The drivers/tty/serial dir is already getting rather busy. Relocate the 8250 related drivers to their own subdir to reduce the clutter. Note that sunsu.c is not included in this move -- it is 8250-like hardware, but it does not use any of the existing infrastructure -- and does not depend on SERIAL_8250.

With reset port, set clock and get clock functions in SoC specific extentions being removed, only the driver probe is left over in these extensions. The probe function itself can be merged into one and moved into the samsung common serial driver. With driver probe also moved, all the SoC specific extentions are no longer required and they are deleted.

The recent commit "serial: add irq handler for Freescale 16550 errata" would allow Kconfig choices that had 8250 support as a module and yet still try and build in the errata fix non-modular, resulting in build failures for some non-embedded PPC targets. Since we hook in the errata fix from legacy_serial.c, which is built only for PPC_UDBG_16550, and since the errata is only really relevant for SysRQ on serial console, tighten up the dependencies to be exactly that. We'll get coverage on the relevant Freescale boards because the Kconfig for their CPU types all select the PPC_UDBG_16550 option, and the defconfigs also all select the 8250_CONSOLE option. Also, the 8250_CONSOLE option has a strict dependency on "SERIAL_8250=y" which resolves the reported problem for non Freescale targets.

Sending a break on the SOC UARTs found in some MPC83xx/85xx/86xx chips seems to cause a short lived IRQ storm (/proc/interrupts typically shows somewhere between 300 and 1500 events). Unfortunately this renders SysRQ over the serial console completely inoperable. The suggested workaround in the errata is to read the Rx register, wait one character period, and then read the Rx register again. We achieve this by tracking the old LSR value, and on the subsequent interrupt event after a break, we don't read LSR, instead we just read the RBR again and return immediately. The "fsl,ns16550" is used in the compatible field of the serial device to mark UARTs known to have this issue. Thanks to Scott Wood for providing the errata data which led to a much cleaner fix.

The driver was originally developed by Google. It is functionally equivalent to the version available at: http://android.git.kernel.org/?p=kernel/experimental.git the differences being: 1) Remove wakelocks and change unsupported DMA API. 2) Replace clock selection register codes by macros. 3) Fix checkpatch errors and add inline documentation. 4) Add runtime PM hooks for active power state transitions. 5) Handle error path and cleanup resources if required.

Rather than maintain Kconfig entries where people have to enter raw numbers and hardcode lists of addresses/pins in the driver itself, push it all to platform resources. This lets us simplify the driver, the Kconfig, and gives board porters greater flexibility. In the process, we need to also start supporting the early platform interface. Not a big deal, but it causes the patch to be bigger than a simple resource relocation. All the Blackfin boards already have their resources updated and in place for this change.
