elf file loading to 64bit address in uboot

[m_kei]

Using lx2160ardb_rev2.

I would like to load an elf file placed on the SD card in u-boot onto DRAM Region #2.
Since DRAM Region #2 resides on 0x2080000000-0x3FFFFFFFFFFFF, it must be specified with a 64-bit address.

When I try to do this with the ext4load command, I get the following error and it fails.

"Cannot use 64 bit addresses with SDMA"

What should I do about this?
Is there any other way to place elf files in DRAM Region #2?

You could use the following method.

=> load mmc 0:1 0xa0000000 Image
=> cp.b 0xa0000000 0x2080000000 $filesize
