| /* 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 |
| * } |
