grub2/0013-tpm-i386-pc-diskboot-img.patch
Michael Chang b046f3779b Accepting request 529824 from home:michael-chang:bsc:1052401 
- Build diskboot_tpm.img as separate image to diskboot.img to prevent failure
  in booting on some bogus firmware. To use the TPM image you have to use
  suse-enable-tpm option of grub2-install (bsc#1052401)
  * 0013-tpm-i386-pc-diskboot-img.patch
