  nozomi: Add tty_port usage
  sdio_uart: Use kfifo instead of the messy circ stuff
  serial: bcm63xx_uart: allow more than one uart to be registered.
  serial: bcm63xx_uart: don't use kfree() on non kmalloced area.
  serial: bfin_5xx: pull in linux/io.h for ioremap prototypes
  serial: bfin_5xx: kgdboc should accept gdb break only when it is active
  serial: bfin_5xx: need to disable DMA TX interrupt too
  serial: bfin_5xx: remove useless gpio handling with hard flow control
