How to create handoff information for bootloader and preloader without FPGA

For software development would like to be able to create handoff files (iocsr, pinmux config, pllconfig) without having to synthesize an FPGA. Applying in the HPS configuration is a tedious process. Is this possible ? And why are those files not generated by QSYS and need I to create and FPGA (which I will not use) to configure the CPU.

Thanks in advance,
