Subject: [PATCH v4 0/5] tty/8250: Use fifo in 8250 console driver

This version fixes the bugs reported in version v3. The first patch
is the same patch of v3 as is. The following commits fix the issues in the
original patch. For details, please check the commit log of each patch.

I tested these patches in the following systems:

* IBM X3550 M3
* HP ProLiant DL380 Gen9
* HP ProLiant BL480c G1
* Dell PowerEdge R910
* Cisco UCSC-C220-M3S

I cc everybody that reported problems with the previous version of this
patch so they can retest and confirm their systems work flawlessly.

Wander Lairson Costa (5):
  serial/8250: Use fifo in 8250 console driver
  serial/8250: Use the cache value of the FCR register
  serial/8250: Use tx_loadsz as the transmitter fifo size
  serial/8250: exclude BCM283x from console_fifo_write
  serial/8250: Only use fifo after the port is initialized in
    console_write
