The following pcpu related interfaces are moved into common: - common/cpu.c::start_pcpus - include/common/cpu.h::get_pcpu_id - include/common/cpu.h::set_current_pcpu_id Their arch specific implementations are moved into arch/$(ARCH): - arch/$(ARCH)/cpu.c::arch_start_pcpu - include/arch/$(ARCH)/asm/cpu.h::arch_get_pcpu_id - include/arch/$(ARCH)/asm/cpu.h::arch_set_current_pcpu_id The following interface is moved into common: - pcpu_set_current_state (from arch/x86/cpu.c -> common/cpu.c) The following MACROs are moved into include/common/cpu.h: - CPU_UP_TIMEOUT - CPU_DOWN_TIMEOUT - BSP_CPU_ID - INVALID_CPU_ID Tracked-On: #8791 Signed-off-by: Jian Jun Chen <jian.jun.chen@intel.com> Acked-by: Wang, Yu1 <yu1.wang@intel.com>
