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.
