I'm a little confused about what you mean by "newer firmware." Do you 
mean >= 017a5aea or > 017a5aea?

Because in your last email you mentioned you discovered the problem 
starting with b379b067.

The firmware's tree log is as follows:

https://github.com/sophgo/edk2-non-osi/commits/devel-sg2042/

latest commit

.

017a5aea <---- dma-coherenet patch was submitted together with this commit.
