Hi,

We have several use cases where customers want to partition memory by
putting NS images above 4GB. On Xilinx arm 64bit SOC 0-2GB can be used for
others CPU in the systems (like R5) or for secure sw.
Currently there is limitation in SPL to record load/entry addresses in
64bit format because they are recorded in 32bit only.
This series add support for it.
Patches have been tested on Xilinx ZynqMP zcu102 board in SD bootmode with
images generated by binman. Because u-boot is using
CONFIG_POSITION_INDEPENDENT it can be put to others 4k aligned addresses
and there is no real need to build it to certain offset.

Thanks,
Michal
