Both software emulated and hardware based CTS and RTS are enabled in

The CTS RTS PIN connection on BF548 UART port is defined as a modem

Add support for the nwp serial device which is connected to a DCR bus. It
uses the of_serial device driver to determine necessary properties from
the device tree. The supported device is added as serial port number 85.
NWP stands for network processor and it is part of the QPACE - Quantum
Chromodynamics Parallel Computing on the Cell Broadband Engine project.
The implementation is a lightweight uart implementation with the focus
to consume as little resources as possible and it is connected to a
DCR bus.

Manual fixup of conflicts on:
arch/powerpc/include/asm/dcr-regs.h
drivers/net/ibm_newemac/core.h

This requires three changes:
1) Remove !SPARC restriction in Kconfig.
2) Move Sparc specific serial drivers before 8250, so that serial
console devices don't change names on us, even if 8250 finds
devices.
3) Since the Sparc specific serial drivers try to use the
same major/minor device namespace as 8250, some coordination
is necessary. Use the sunserial_*() layer routines to allocate
minor number space within TTY_MAJOR when CONFIG_SPARC.
This has no effect on other platforms.
Thanks to Josip Rodin for bringing up this issue and testing
plus debugging various revisions of this patch.

Trying to compile the v850 port brings many compile errors, one of them exists
since at least kernel 2.6.19.
There also seems to be noone willing to bring this port back into a usable
state.
This patch therefore removes the v850 port.
If anyone ever decides to revive the v850 port the code will still be
available from older kernels, and it wouldn't be impossible for the port to
reenter the kernel if it would become actively maintained again.

The S3C2410 serial driver in drivers/serial/s3c2410.c has been
growing bigger with the addition of more variants of this hardware
with the growing Samsung SoCs range. As such, it would be
easier to split this code up into a core and per-cpu drivers to
make driver addition easier, and the core smaller.

This patch is based on the DMA-patch by Chip Coldwell for the AT91/AT32 serial
USARTS, with some tweaks to make it apply neatly on top of the other patches
in this series.
The RX and TX code has been moved to a tasklet and reworked a bit. Instead of
depending on the ENDRX and TIMEOUT bits in CSR, we simply grab as much data as
we can from the DMA buffers. I think this closes a race where the ENDRX bit
is set after we read CSR but before we read RPR, although I haven't confirmed
this.
Similarly, the two TX handlers (ENDTX and TXBUFE) have been combined into one.
Since the current code only uses a single TX buffer, there's no point in
handling those interrupts separately.
This also fixes a DMA sync bug in the original patch.

Reformat the Kconfig entries and update descriptions for accuracy. Select the
driver by default for configurations of interest. For the curious: 32BIT
means only 32-bit DECstations support the device, not that the driver is not
64-bit clean; I have not checked that either though.
