+/* This creates a special section which is not included by the final binary,
+ * instead it is consumed by the gen_isr_tables.py script.
+ *
+ * What we create here is a data structure:
+ *
+ * struct {
+ *	u32_t num_vectors;       <- typically CONFIG_NUM_IRQS
+ *	struct _isr_list isrs[]; <- Usually of smaller size than num_vectors
+ * }
+ *
+ * Which indicates the memory address of the number of isrs that were
+ * defined, the total number of IRQ lines in the system, followed by
+ * an appropriate number of instances of struct _isr_list. See
+ * include/sw_isr_table.h
+ *
+ * You will need to declare a bogus memory region for IDT_LIST. It doesn't
+ * matter where this region goes as it is stripped from the final ELF image.
+ * The address doesn't even have to be valid on the target. However, it
+ * shouldn't overlap any other regions. On most arches the following should be
+ * fine:
+ *
+ * MEMORY {
+ *	.. other regions ..
+ *	IDT_LIST        : ORIGIN = 0xfffff7ff, LENGTH = 2K
+ * }
