2006-09-27sh: Fix occasional flush_cache_4096() stack corruption.Paul Mundt
IRQs disabling in flush_cache_4096 for cache purge. Under certain workloads we would get an IRQ in the middle of a purge operation, and the cachelines would remain in an inconsistent state, leading to occasional stack corruption. Signed-off-by: Takeo Takahashi <takahashi.takeo@renesas.com> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2006-09-27sh: Calculate shm alignment at runtime.Paul Mundt
Set the SHM alignment at runtime, based off of probed cache desc. Optimize get_unmapped_area() to only colour align shared mappings. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2006-09-27sh: Initial vsyscall page support.Paul Mundt
This implements initial support for the vsyscall page on SH. At the moment we leave it configurable due to having nommu to support from the same code base. We hook it up for the signal trampoline return at present, with more to be added later, once uClibc catches up. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2006-09-27sh: Selective flush_cache_mm() flushing.Paul Mundt
flush_cache_mm() wraps in to flush_cache_all(), which is rather excessive given that the number of PTEs within the specified context are generally quite low. Optimize for walking the mm's VMA list and selectively flushing the VMA ranges from the dcache. Invalidate the icache only if a VMA sets VM_EXEC. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2006-09-27sh: More intelligent entry_mask/way_size calculation.Paul Mundt
Figure out the cache desc entry_mask at runtime, and remove hard-coded assumption about the cacheline size. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2006-09-27sh: Support for L2 cache on newer SH-4A CPUs.Paul Mundt
This implements preliminary support for the L2 caches found on newer SH-4A CPUs. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

2006-09-27sh: Add support for 4K stacks.Paul Mundt
This enables support for 4K stacks on SH. Currently this depends on DEBUG_KERNEL, but likely all boards will switch to this as the default in the future. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2006-09-27sh: Enable /proc/kcore support.Paul Mundt
This was previously unimplemented.. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

2006-09-27sh: select CONFIG_EMBEDDED.Paul Mundt
This solution isn't very optimal, but it's generaly the behaviour that we want.. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2006-09-27sh: machvec rework.Paul Mundt
Some more machvec overhauling and setup code cleanup. Kill off get_system_type() and platform_setup(), we can do these both through the machvec. While we're add it, kill off more useless mach.c's and drop some legacy cruft from setup.c. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2006-09-27sh: Solution Engine SH7343 board support.Paul Mundt

2006-09-27sh: Cleanup IRQ disabling for hardirq handlers.Paul Mundt
The generic hardirq layer already takes care of a lot of the appropriate locking and disabling for us, no need to duplicate it in the handlers.. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2006-09-27sh: maskreg IRQ support.Paul Mundt
Formerly implemented by ADX, we can use this generically, so move it over. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2006-09-27sh: Kill off dead boards.Paul Mundt
None of these have been maintained in years, and no one seems to be interested in doing so, so just get rid of them. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2006-09-27sh: Add support for cacheline poking through debugfs.Paul Mundt
A simple debugging aid for easier visibility of the respective cachelines. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

This fixes up some of the various outstanding nommu bugs on SH. Signed-off-by: Yoshinori Sato <ysato@users.sourceforge.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2006-09-27sh: Make PAGE_OFFSET configurable.Paul Mundt
nommu needs to be able to shift PAGE_OFFSET, so we switch it to a non-user-visible CONFIG_PAGE_OFFSET and use that in the few places where it matters. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2006-09-27sh: Move voyagergx_reg.h to a more sensible place.Paul Mundt
Other boards require this as well, so move it out of the rts7751r2d directory. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2006-09-27sh: math-emu supportTakashi YOSHII
This implements initial math-emu support, aimed primarily at SH-3. Signed-off-by: Takashi YOSHII <takasi-y@ops.dti.ne.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2006-09-27sh: Rename rtc_get/set_time() to avoid RTC_CLASS conflict.Paul Mundt
We have a clash with RTC_CLASS over these names, so we change them.. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2006-09-27sh: Fixup __strnlen_user() behaviour.Paul Mundt
Drop TIF_USERSPACE and add addr_limit to the thread_info struct. Subsequently, use that for address checking in strnlen_user() to ward off bogus -EFAULTs. Make __strnlen_user() return 0 on exception, rather than -EFAULT. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2006-09-27sh: More cosmetic cleanups and trivial fixes.Paul Mundt
Nothing exciting here, just trivial fixes.. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2006-09-27sh: Fixup TEI IRQ requests in request_dma().Paul Mundt
If a channel is not TEI capable, don't try to request_irq().. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2006-09-27sh: G2 DMA IRQ and residue sampling.Paul Mundt
This fixes a long-standing FIXME for G2 DMA, where we finally wire up the IRQ handler and allow for sampling remaining bytes while in-flight. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2006-09-27sh: VoyagerGX cleanups and 8250 UART support.Paul Mundt
This adds the VoyagerGX UART to the RTS7751R2D setup code, and cleans up a few build issues. Signed-off-by: Manuel Lauss <mano@roarinelk.homelinux.net> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2006-09-27sh: Inhibit mapping PCI apertures through page tables.Paul Mundt
Inhibit mapping through page tables in __ioremap() for PCI memory apertures on SH7751 and SH7780-style PCI controllers, translation is not possible for these areas. For other users that map a small window in P1/P2 space, ioremap() traps that already, and should never make it to __ioremap(). Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2006-09-27sh: Consolidated SH7751/SH7780 PCI support.Paul Mundt
This cleans up quite a lot of the PCI mess that we currently have, and attempts to consolidate the duplication in the SH7780 and SH7751 PCI controllers. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2006-09-27sh: kgdb stub cleanups.Paul Mundt
Some kgdb cleanup. Move hexchars/highhex/lowhex to the header, so it can be reused by sh-sci. Also drop silly ctrl_inl/outl() overloading being done by the kgdb stub. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2006-09-27sh: Use generic CONFIG_FRAME_POINTER.Paul Mundt
We had our own version, which serves no purpose. Simply hook SH in to the generic one. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2006-09-27sh: APM/PM support.Andriy Skulysh
This adds some simple PM stubs and the basic APM interfaces, primarily for use by hp6xx, where the existing userland expects it. Signed-off-by: Andriy Skulysh <askulysh@gmail.com> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2006-09-27sh: SE73180 updates for IRQ changes.Paul Mundt
SE73180 can use the generic support, we just need to wire up the IRQ demuxing. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2006-09-27sh: Make O= builds work again.Paul Mundt
Some of the paths were a bit broken, fix it up. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
