As per ARM documentation PPI(0) ID27 - global timer interrupt is rising-edge sensitive. PPI(2) ID29 - twd interrupt is rising-edge sensitive. and the same is proved by GIC distributor register value GIC_DIST_CONFIG(0xC04) = 0x7DC00000. Hence, set IRQ triggering type to IRQ_TYPE_EDGE_RISING for ARM TWD and Global timers.
