Based on the discussion in the Xen Summit [1], sending this series out after
addressing the comments in v6 [2] as the preparation work to add MPU support.
The series passed the GitLab CI check in [3].
Mostly code movement and function folding, with some of Kconfig and build
system (mainly Makefiles) adjustment.
This series is based on:
ffa1437686 tools/xenpvboot: remove as unable to convert to Python 3
