Subject: [PATCH 0/2] Platform integrity information in sysfs (version 9)

This patch serie adds a misc kernel module and extends the intel-spi drivers
to publish platform integrity data in the sys-fs.
Please check the comments in the following patches of this serie for further
details.

Daniel Gutson (2):
  Platform integrity information in sysfs (version 9)
  This patch exports the BIOS Write Enable (bioswe), BIOS Lock Enable
    (biosle), and the SMM BIOS Write Protect (SMM_BIOSWP) fields of the
    BIOS Control register using the platform-integrity misc kernel
    module. The idea is to keep adding more flags, not only from the BC
    but also from other registers in following versions.
