* m68knommu: support ColdFire caches that do copyback and write-throughGreg Ungerer2011-01-051-0/+24
| | | | | | | | The version 3 and version 4 ColdFire cache controllers support both write-through and copy-back modes on the data cache. Allow for Kconfig time configuration of this, and set the cache mode appropriately. Signed-off-by: Greg Ungerer <gerg@uclinux.org>
* m68knommu: support version 2 ColdFire split cacheGreg Ungerer2011-01-051-0/+32
| | | | | | | | | | The newer version 2 ColdFire CPU cores support a configurable cache arrangement. The cache memory can be used as all instruction cache, all data cache, or split in half for both instruction and data caching. Support this setup via a Kconfig time menu that allows a kernel builder to choose the arrangement they want to use. Signed-off-by: Greg Ungerer <gerg@uclinux.org>
* m68knommu: make cache push code ColdFire genericGreg Ungerer2011-01-052-1/+49
| | | | | | | | | | | | Currently the code to push cache lines is only available to version 4 cores. Version 3 cores may also need to use this if we support copy- back caches on them. Move this code to make it more generic, and useful for all version ColdFire cores. With this in place we can now have a single cache_flush_all() code path that does all the right things on all version cores. Signed-off-by: Greg Ungerer <gerg@uclinux.org>
* m68knommu: clean up ColdFire cache control codeGreg Ungerer2011-01-051-5/+21
| | | | | | | | | | | | | | | | | | The cache control code for the ColdFire CPU's is a big ugly mess of "#ifdef"ery liberally coated with bit constants. Clean it up. The cache controllers in the various ColdFire parts are actually quite similar. Just differing in some bit flags and options supported. Using the header defines now in place it is pretty easy to factor out the small differences and use common setup and flush/invalidate code. I have preserved the cache setups as they where in the old code (except where obviously wrong - like in the case of the 5249). Following from this it should be easy now to extend the possible setups used on the CACHE controllers that support split cacheing or copy-back or write through options.

* m68knommu: remove do_page_fault(), it is not usedGreg Ungerer2011-01-052-58/+1

* m68knommu: use user stack pointer hardware on some ColdFire coresGreg Ungerer2011-01-052-20/+20
| | | | | | | | | The more modern ColdFire parts (even if based on older version cores) have separate user and supervisor stack pointers (a7 register). Modify the ColdFire CPU setup and exception code to enable and use this on parts that have it. Signed-off-by: Greg Ungerer <gerg@uclinux.org>
* m68knommu: remove command line printing DEBUGGreg Ungerer2011-01-051-5/+0
| | | | | | | | There is no need for the DEBUG based command line printing in here. The kernel will print out the command line in the banner later in the boot up. So remove it. Signed-off-by: Greg Ungerer <gerg@uclinux.org>
* m68knommu: remove fasthandler interrupt codeGreg Ungerer2011-01-051-27/+1

* m68knommu: fix clock rate value reported for ColdFire 54xx partsGreg Ungerer2011-01-051-9/+11
| | | | | | | | | | | The instruction timings of the ColdFire 54xx family parts are different to other version 4 parts (or version 2 or 3 parts for that matter too). Move the instruction timing setting into the ColdFire part specific headers, and set the 54xx value appropriately. Signed-off-by: Greg Ungerer <gerg@uclinux.org>
* m68knommu: move ColdFire CPU names into their headersGreg Ungerer2011-01-051-44/+11
| | | | | | | | | | Move the ColdFire CPU names out of setup.c and into their repsective headers. That way when we add new ones we won't need to modify setup.c any more. Add the missing 548x CPU name. Signed-off-by: Greg Ungerer <gerg@uclinux.org>
* m68knommu: add support for the ColdFire 547x family of processorsGreg Ungerer2011-01-051-1/+6
| | | | | | | | The Freescale M547x family of ColdFire processors is very similar to the M548x series. We use all the same support for it. Initially all we need is a high level configuration option for it. Signed-off-by: Greg Ungerer <gerg@uclinux.org>
* m68knommu: make Coldfire 548x support more genericGreg Ungerer2011-01-055-21/+26
| | | | | | | | | | | | The ColdFire 547x family of processors is very similar to the ColdFire 548x series. Almost all of the support for them is the same. Make the code supporting the 548x more gneric, so it will be capable of supporting both families. For the most part this is a renaming excerise to make the support code more obviously apply to both families. Signed-off-by: Greg Ungerer <gerg@uclinux.org>

In linux/irqflags.h under one configuration, it maps: local_irq_enable() -> raw_local_irq_enable() local_irq_disable() -> raw_local_irq_disable() local_irq_save() -> raw_local_irq_save() ... and under the other configuration, it maps: raw_local_irq_enable() -> local_irq_enable() raw_local_irq_disable() -> local_irq_disable() raw_local_irq_save() -> local_irq_save() ... This is quite confusing. There should be one set of names expected of the arch, and this should be wrapped to give another set of names that are expected by users of this facility. Change this to have the arch provide: flags = arch_local_save_flags() flags = arch_local_irq_save() arch_local_irq_restore(flags) arch_local_irq_disable() arch_local_irq_enable() arch_irqs_disabled_flags(flags) arch_irqs_disabled() arch_safe_halt() Then linux/irqflags.h wraps these to provide: raw_local_save_flags(flags) raw_local_irq_save(flags) raw_local_irq_restore(flags) raw_local_irq_disable() raw_local_irq_enable() raw_irqs_disabled_flags(flags) raw_irqs_disabled() raw_safe_halt() with type checking on the flags 'arguments', and then wraps those to provide: local_save_flags(flags) local_irq_save(flags) local_irq_restore(flags) local_irq_disable() local_irq_enable() irqs_disabled_flags(flags) irqs_disabled() safe_halt() with tracing included if enabled. The arch functions can now all be inline functions rather than some of them having to be macros.

* / | Make do_execve() take a const filename pointerDavid Howells2010-08-182-2/+6
|/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Make do_execve() take a const filename pointer so that kernel_execve() compiles correctly on ARM: arch/arm/kernel/sys_arm.c:88: warning: passing argument 1 of 'do_execve' discards qualifiers from pointer target type This also requires the argv and envp arguments to be consted twice, once for the pointer array and once for the strings the array points to. This is because do_execve() passes a pointer to the filename (now const) to copy_strings_kernel(). A simpler alternative would be to cast the filename pointer in do_execve() when it's passed to copy_strings_kernel(). do_execve() may not change any of the strings it is passed as part of the argv or envp lists as they are some of them in .rodata, so marking these strings as const should be fine. Further kernel_execve() and sys_execve() need to be changed to match. This has been test built on x86_64, frv, arm and mips.
