Cleanup the logic to fill those, as they should be handled independently. This is a preparation for a future patch that will shift those fields to the HEST init function call. Signed-off-by: Mauro Carvalho Chehab Reviewed-by: Jonathan Cameron --- Chenges from v10: - Some changes got moved to the previous patch. Changes from v8: - Non-rename/cleanup changes merged altogether; - source ID is now more generic, defined per guest target. That should make easier to add support for 86.
