SUMMARY:Boot Chains and Build Systems - Jiji Freya Daniel Maslowski

DESCRIPTION:It is clear that booting a system based on an application proc
 essor requires multiple binaries and possibly multiple hardware components
  - at the very least\, one to initialize the DRAM and one to run in it. Th
 is implies that the various components of the chain\, however many\, need 
 to be aware of the respective next and previous one somehow: Any component
  has to know the source\, the protocol\, and the destination for loading t
 he next one\, and the build system needs to create an overall image for th
 e target platform\, typically also requiring extra data structures that ad
 here to the mask ROM or other prior loader\, possibly containing signature
 s or similar for a secure boot flow.\n\nWith this presentation\, we summar
 ize the development of the oreboot and LinuxBoot build systems over time\,
  what has been considered and attempted\, and how things worked out\, and 
 compare with other firmware projects\, such as U-Boot and coreboot. We exp
 lain why it is important to know and understand the full chain and its bui
 ld process for both security and reliability\, and finally provide a list 
 of necessary features to be worked on for the future.
