I'm getting a very confusing error from bitbake. I'm using a snapshot

But, there is such a provider and I can build it (from the same build tree):
$ bitbake virtual/bootloader

After much research, I found that this is happening because I have
MACHINE_EXTRA_RRECOMMENDS="virtual/bootloader
linux-firmware-iwlwifi-5xxx"
If I remove the 'virtual/bootloader' from MACHINE_EXTRA_RRECOMMENDS,
the confusion (and error) go away. Any ideas what's happening and why
I might be getting this confusing error?
The confusion here is between runtime targets (package names, i.e. what you
should specify in MACHINE_EXTRA_RRECOMMENDS) and build-time targets e.g.
virtual/bootloader. virtual/bootloader is not a runtime target (hence "Nothing
RPROVIDES ..." and thus doesn't belong in MACHINE_EXTRA_RRECOMMENDS. I suspect
what you want instead is:
EXTRA_IMAGEDEPENDS += "virtual/bootloader"
Thanks for the explanation, that fixes my problem.
