See commit d1cb5eda67a0 ("roms: Add virtual Boot ROM for NPCM7xx SoCs")
for an example adding a ROM file.

Also, we need to be able to rebuild from source the provided vbootrom
blob, which means we need access to the code. I don't see any support
for Aspeed under https://github.com/google/vbootrom. Is that expected ?

What does pc-bios/ast27x0_bootrom.bin contain ?

Thanks,

C.

I have a question regarding the maintenance of the vbootrom submodule. According to the commit log, it was initially added from "google/vbootrom", but the latest version appears to be hosted at https://gitlab.com/qemu-project/vbootrom.git. 
https://github.com/qemu/qemu/blob/master/.gitmodules#L40
I'm currently upstreaming changes from google/vbootrom, which is maintained by Google.
https://github.com/google/vbootrom/pull/5
Should I upstream to the qemu-project/vbootrom repository on GitLab or is it acceptable to continue updating the submodule from google/vbootrom?

Thanks-Jamin
