[PATCH 2/3] bsps/irq: Remove BSP_INTERRUPT_VECTOR_MIN

Sebastian Huber sebastian.huber at embedded-brains.de
Fri Jun 18 07:20:34 UTC 2021


This define was defined to be zero for all BSP except:

* or1k/generic_or1k which has only an incomplete implementation.

* m68k/genmcf548x which is a special case.  This BSP uses a custom
  implementation for libbsd compatibility.  This custom implementation didn't
  use BSP_INTERRUPT_VECTOR_MIN.

The BSP_INTERRUPT_VECTOR_MIN == 0 condition was tested by a temporary static
assertion and building all BSPs.

Update #3269.
