This is a policy decision for ArmPkg/PlatformBootManagerLib, which
affects ArmVirtXen and probably a number of physical ARM platforms. I'm
OK with that.
This patch does two things (which I don't mean as a request to split the
patch), it clears LOAD_OPTION_ACTIVE, and sets LOAD_OPTION_HIDDEN. From
the spec:
- "If a load option is marked as LOAD_OPTION_ACTIVE, the boot manager
will attempt to boot automatically using the device path information in
the load option. This provides an easy way to disable or enable load
options without needing to delete and re-add them."
- "If any Boot load option is marked as LOAD_OPTION_HIDDEN, then the
load option will not appear in the menu (if any) provided by the boot
manager for load option selection."
So this change will both stop auto-booting the shell, and hide it from
the UiApp menu. I'm OK with that. (Maybe add this one sentence to the
commit message.)
