MMIO UART driver on OS

[Zheng Bao]

Hi, All,

I want to add support MMIO UART support on OS.

I checked the file pnp_uart.asl.

For IO UART, a device with EisaId("PNP0501") is added into DSDT, the windows can detect the COM port in device manager.

I am wondering if MMIO UART also have that convinient feature.

Or I need to build a driver for each OS?

Thanks.

Joe
