Updates all XML descriptions to latest schema version and
also includes adaptions to the test XML descriptions for
testing the new Xen guest and server setup
The vboot firmware setup was a workaround on arm for the
chromebook platform several years ago. From a todays
perspective the setup and the way to boot would be different
and obsoletes the special case implementation. Thus this
is gone now. Related to Issue #234
Triggered by the firmware="vboot" setup an EFI setup plus a
raw partition without filesystem is created as first partition.
The size of the partition can be controlled by the vbootsize
attribute. The vboot feature is used by the arm architecture
to provide a space in the partition table for custom code as
required by e.g the chromebook. The final customization of the
vboot space is board specific and can't be implemented in a
generic way in kiwi. For finalizing the vboot space the script
hooks editbootconfig and editbootinstall can be used
