[U-Boot] U-boot support for Non Console board

Hi , We have a custom board based on coldfire (MCF5484) Similar to MCF5484 Kitlite The board runs Coldfire as PCI agent , 64MB of SDRAM, 4 MB of Bootflash and the PCI bus as a slave (no serial port->no console) I can flash U-boot using the JTAG . Can you let know how can i pass the Commands over PCI . I do not have a Console to do that ?

Please let me know the inputs ?

Thanks and Regards Rajeev S
