Exynos 9810 is an ARMv8 mobile SoC found in various Samsung devices, such as Samsung Galaxy S9 (starlte), S9 Plus (star2lte), Note 9 (crownlte) and perhaps others. Add minimal support for this SoC, including basic stuff like: - PSCI for bringing up secondary cores - ARMv8 generic timer - GPIO and pinctrl. The firmware coming with the devices based on this SoC is buggy and doesn't configure CNTFRQ_EL0, as required by spec, so it's needed to hardcode the frequency in the timer node.
