UART on Quark platfor, according to Quark BSP Programmer's Reference Manual, is located in the following order on PCI bus: COM2 BAR0: 16550 registers BAR1: DMA registers COM1 BAR0: 16550 registers BAR1: DMA registers So, the driver on Quark platform has to specify BAR (Base Address Registers) number, the pci_bus_scan() function looks for. As long as UART is a concole device, calling pci_show() during it's initialization does not make any output.
