix aforementioned issues by removing incorrect assumptions from Exynos SoC core code and GIC driver and then adding CPU topology data to device tree sources of Exynos4.
