sh: Kill off cf-enabler with extreme prejudice.

2008-12-22T09:44:46+00:00

Now that the rest of the boards that were using cf-enabler "generically"
have switched to setting up their mappings on their own, only the mach-se
boards were left using it. All of the cf-enabler using mach-se boards
use a special initialization of the MRSHPC windows rather than going
through the special PTE as other SH-4 platforms do. This consolidates
the MRSHPC setup logic, hooks it up on the boards that care, and gets rid
of any and all remaining references to cf-enabler.

This has been long overdue, as cf-enabler has been the bane of
arch/sh/kernel for the last 7 years. Good riddance.

sh: Kill off remaining CONFIG_SH_KGDB bits.

2008-12-22T09:44:05+00:00

Now that we use the generic stub, kill off all of the left over
references.

sh: move the hp6xx pm code

2008-12-22T09:43:52+00:00

Move the not-so-generic pm code from arch/sh/kernel/pm.c to the
platform directory together with the rest of the hp6xx pm code.

This is done to let non-hp6xx platforms enable CONFIG_PM.

sh: Only build in gpio.o when CONFIG_GENERIC_GPIO is selected.

2008-10-20T04:04:06+00:00

The pinmux management is tied in to this code, while it is presently only
used by platforms that select GENERIC_GPIO. The asm/gpio.h definitions
are not referenced when GENERIC_GPIO is disabled, resulting in a build
failure for all of the platforms that don't select it.

sh: GPIO and pinmux base code

2008-10-20T01:33:50+00:00

This patch adds gpio code together with the pinmux table parser.
In the future we should optimize this and switch back to gpiolib.

sh: Tidy up ELF core dumps.

2008-09-12T14:27:46+00:00

These have been using overrides for ELF_CORE_COPY_TASK_REGS and
ELF_CORE_COPY_FPREGS while the generic versions can be used instead.
Presently the pt_regs are also duplicated across elf_core_copy_regs()
and elf_core_copy_task_regs(), this switches to simply copying out
through elf_core_copy_regs() instead.

Generic semaphore implementation

2008-04-17T14:42:34+00:00

Semaphores are no longer performance-critical, so a generic C
implementation is better for maintainability, debuggability and
extensibility.  Thanks to Peter Zijlstra for fixing the lockdep
warning.  Thanks to Harvey Harrison for pointing out that the
unlikely() was unnecessary.

sh: trapped io support V2

2008-02-14T05:22:09+00:00

The idea is that we want to get rid of the in/out/readb/writeb callbacks from
the machvec and replace that with simple inline read and write operations to
memory. Fast and simple for most hardware devices (think pci).

Some devices require special treatment though - like 16-bit only CF devices -
so we need to have some method to hook in callbacks.

This patch makes it possible to add a per-device trap generating filter. This
way we can get maximum performance of sane hardware - which doesn't need this
filter - and crappy hardware works but gets punished by a performance hit.

V2 changes things around a bit and replaces io access callbacks with a
simple minimum_bus_width value. In the future we can add stride as well.
