CONFIG_SKIP_RELOCATE_UBOOT
The old way in ARM before ELF relocation was introduced. A misnomer because it seemingly skipped the *COPY* of the image from whereever it was loaded to the TEXT_BASE location. There was no real *RELOCATION* done there. This define probably does not work anymore. It was set on ARM boards where a preloader did load u-boot to the TEXT_BASE address.
In an up to date ARM system all those defines MUST NOT be set.
Thanks for that explanation.
In regard to CONFIG_SKIP_RELOCATE_UBOOT I've hit a typo in arch/arm/cpu/arm926ejs/start.S while trying to use this define to build a non relocatable u-boot. In line 383 there is
ldr pc, r0
which seems to should be
ldr pc, [r0]
But after fixing that I've just run into other problems compiling u-boot with CONFIG_SKIP_RELOCATE_UBOOT defined. I don't send a patch, because I assume that code is just dead will be eliminated in the near future.
