What's the primary motivation for full relocation? I found
The fundamental problems of the ARM implementation (and others, like MIPS etc.) have been discussed here on the list many times before. > a Wiki page (below), is this the one? > > http://elinux.org/CELF_Project_Proposal/Rework_ARM_architecture_support_in_U-Boot Yes, this is the one. Actually all these commits were supposed to include this message: Portions of this work were supported by funding from the CE Linux Forum. Unfortunately it seems Heiko has forgotten to add this to the commit messages; I'll ping him again. If you read the thread you can see that both Heikos tests and other testers who tried that code see dramatic speed improvements due to enabling the cache; in addition to that we win all the flexibility of RAM usage we are used to from other architectures. So the last big remaining thing that needs to be added is to add device tree support and get rid of these stupid ATAGs and MACHIDs. Fortunately work on this front in on the way as well.
