Exar-based
With the required refactoring of the code to fit into 8250_exar, we automatically fix the same issue pci_xr17v35x_setup had before: 8XMODE, FCTL, TXTRG and RXTRG were always only set for port 0. Now they are initialized for the correct target port by using port.membase.
My comments below.
