How to use smbios

[jack206]

I want to use smbios to get bios info.
here is my smbios-mdr_%.bbappend：
PACKAGECONFIG:append = " smbios-ipmi-blob"
PACKAGECONFIG:remove = " cpuinfo"
image.bbappend:
OBMC_IMAGE_EXTRA_INSTALL:append = " smbios-mdr"
OBMC_IMAGE_EXTRA_INSTALL:append = " phosphor-ipmi-blobs"
here is log:
