This series came from part of the work of removing duplications between boot code and rewriting part of code from assembly to C. First 2 patches rework BIOS/PVH paths to reuse some code. Third patch rewrites EFI code in pure C. Changes since v1, more details in specific commits: - style updates; - comments and descriptions improvements; - other improvements. Changes since v2: - rebased on master, resolved conflicts; - add comment on trampoline section.
