Dear Joakim Tjernlund,

Could do what? Modify the memory map such that the Flash is mapped
as it was (eventually) when U-Boot is running, and then jump right in
the middle of nowhere?

That would be invoking undefined behaviour in it's purest form.

Anything can happen then.

Best regards,

Wolfgang Denk
