UART: add CSR SiRFprimaII SoC on-chip uart drivers 



SiRFprimaII is the latest generation application processor from CSR’s
multi-function SoC product family.
The SoC support codes are in arch/arm/mach-prima2 from Linux mainline
3.0.

There are three dedicated UARTs in system. This patch adds basic driver
support for them.

It has used the newest pinmux subsystem from Linus Walleij.

          providing /dev/ttySiRF0, 1 and 2 (note, some machines may not

          Even if you say Y here, the currently visible virtual console

          (/dev/tty0) will still be used as the system console by default, but

          you can alter that using a kernel command line option such as

          "console=ttySiRFx". (Try "man bootparam" or see the documentation of

          your boot loader about how to pass options to the kernel at

          boot time.)
