Add ns-interrupts-action property to SP manifests Set non-secure interrupt action to signaled which means SPs can be preempted by non-secure interrupts. This prevents the starvation of the Linux scheduler during longer calls to secure partitions. Signed-off-by: Imre Kis <imre.kis@arm.com> Change-Id: I71f4e46ebbe29f96d0d939b99b3cd2da17e30cc4
