Currently u-boot supports addresses upto 39-bits only. If anybody wants to use addresses of more than 39-bits in Linux they will have a separate memory node in DT. In such cases they will have multiple memory nodes. Currently u-boot selects and runs on lower memory bank region. But bootscript is being loaded on dram bank 0, where dram bank 0 will point to 1st memory node in DT. If first memory node is mentioned as higher ddr(>39-bits address) then u-boot cannot load the bootscript. So fix this issue by setting bootscript address within the lower memory bank region.
