[PATCH 0/3] x86/boot: Reduce assembly code

Posted by Frediano Ziglio 1 year, 1 month ago

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.

Frediano Ziglio (3):
  x86/boot: Initialise BSS as soon as possible
  x86/boot: Refactor BIOS/PVH start
  x86/boot: Rewrite EFI start part in C
