I'm trying to get capsule-on-disk support added to some firmware, and while I can get the CoD via NVRAM method working (where fwupd-efi runs as a boot option) I'm struggling to get the native CoD process working where I'm expecting to be able to see a progress bar as firmware is flashed. At the moment I see OsIndications being set correctly, but I'm missing some driver to handle it.

Should I be using CapsuleOnDiskLoadPei? If so, where is gEdkiiPeiBootInCapsuleOnDiskModePpiGuid supposed to get produced? I don't see any drivers that PRODUCES it - is each platform supposed to implement it?

I'm working on an AArch64 system where I'm pretty sure memory isn't retained between reboots so Capsule-In-Memory won't work.
