Paul Menzel (paulepanter@users.sourceforge.net) just uploaded a new patch set to gerrit, which you can find at http://review.coreboot.org/3274 -gerrit commit ae3e0ecfd32ff75a4cadb5f8f7b3adae32f7324f Author: Denis 'GNUtoo' Carikli <GNUtoo@no-log.org> Date: Sun Apr 21 19:32:02 2013 +0200 Lenovo X60: permit to compile the x60 code without SMM. Removing or commenting `HAVE_SMI_HANDLER` from the Kconfig file – by default .config –, results in the following build error. CC cbfs/fallback/coreboot_ram.debug build/generated/coreboot_ram.o: In function `i82801gx_lock_smm': src/southbridge/intel/i82801gx/lpc.c:350: undefined reference to `smm_lock' build/generated/coreboot_ram.o: In function `write_acpi_tables': src/mainboard/lenovo/x60/acpi_tables.c:231: undefined reference to `smm_setup_structures' build/generated/coreboot_ram.o: In function `initialize_cpus': src/cpu/x86/lapic/lapic_cpu_init.c:562: undefined reference to `smm_init' build/generated/coreboot_ram.o: In function `acpi_resume': src/arch/x86/boot/acpi.c:633: undefined reference to `smm_setup_structures' collect2: error: ld returned 1 exit status Adding the following guards #if CONFIG_HAVE_SMI_HANDLER […] #endif at the appropriate places, results in a successful build.
