This is a little tricky since SoCFPGA has code to determine this as runtime. Introduce a guard variable for platforms to select if they have a static value to use. Then for ARCH_SOCFPGA, call cm_get_qspi_controller_clk_hz() and otherwise continue the previous behavior. Cc: Jagan Teki <jagan@amarulasolutions.com> Signed-off-by: Tom Rini <trini@konsulko.com>
