Earlier falcon HAL ops were embedded in the falcon structure. For clear separation of common and HAL these ops will have to be accessed through g->ops.falcon interfaces. With these changes nvgpu_falcon_* functions directly call falcon gpu ops functions for falcon. Falcon registers and HAL functions are exported from falcon_gk20a.h. HAL files per platform are now updated with base falcon functions. Falcon software state such as is_falcon_supported, is_interrupt_enabled and flcn_base are set from software init functions defined per chip.
