Shouldn't we provide a CONFIG option by which users can disable Elf relocation?
Why should we? It would just make the code even more complicated, and require a lot of additional test cases.
On production systems you know exactly how much memory you have. Relocation may not be very useful. On the other hand faster boot
is a
bigger concern. Shouldn't we support this case?
If time in your concern, then did you measure the time the relocation costs you? How long is it on your system?
We will do this measurement and get back to you.
Please be aware that a whole number of other features depend on doing real relocation. Also, it brings us a lot closer to use common code
If the preloader loads the u-boot to the location that it is built for everything should work fine once bss is initialized, right?
Best regards, Aneesh
