[U-Boot] [RFC PATCH] arm: provide a CONFIG flag for disabling relocation

This is plain wrong.  This has been explained a couple of times
before.  Please read the archives.

Do you have numbers?  How much delay do you see caused by the
relocation of U-Boot?

You appear not to understand what relocation is needed for.


I tend to reject your patch, unless you can come up with really
convincing arguments. Also, your patch should then work for all
boards - not only ARM, but also PowerPC (one of the arguments for
relocation was that we want to unify the code).


Best regards,

Wolfgang Denk
