  • source out trigger module into a dedicated HDL file (neorv32_cpu_hwtrig.vhd)
  • rework entire trigger module logic
  • fix trigger enumeration (in previous versions an unlimited number of HW triggers might have been reported by openOCD)
  • simplify trap-to-debug-mode logic
  • add support for "hardware-assisted data watchpoints" (via GDB's [a|r]watch)
