Secure Boot documentation for Bay Trail

Hi all,

I'm reading through Bay Trail FSP release notes FSP/BayTrailFspReleaseNotes.pdf at BayTrail · IntelFsp/FSP · GitHub

and see that it mention 2 documents that I cannot find:

Secure Boot Readme - README.coreboot_secureboot.txt

and

#558081_Enabling_Secure_Boot_with_Intel_FSP_and_coreboot_for_Intel_Atom_Processor_E3800_Product_Family_Implementation_Guide-Rev-1.0.pdf

Both google and RDC say nothing about those. Where I can find them ?
