The actual frequencies in /sys/kernel/debug/clk/clk_summary are correct, though,
considering MD14=MD13=MD19=M17=1 (for a 33.3333 MHz EXTAL), while
Salvator-X has a 16.6666 MHz EXTAL.
Perhaps you missed the extal divider?
Note that I have measured MSIOF clock signal frequencies before, and they
matched Linux' point of view.
