[U-Boot-Users] [Patch 2/4] U-Boot-V2: ARM: introduceCONFIG_SKIP_RELOCATION

As more and more architectures support booting from just about
anything than a parallel flash, maybe it is better to have a 
CONFIG_COPY_TO_SDRAM than its negative form.

Whats the big benefit of beeing able to select where U-boot runs?
I could understand if there was a need for a compile time parameter.
