ROM should find the GP header at offset 0 and load/execute SPL. SPL -then detects that ROM was in QSPI-1 mode (boot code 10) and attempts to -find a U-Boot image header at offset 0x20000 (set in the config file) -and proceeds to load that image using the U-Boot image payload offset/size -from the header.
