sg2042-dmesg.txt

During working on sbi upstream, we find a werid crash issue, details as below:

With opensbi branch "issue-23" + linux branch "issue-23", system could not boot-up and error log see:
log-failed.txt

But with opensbi branch "milkv-pioneer-minmal" + linux branch "sophgo", system can boot up well.

We doubt the failure is related to the new opensbi, because opensbi branch "issue-23" is based on latest opensbi master （v1.3+), but opensbi branch "milkv-pioneer-minmal" is still based off v1.2.

This heavily blocks upstream work for sg2042. Need more help and input to help push it forward.
