+ * Encoded IRQs are not considered worth to be supported.
+ * Main reason is that there's no per-encoded-interrupt
+ * enable/disable mechanism (as there was in SH3/4).
+ * An all enabled/all disabled is worth only if there's
+ * a cascaded IC to disable/enable/ack on. Until such
+ * IC is available there's no such support.
+ *
+ * Presumably Encoded IRQs may use extra IRQs beyond 64,
+ * below. Some logic must be added to cope with IRQ_IRL?
+ * in an exclusive way.
+ *
+ * Priorities are set at Platform level, when IRQ_IRL0-3
+ * are set to 0 Encoding is allowed. Otherwise it's not
+ * allowed.
