/** @file Register names for PCH LPC/eSPI device Conventions: - Register definition format: Prefix_[GenerationName]_[ComponentName]_SubsystemName_RegisterSpace_RegisterName - Prefix: Definitions beginning with "R_" are registers Definitions beginning with "B_" are bits within registers Definitions beginning with "V_" are meaningful values within the bits Definitions beginning with "S_" are register size Definitions beginning with "N_" are the bit position - [GenerationName]: Three letter acronym of the generation is used . Register name without GenerationName applies to all generations. - [ComponentName]: This field indicates the component name that the register belongs to (e.g. PCH, SA etc.) Register name without ComponentName applies to all components. Register that is specific to -H denoted by "_PCH_H_" in component name. Register that is specific to -LP denoted by "_PCH_LP_" in component name. - SubsystemName: This field indicates the subsystem name of the component that the register belongs to (e.g. PCIE, USB, SATA, GPIO, PMC etc.). - RegisterSpace: MEM - MMIO space register of subsystem. IO - IO space register of subsystem. PCR - Private configuration register of subsystem. CFG - PCI configuration space register of subsystem. - RegisterName: Full register name.
