-/* 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
- * }
