Subject: [PATCH] hw/arm/armsse: Indirect irq_is_common[] through ARMSSEInfo
MIME-Version: 1.0
Content-Type: text/plain; charset=utf8
Content-Transfer-Encoding: 8bit

The SSE-300 has a slightly different set of shared-per-CPU interrupts,
allow the irq_is_common[] array to be different per SSE variant.
