The USB boot code is too fat and complicated to be included in SPL (at least for now). So, it was implemented as a separate project (what we call USB-loader). The expected boot sequence is as follows: Boot ROM -> USB-loader -> SPL -> U-Boot proper The USB-loader loads the SPL and U-Boot proper from a USB memory onto the locked L2 cache. Then, SPL needs to copy the U-Boot proper to DRAM, so this mode looks like a NOR boot from the view of SPL. However, we want to distinguish between (genuine) NOR boot and USB boot in some places.
