Hi, the changes look good to me. I don't think I can include the new bootcode 
since I have no idea what effect it would have on older devices. Since you 
say the older code works as well for you, I'd be tempted to just leave that 
as it is. Unless someone else knows the difference?

I'll need your signed-off-by line to include it into the tree though.
