Initially, we add an IPI based implementation, as the GIC code needs modification to support the generation of FIQ IPIs, and not all ARM platforms have the ability to raise a FIQ in the non-secure world. This provides us with a "best efforts" implementation in the absence of FIQs. Signed-off-by: Russell King --- Reading git-diff-tree failed
