This work being submitted in this series was made possible with a great thanks to Star Lab Cop ration and their generous funding of this project.
The patch series is based on the existing xsm series for starting the idle domain privileged. After that, the first four commits were previously submitted as an RFC and expanded by an additional commit to refactor xen commandline handling. The remaining preliminary patches are FDT refactoring and a doc update. From there is where the series begins to morph x86 arch to support building multiple domains at boot. This series has been fairly well tested using qemu with a multiboot1 bootoader and under EFI + GRUB multiboot2 boot. While there are likely some rough spots remaining in the series, it is at a point now where the series should be reviewed, exercised, and tested for consideration into tree.
