Display Clock Frequency in U-Boot for LS1043ARDB

How do I display the CPU clock frequencies in U-Boot? CMD_CLK is deprecated and the only other cmd that possibly displays this information is CMD_CPU, however, enabling CMD_CPU causes U-Boot not to build. Is there a command available that I can enable that will display the clock frequencies?

See attached snapshot. This snapshot shows that u-boot reports CPUx clock, Bus clock, DDR clock and FMAN clock on the LS1043a board.

Is additional clock needed to show?
