  • 🐛 fixes a bug that permanently stops [m]cycle[h] and [m]instret[h] counter if no HPM counters are implemented (HPM_NUM_CNTS = 0)
  • 🐛 fix bug in WISHBONE.WE signal (when ASYNC_TX mode enabled): signal was high for 1 cycle even if a read transfers (we = low) was triggered (@ Processor wrapper for LiteX integration #350)
  • hardwired dcsr.mprven to 1: mstatus.mprv is also evaluated when in debug mode
  • CFS can now check the current CPU privilege mode (to optionally constrain access/features to privileged software only)
  • minor rtl clean-ups
