  • add a programmable interrupt to the TRNG (based on the entropy FIFO's fill level); mapped to CPU's fast interrupt request channel 15; allows the CPU to be notified when a certain "amount" of entropy is available
  • ⚠️ remove IS_SIMULATION flag from SYSINFO (redundant, as the same flag is also present in the CPU's mxisa CSR)
