Dear Joakim Tjernlund,

But why has the GOT table to fit "into built-in CPU memory"? When we are about to relocate U-Boot to RAM, we already have RAM working. So we should also be able to copy the GOT table to RAM and modify it there as needed before we use it?
Before you get RAM working there are lots of references to global data and string literals. These point to their link address so if you have loaded u-boot at a different address than you link address you have to adjust for the offset. Hard to do that when GOT is in flash :(
Ah, I finally GOT you :-)
Hm... but being able to load (and start) U-Boot from an arbitrary RAM location would be a big benefit, too, even if we still have to copy it to the correct (linked) address when storing it in flash.
