+   i) Freescale QUICC Engine module (QE)
+   This represents qe module that is installed on PowerQUICC II Pro.
+   Hopefully it will merge backward compatibility with CPM/CPM2.
+   Basically, it is a bus of devices, that could act more or less
+   as a complete entity (UCC, USB etc ). All of them should be siblings on
+   the "root" qe node, using the common properties from there.
+   The description below applies to the the qe of MPC8360 and
+   more nodes and properties would be extended in the future.

  *
- *    F flags

- *    S source
- *    P Priority
- *    + node number
- *    * don't care
+ * 00 (0x00 | data) : normal interrupt. data is (class << 4) | source
+ * 01 (0x40 | data) : IO exception. data is the exception number as
+ *                    defined by bit numbers in IIC_SR
+ * 10 (0x80 | data) : IPI. data is the IPI number (obtained from the priority)
+ *                    and node is always 0 (IPIs are per-cpu, their source is
+ *                    not relevant)
+ * 11 (0xc0 | data) : reserved
  *
- * A node consists of a Cell Broadband Engine and an optional
- * south bridge device providing a maximum of 64 IRQs.
- * The south bridge may be connected to either IOIF0
- * or IOIF1.
- * Each SPE is represented as three IRQ lines, one per
- * interrupt class.
- * 16 IRQ numbers are reserved for inter processor
- * interruptions, although these are only used in the
- * range of the first node.
+ * In addition, interrupt number 0x80000000 is defined as always invalid
+ * (that is the node field is expected to never extend to move than 23 bits)
  *
- * This scheme needs 128 IRQ numbers per BIF node ID,
- * which means that with the total of 512 lines
- * available, we can have a maximum of four nodes.
