Hello.[Resending to the list as I've only replied to Andrei -- due to stupid keyboard layout switcher in OpenSUSE preventing Ctrl-Shift-R in Thunderbird from working... :-/]

I studied this driver and few other examples and I have one question regarding the driver configuration: Which field must be initialized in the plat_serial8250_port structure: unsigned long iobase; /* io base address */ void __iomem *membase; /* ioremap cookie or NULL */ resource_size_t mapbase; /* resource base */ Some drivers init only one of them, other two fields.
Of course, .iobase is for I/O port mapped UARTs (think PC), .mapbase and .membase are for the memory mapped UARTs (like your case).
My UART is located at 0x1bf01000, can I put this value in all those fields?
You only need to put that into ,mapbase.
