* sh: Build fix for disabled caches.Paul Mundt2009-08-191-2/+0
| | | | | | | | | This fixes up the build when caches are disabled, by linking in all of the cache routines directly. This paves the way for splitting out separate I and D cache disabling, similar to what sh64 had, and which we want for SH-X3 anyways. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: Merge the _32/_64 variants of arch/sh/mm/Makefile.Paul Mundt2009-08-161-4/+66
| | | | | | Now that there is sufficient shared infrastructure, merge the Makefiles. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: Split out extable.c _32 and _64 variants.Paul Mundt2008-01-281-36/+4

* sh: Split out 29-bit and 32-bit physical mode definitions.Paul Mundt2008-01-281-1/+1
| | | | Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: Add -Werror for clean directories.Paul Mundt2007-11-071-0/+2
| | | | | | Follow the MIPS and sparc64 changes for -Werror instrumentation. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: nommu: Kill off dummy page fault ops for SH-3/4.Paul Mundt2007-09-241-2/+0
| | | | | | | | We stopped referencing these functions unconditionally when the old entry.S code was refactored, so this is just dead code at present. Kill it off. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: Fix cache disabling build failures on nommu.Paul Mundt2007-09-211-10/+14
| | | | | | | The cache disabling stuff screwed up some of the sh4 nommu builds, fix it up again. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: Support explicit L1 cache disabling.Paul Mundt2007-09-211-5/+6
| | | | | | | | | This reworks the cache mode configuration in Kconfig, and allows for explicit selection of write-back/write-through/off configurations. All of the cache flushing routines are optimized away for the off case. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: Don't include fault-nommu on SH-2/SH-2A.Paul Mundt2007-08-011-1/+3
| | | | | | | | | | fault-nommu defines the page fault handler stubs for SH-3/4 parts, but is not needed on SH-2/SH-2A now that the entry code has been logically separated. Add it in for SH-3 and SH-4 explicitly. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: Kill off broken dma page ops.Paul Mundt2007-06-111-3/+1
| | | | | | | | There's no point in keeping these around, they've been broken for some time, and the dmaenging/async_tx framework provides a far more reasonable interface. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: Support for multiple nodes.Paul Mundt2007-06-081-0/+1
| | | | | | | | | This adds basic support for multiple nodes on SH machines. This is primarily useful for boards with many different memory blocks that are otherwise unused (SH7722/SH7785 URAM and so forth). Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: Add support for cacheline poking through debugfs.Paul Mundt2006-09-271-0/+4
| | | | | | | A simple debugging aid for easier visibility of the respective cachelines. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: __addr_ok() and other misc nommu fixups.Yoshinori Sato2006-09-271-2/+2
| | | | | | | A few more outstanding nommu fixups.. Signed-off-by: Yoshinori Sato <ysato@users.sourceforge.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: ioremap() overhaul.Paul Mundt2006-09-271-3/+4
| | | | | | | | | | ioremap() overhaul. Add support for transparent PMB mapping, get rid of p3_ioremap(), etc. Also drop ioremap() and iounmap() routines from the machvec, as everyone can use the generic ioremap() API instead. For PCI memory apertures and other special cases, use the pci_iomap() API, as boards are already required to get the mapping right there. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: page table alloc cleanups and page fault optimizations.Paul Mundt2006-09-271-1/+1
| | | | | | | | | | | Cleanup of page table allocators, using generic folded PMD and PUD helpers. TLB flushing operations are moved to a more sensible spot. The page fault handler is also optimized slightly, we no longer waste cycles on IRQ disabling for flushing of the page from the ITLB, since we're already under CLI protection by the initial exception handler.

* sh: SH-4A Privileged Space Mapping Buffer (PMB) support.Paul Mundt2006-09-271-1/+2
| | | | | | | Add support for 32-bit physical addressing through the SH-4A Privileged Space Mapping Buffer (PMB). Signed-off-by: Paul Mundt <lethal@linux-sh.org>

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
