Yes it also fix the issue, please add by tested-by:

I took this more or less future proof approach because I think this won’t  
be the last chip that needs firmware information, which isn’t available in  
early init, to decides its flags.

Yes it’s intrusive to carve out all flags from early init callbacks, but I  
don’t think it’s that ugly.
