Hi Marek,

We already do it on ARM though and the reason for this is to place U-Boot at the end of the DRAM, so that most of the DRAM can be used by the user.
We place U-Boot at the end of the DRAM on nios2, too. :)
I will look into the relocation on nios2 next time. But for now, I would suggest that we skip this and move on to driver model.
These two things are orthogonal, so no problem :)
In fact, I am loading U-Boot with GDB thus far, so I am only copying it once ;-) Where is the second copying coming from ?
That was true for gdb. But when you need to try out u-boot-dtb.bin on EPCS/sf, it will be another story..
Why so? The EPCS is memory mapped and U-Boot starts from it, right ? So U-Boot can relocate itself to the end of DRAM , right ?
