The code in the AMD-Xilinx platform for Versal and Versal NET is being refactored to move the plat_get_syscnt_freq2() function to a common file. This common function is utilized for obtaining the CPU clock frequency from the platform. Change-Id: I7a4c3fa43a2941d51cacd259c57b24e545aea848 Signed-off-by: Prasad Kummari <prasad.kummari@amd.com>
