And in the case of the RPi the other enabled SDHCI interface is the WiFi, why would we even be trying to boot off a non storage interface, something here just feels broken/wrong in general. The patch does make it work with pure upstream, and I'm not sure why the Fedora build boots it fine out of the box, but the patch just feels like it's hacking around some other underlying problem with bootstd, we didn't have this problem with the previous method and trying to boot off non storage interfaces feels like it could cause other problems.
