/* 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
* }
