I have not tried this yet, but it looks like it should be possible to 
set up with the jailhouse-cell-linux tool using the "--initrd" option. 
Is this correct? What is the expected image format of the ramfs (e.g. 
*.cpio.gz)?

There may be some technical challenges to work through as I am not aware 
of a method to include one rootfs image inside of another rootfs image. 
Denys, do you know if this is possible?

Sure. Hopefully we can get a common set of args between j7-evm and am65xx.
