In this paper, we are going to explain TrenchBoot implementation for AMD and
prove a boot chain leveraging it. We will outline how this solution coexists
with open-source firmware like coreboot in flash, explain required bootloader
extension based on GRUB2 implementation, discuss Landing Zone (LZ) secure
loader implementation and required Linux kernel modifications.
Finally, we will explain what benefits this solution has over the previous OSLO,
Flicker, Soft Cards and others.
