I looked at Debian and booting Debian kernel with Debian initrd failed:
=> booti ${kernel_addr_r} ${ramdisk_addr_r}:{filesize} ${fdt_addr_r}
Moving Image from 0x7000000 to 0x7080000, end=82f2000
ERROR: RD image overlaps OS image (OS=0x7080000..0x82f2000)
Debian's kernel is big, so it is needed to move also ramdisk_addr_r env
variable. Following patch helped:
diff --git a/include/configs/mvebu_armada-37xx.h b/include/configs/mvebu_armada-37xx.h
