I am following the instructions in this link to change the Linux kernel configuration in NITROGEN6X board from Boundary Devices. My question is about exporting the LOADADDR in line 6.

As far as I remember, LOADADDR variable is needed in creating a uImage in 'make uImage' command. But we are not making a uImage here. Where exactly the LOADADDR is being used? More specifically in which make command?
make zImage
make modules
make dtbs
make -C ubuntunize tarball
