Hi,
There is no module images name when the latest tboot is used in Centos 7.2.
In Centos 7.2, it seems that grub2 does not pass boot image name to tboot.
When loading module images in Centos 7.2, the tboot shows "TBOOT: checking if
module is an SINIT for this platform..." in tboot log.
But in Centos 6.5, grub does pass boot image name to tboot.
When loading module images in Centos 6.5, the tboot shows "TBOOT: checking if
module /initramfs-2.6.32-431.el6.x86_64.img is an SINIT
for this platform..." in tboot log.

Here is a patch against 1.9.5 which corrects the problem:
