You don't need to define uart_address. A uart doesn't need an address, right? The addresses are from the processor. A peripheral to a processor needs an address.

So we have double whammy here :). Question: There are address lines coming from a processor but our peripheral/device has no port which looks like an address line. What do we do? Answer: Use some enable signal like chip_select or tx_enable which kicks off the peripheral to work as an equivalent to an address line.
