The second would be trying to "fake" things such that for imx_usb_loader you can pass both SPL and u-boot.img, and SPL is run, inits memory and just exists and then u-boot.img is loaded and run, similar to how with the non-SPL case you can use the loader to pass in u-boot.imx as well as a kernel, ramdisk, etc, into DDR.
I wonder if we could use the i.MX6 ROM "plugin"[1] mechanism with u-boot SPL, to download it through USB, have it configure the DDR and return to the ROM, in a way that would allow us to resume downloading the second stage u-boot through USB...
