Is this the code that handles USB boot? #206

Sorry in advance if this question is moot (I did search for it, but no luck). Is this the layer that determines what hardware are compatible with booting from USB-only (versus from mmcblk0)? Or is that handled at a layer below this? If it's not this code, plz close this issue with my apologies for cluttering the issues list momentarily. If this code does handle USB boot, how can one provide assistance to increase the number of hubs and devices with which USB boot is compatible?

If you are talking about booting without an SD card in the Pi then the code in question is in the ROM, meaning it can't be changed.
