zcu102 boot "SF: unrecognized JEDEC id bytes: 00, 00, 00"

Describe the bug

Hi, I want to boot the original labeled RISC-V on the zcu102 board, but after following the steps in the README, I get the following u-boot error:

SF: unrecognized JEDEC id bytes: 00, 00, 00
Failed to initialize SPI flash at 0:0 (error -2)
SCRIPT FAILED: continuing...
starting USB...
USB0: "Synchronous Abort" handler, esr 0x96000210

To Reproduce
By following all steps in fpga/README.md and fpga/boot/README.md. I already applied the zcu102 patch.

Expected behavior
I can successfully emulate with verilator. And I used another pre-build image to boot the zcu102 board, it works well. In the pre-built u-boot image, I can check the flash model info.

ZynqMP> sf probe
SF: Detected n25q512a with page size 512 Bytes, erase size 128 KiB, total 128 MiB

So I think it is not a hardware problem.
