To boot S-mode firmware payload like EDK2 from persistent flash storage, qemu needs to pass the flash address as the next_addr in fw_dynamic_info to the opensbi. When both -kernel and -pflash options are provided in command line, the kernel (and initrd if -initrd) will be copied to fw_cfg table. The S-mode FW will load the kernel/initrd from fw_cfg table. If only pflash is given but not -kernel, then it is the job of of the S-mode firmware to locate and load the kernel. In either case, update the kernel_entry with the flash address so that the opensbi can jump to the entry point of the S-mode firmware.
