When needed, RPi4's co-processor (called VideoCore) has to be instructed to load VL805's firmware (the chip providing xHCI support). VideoCore's firmware expects the board's PCIe bus to be already configured in order for it to load the xHCI chip firmware. So we have to make sure this happens in bet
