Pierre Gondois 3ebe1ff5c9 DynamicTablesPkg: FdtHwInfoParser: Generic Timer Parser ... The Generic Timer Description Table (GTDT) is a mandatory table required for booting a standards-based operating system. It provides an OSPM with information about a system's Generic Timer configuration. The Generic Timer (GT) is a standard timer interface implemented on ARM processor-based systems. The GTDT provides OSPM with information about a system's GT interrupt configurations, for both per-processor timers, and platform (memory-mapped) timers. The Generic Timer information is described in the platform Device Tree. The Device Tree bindings for the Generic timers can be found at: - linux/Documentation/devicetree/bindings/timer/arm,arch_timer.yaml The FdtHwInfoParser implements a Generic Timer Parser that parses the platform Device Tree to create a CM_ARM_GENERIC_TIMER_INFO object. The CM_ARM_GENERIC_TIMER_INFO object is encapsulated in a Configuration Manager descriptor object and added to the platform information repository. The platform Configuration Manager can then utilise this information when generating the GTDT table. Note: The Generic Timer Parser currently does not support parsing of memory-mapped platform timers.
