Hi Zong,
According to Bin Meng's patch "azure/gitlab: Add tests for SiFive
Unleashed board," the script currently uses the "genimage" tool.

However, if we want to switch to using "binman," I am unsure if it
would be a meaningful change. Perhaps Bin Meng could offer some help
on this?

Hi Bin Meng,
Do you have any ideas regarding this issue?
