+ means it is 0 when the IRQ is not active. This makes the wire-AND
+ logic always assert IRQ7 to CPU even if there is no request from the
+ switch. Since the compact flash and the switch share the same IRQ,
+ the Linux kernel will think that the compact flash is requesting irq
+ and get stuck when it tries to clear the IRQ. Thus we need to set
+ the L2_IRQ0 and L2_IRQ1 to active low.
+
+ The following code sets the L1_IRQ and L2_IRQ polarity to active low.
+ Without this code, compact flash will not work in Linux because
+ unlike U-Boot, Linux uses the IRQ, so this code is necessary if we
+ don't enable compact flash for U-Boot.
