[PATCH v2 0/4] xen/arm: Prevent Dom0 to be loaded when using dom0less

[Luca Fancellu <luca.fancellu@xxxxxxx>]

This is the v2 of xen/arm: Prevent Dom0 to be loaded when using dom0less
previously pushed.

The aim of this serie is to prevent the creation and run of the domain 0 (Dom0)
when the system configuration to be used is dom0less, that is when the device
tree declares at least one domU and no Dom0.

Changes in v2 are:
 - Moving the dom0 creation in a proper function
 - Handle the case of having an hardware_domain NULL
 - Be sure that the domain id 0 is never allocated
 - Modify documentation about dom0less

Luca Fancellu (4):
  xen/arm: Move dom0 creation in domain_build.c
  xen/arm: Handle cases when hardware_domain is NULL
  xen/arm: Reserve domid 0 for Dom0
  xen/arm: Prevent Dom0 to be loaded when using dom0less
