This is on our "Envoy" boxes which we have, according to the documentation, an
"Exar ST16C554/554D Quad UART with 16-byte Fifo's". The box also has two
other "on-board" serial ports and a modem chip.
The two on-board serial UARTs were being detected along with the first two
Exar UARTs. The last two Exar UARTs were not showing up and neither was the
modem.
This patch was the only way I could the kernel to see beyond the standard four
serial ports and get all four of the Exar UARTs to show up.

Add a driver for the Xilinx uartlite serial controller used in boards with
the PPC405 core in the Xilinx V2P/V4 fpgas.
The hardware is very simple (baudrate/start/stopbits fixed and no break
support). See the datasheet for details:
http://www.xilinx.com/bvdocs/ipcenter/data_sheet/opb_uartlite.pdf
See http://thread.gmane.org/gmane.linux.serial/1237/ for the email thread.

Allow the 8250 probe modules to be disabled if we're building for
with EMBEDDED enabled. This reduces the kernel size by not including
unnecessary probe module support.
Original idea from Matt Mackall for PCI only, expanded to others by
rmk.

So that it will show up as /dev/ttyS0. Otherwise things like
installers will try to run on whatever serial port gets probed
first.

Since it can do things like BREAK and HUP, we implement
this as a serial uart driver.
This still needs interrupt probing code, as I haven't figured
out how interrupts will work or be probed for on SUN4V yet.

Add driver support for a 2 port PCI IOC3-based serial card on Altix boxes:
This is a re-submission. On the original submission I was asked to
organize the code so that the MIPS ioc3 ethernet and serial parts could be
used with this driver. Stanislaw Skowronek was kind enough to provide the
shim layer for this - thanks Stanislaw. This patch includes the shim layer
and the Altix PCI ioc3 serial driver. The MIPS merged ioc3 ethernet and
serial support is forthcoming.

EPXA10DB seems to be uncared for:
- the "PLD" code has never been merged
- no one has reported that this platform has been broken since
at least 2.6.10
- interest seems to have dried up around March 2003.
Therefore, remove EPXA10DB support.

Add separate files for the different 8250 ISA-based serial boards.
Looking across all the various architectures, it seems reasonable that
we can key the availability of the configuration options for these
beasts to the bus-related symbols (iow, CONFIG_ISA). We also standardise
the base baud/uart clock rate for these boards - I'm sure that isn't
architecture specific, but is solely dependent on the crystal fitted
on the board (which should be the same no matter what type of machine
its fitted into.)

The SGI IOC4 I/O controller chip drivers are currently all configured by
CONFIG_BLK_DEV_SGIIOC4. This is undesirable as not all IOC4 hardware features
are needed by all systems.
This patch adds two configuration variables, CONFIG_SGI_IOC4 for core IOC4
driver support (see patch 1/3 in this series for further explanation) and
CONFIG_SERIAL_SGI_IOC4 to independently enable serial port support.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!
