Ok these are all mainline now, but I'm needing some deps to get this
applied to v3.19.

Patch 48c0615, seems to require ed59190e, which in turn probably needs
d800ba1 (plus I'm not sure what.) Since there are large amount of
change, I'd like to see what you suggest should be backported as well to
make the first patch a cleaner change. Removing opal_flash_init without
ed59190e seems dangerous, but since I'm not an expert here I'd like to
get your strategy for applying this to v3.19.
