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
