Is there a reason we can't also get these from the environment? Or a limitation of (how we support) the simulator that we don't have persistent r/w environment right now?
These names can also come from the environment, there's r/w capability there, just no physical eMMC. Thanks.
I need to play more with the foundation model then, I didn't think we could talk with the "mmc" or anything on it. As you've got it coded now, you can't change what's loaded here :) But if we can have a file-backed storage used as the "disk" and keep env there, making this load files named in the environment and then fw_getenv/setenv can change the values from Linux too, if we don't boot into a full U-Boot at some point.
