Thanks for testing the v3 K1 SPL patchset.
Actually your result confirms the SPL patchset is working correctly and the
build/test procedure is generally complete.

PS: I added some walk through to the key lines in your log below (for you
and for the community's future reference purpose), but for here please be
noted that as I said in the doc patch [1]:

"After DDR init succeeds, SPL proceeds to load U-Boot proper. If
 U-Boot proper is not yet available (as in SPL-only testing), you
 will see SPL: failed to boot from all boot devices - this is
 expected and confirms that SPL with DDR init is working correctly."

Thanks for bringing this up.

Regarding the fsbl.json path: allow me to explain the upstream gitee
repository URL has been redirected from
  https://gitee.com/bianbu-linux/uboot-2022.10
to
  https://gitee.com/spacemit-buildroot/uboot-2022.10

Somehow it causes the fsbl.json path in my doc [1] didn't match.
I will update the repository URL and fix the fsbl.json path in v2 of
the doc patch.

To walk through the key lines:
 "DDR firmware: [...], size:0x8d98" - DDR firmware loaded successfully
 "DDR is ready" - DDR initialization completed
 "SPL: failed to boot from all boot devices" - expected, since no
    storage driver (SPI NOR, MMC, etc.) is included in this patchset
    to load U-Boot proper

Back to the patch series itself, your log is a good validation of
the v3 SPL patchset.

Thank you again for taking the time.
