Krzysztof Kozlowski 97d5c7a77e Documentation: EXYNOS: Update bootloader interface on exynos542x ... Update the documentation about: 1. Usage of PMU_SPARE2 register. Bootloaders on Exynos542x-based boards often use the register PMU_SPARE2 (0x908) in the same way as on Exynos3250: as a indicator the secondary CPU was booted on. The bootloader will set this value to non-zero, after sucessfull power up of secondary CPU. In the same time this booted CPU will stuck (spin) waiting for software reset. 2. Exynos542x entry address for secondary CPU boot up after system suspend (with MCPM enabled and in non-secure mode). See arch/arm/mach-exynos/mcpm-exynos.c for source code.
