An abstraction of that from the specifics of the PC's serial port might be nice, yes. (omap_uart.c has to jump through some ugly hoops currently, with more ugliness in the out-of-tree omap3 extensions.) However I don't think it makes sense to force all serial port device models to go through it -- not all the world is a 16550A and some UARTs simply are different. thanks -- PMM
