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
