serial: Move asm-sh/sci.h to linux/serial_sci.h. This header is needed on other architectures as well (namely h8300), which currently fails to build without this in place. Rather than duplicating the port definition completely there, just move this to a common location instead. This should get h8300 working again for 2.6.25, in addition to the changes already pushed by Sato-san in -rc2. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

Drop support for Renesas H8/300 (h8300) architecture H8/300 has been dead for several years, and the kernel for it has not compiled for ages. Drop support for it.

serial: sh-sci: Abstract register maps. This takes a bit of a sledgehammer to the horribly CPU subtype ifdef-ridden header and abstracts all of the different register layouts in to distinct types which in turn can be overriden on a per-port basis, or permitted to default to the map matching the port type at probe time. In the process this ultimately fixes up inumerable bugs with mismatches on various CPU types (particularly the legacy ones that were obviously broken years ago and no one noticed) and provides a more tightly coupled and consolidated platform for extending and implementing generic features.

serial: sh-sci: Fix up SH-2A SCIF support. This fixes up support for SH-2(A) SCIFs by introducing a new regtype. As expected, it's close to the SH-4A SCIF with fifodata, but still different enough to warrant its own type. Fixes up a number of FIFO overflows and similar for both SH7203/SH7264.

serial: sh-sci: Rework baud rate calculation Computing the baud rate register value requires knowledge of the hardware sampling rate. This information is currently encoded in a baud rate calculation algorithm ID passed through platform data. However, it can be derived from the port type directly in most cases. Compute the sampling rate internally in the driver if the baud rate calculation algorithm ID isn't specified, and allow platforms to override the sampling rate through platform data in special cases (this is only required for SCIFA ports on sh7723 and sh7724, the reason needs to be investigated).
