Hi Wolfgang,

I'm just having a hard time letting go of my dream of FDT world 
domination, starting with using a blob to hold the u-boot env variables. :-)

If we ever /do/ have an option to store env variables in a blob, we 
won't need to have (the current) extra code to jam the non-FDT env 
variables into the blob anyway.  ;-)

I don't have any problem removing both the bd_t *and* the env embedding 
"features" since the former is evil and the latter is unused.

Best regards,
