I'm open to opinion and sugesstions :)

What you describe above more or less fits the definition of what I 
called the "impedance matcher".  However it doesn't need to be part of 
the kernel at all.  But you should make it into a separate binary.

Please have a look at the bottom of this post for a more comprehensive

Thanks for the link. Interesting read indeed.

The only thing I'm pondering about is that we already have generic
loader code in Linux and a build system that supports a wide range of
platforms. I don't know whether it's worth opening that can of worms
again and re-implement all details about load addresses, compiler flags,
device-tree parsing code yet once again. At least in terms of LOCs, we
would certainly be better off doing it inside the kernel.

But I generally second your opinion about pushing vendors to do it
right, so I might give that approach a shot soon; there is no code yet
anywhere I take it?


Thanks,
Daniel
