intList has been populated with the number of isrs, aka interrupts, but nothing has not been using this information so we drop it and everything used to construct it. Signed-off-by: Sebastian Bøe <sebastian.boe@nordicsemi.no>

/* 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
|
|
* }
