DM8148 GPMC_FCLK value

Dear all,

I dump the related GPMC_CONFIG* registers to know the corresponding values as below on DM8148EVM.

1. CSONTIME = 0 GPMC_FCLK cycle  / CSRDOFFTIME = 4 GPMC_FCLK cycle / CSWROFFTIME = 4 GPMC_FCLK cycle

2. OEONTIME = 1 GPMC_FCLK cycle / OEOFFTIME = 5 GPMC_FCLK cycle

3. WEONTIME = 1 GPMC_FCLK cycle / WEOFFTIME = 3 GPMC_FCLK cycle

How do I know the GPMC_FCLK value? Because it is an internal clock, acts as the time reference. Please give some hints to calculate the GPMC_FCLK. Thanks in advance.

B.R.
