From f84fdff0fdcda7e509ce530e0ee612233a2104fb Mon Sep 17 00:00:00 2001 From: Xiaoyan Zhang Date: Wed, 22 Aug 2012 18:47:22 +0800 Subject: driver: add PPI support in tpm driver The Physical Presence Interface enables the OS and the BIOS to cooperate and provides a simple and straightforward platform user experience for administering the TPM without sacrificing security. V2: separate the patch out in a separate source file, add #ifdef CONFIG_ACPI so it compiles out on ppc, use standard error instead of ACPI error as return code of show/store fns. V3: move #ifdef CONFIG_ACPI from .c file to .h file. V4: move tpm_ppi code from tpm module to tpm_bios module. V5: modify sys_add_ppi() so that ppi_attr_grp doesn't need to be exported Signed-off-by: Xiaoyan Zhang Signed-off-by: Kent Yoder --- drivers/char/tpm/Makefile | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'drivers/char/tpm/Makefile') diff --git a/drivers/char/tpm/Makefile b/drivers/char/tpm/Makefile index 9080cc44e3c4..5b3fc8bc6c13 100644 --- a/drivers/char/tpm/Makefile +++ b/drivers/char/tpm/Makefile @@ -4,7 +4,7 @@ obj-$(CONFIG_TCG_TPM) += tpm.o ifdef CONFIG_ACPI obj-$(CONFIG_TCG_TPM) += tpm_bios.o - tpm_bios-objs += tpm_eventlog.o tpm_acpi.o + tpm_bios-objs += tpm_eventlog.o tpm_acpi.o tpm_ppi.o else ifdef CONFIG_TCG_IBMVTPM obj-$(CONFIG_TCG_TPM) += tpm_bios.o -- cgit v1.2.3
