  • removed non-ASCII characters from FPU comments (neorv32_cpu_cp_fpu.vhd)
  • fixed minor VHDL/GHDL issue (only relevant for older GHDL versions) in PMP mode select (case operand: "object type is not locally static")
  • fixed imprecise timing of first-transmitted UART TX bit (was not correctly synchronized with the UART baud clock)
