serial: sh-sci: Fix up SH-2A SCIF support.

2011-11-04T13:33:30+00:00

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.

sh: migrate SH_CLK_MD to mode pin API.

2010-11-09T07:40:00+00:00

This kills off the hardcoded SH_CLK_MD introduced by the SH-2 boards and
converts over to the mode pin API.

sh: Tidy CPU probing and fixup section annotations.

2010-04-21T03:01:06+00:00

This does a detect_cpu_and_cache_system() -> cpu_probe() rename, tidies
up the unused return value, and stuffs it under __cpuinit in preparation
for CPU hotplug.

sh: Kill off timer clock strings for legacy CPG parts.

2010-03-29T08:25:03+00:00

Now with the lookup aliases in place there is no longer any need to
provide the clock string, kill it off for all legacy CPG CPUs.

sh: Kill off all timer name clobbering.

2010-03-10T07:28:16+00:00

Now that dev_name() can be used early, we no longer require a static
string. Kill off all of the superfluous timer names.

sh: Mass ctrl_in/outX to __raw_read/writeX conversion.

2010-01-26T03:58:40+00:00

The old ctrl in/out routines are non-portable and unsuitable for
cross-platform use. While drivers/sh has already been sanitized, there
is still quite a lot of code that is not. This converts the arch/sh/ bits
over, which permits us to flag the routines as deprecated whilst still
building with -Werror for the architecture code, and to ensure that
future users are not added.

sh: Move over to dynamically allocated FPU context.

2010-01-13T03:51:40+00:00

This follows the x86 xstate changes and implements a task_xstate slab
cache that is dynamically sized to match one of hard FP/soft FP/FPU-less.

This also tidies up and consolidates some of the SH-2A/SH-4 FPU
fragmentation. Now fpu state restorers are commonly defined, with the
init_fpu()/fpu_init() mess reworked to follow the x86 convention.
The fpu_init() register initialization has been replaced by xstate setup
followed by writing out to hardware via the standard restore path.

As init_fpu() now performs a slab allocation a secondary lighterweight
restorer is also introduced for the context switch.

In the future the DSP state will be rolled in here, too.

More work remains for math emulation and the SH-5 FPU, which presently
uses its own special (UP-only) interfaces.

sh: sh2a scif pdata (sh7201/sh7203/sh7206/mxg)

2009-12-15T03:06:31+00:00

This patch breaks out the sh2a scif serial port platform
data from a shared platform device to one platform
device per port. Also, add serial ports to the list of
early platform devices.

sh: Apply the sleazy FPU changes for SH-2A FPU as well.

2009-11-24T08:56:17+00:00

This plugs in the fpu_counter manipulation for the SH-2A side also.
