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.

Regards,

Alexander
