For QSPI boot and SD boot with QSPI, we could only read from FPGA through I2C to get the system clock and DDR clock info. However in U-Boot booting flow, I2C is not initialized when get_clocks() is called and thus it couldn't get correct value of the clocks. So the configuarable clock is only supported by non-QSPI boot.

Qianyu,
Please work with Yuan Yao on qixis access. We may have a solution to get the clocks on QSPI boot.
