* sh: Fix up breakage from asm-generic/pgtable.h changes.Paul Mundt2011-01-141-0/+1

* sh: sh7372 SH4AL-DSP probe supportMagnus Damm2011-01-131-1/+1
| | | | | | | | | | | | | Add probe support for the sh7372 SH4AL-DSP core. The most common use case for this is when the system boots from the ARM core in the sh7372 and uses the SH core for application offload as a slave CPU. May also be used to boot the sh7372 from the SH core. Signed-off-by: Magnus Damm <damm@opensource.se> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: Fix up legacy PTEA space attribute mapping.Paul Mundt2011-01-112-2/+15
| | | | | | | | | | | | | When p3_ioremap() was converted to ioremap_prot() there was some breakage introduced where the 29-bit segmentation logic would trap the area range and return an identity mapping without having allowed the area specification to force mapping through page tables. This wires up a PCC mask for pgprot verification to work out whether to short-circuit the identity mapping on legacy parts, restoring the previous behaviour.

* sh: Stub out legacy PCC pgprot encoding for X2 TLBs.Paul Mundt2011-01-111-7/+1Star
| | | | | | | | | Presently it's still possible to reference the PAGE_KERNEL_PCC pgprot encoding on X2 TLBs which simply don't support it at all. Convert this over to follow the nommu behaviour and simply hand back an invalid pgprot value so we error out properly. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

In order to support this sort of use it's necessary to get out of the way with regards to namespace collisions, and at the same time we can also kill off some duplicate code now that the unaligned headers are a bit more broken out.

This patch changes the meaning of PG_arch_1 to be PG_dcache_clean and always flush the D-cache for a newly mapped page in update_mmu_cache(). This addresses issues seen with executing binaries from MMC, in addition to some of the other HCDs that don't explicitly do cache management for their pipe-in buffers.

So this patch is to use it for implementing the prefetch on SH2A and SH4. The current prefetch implementation is almost equivalent with __builtin_prefetch. The third parameter in the __builtin_prefetch is the locality that it's not supported on SH architectures. It has been set to three and it should be verified if it's suitable for SH2A as well. I didn't test on this architecture. The builtin usage should be more efficient that an __asm__ because less barriers, and because the compiler doesn't see the inst as a "black box" allowing better code generation. This has been already done on other architectures (see the commit: 0453fb3c528c5eb3483441a466b24a4cb409eec5). Many thanks to Christian Bruel <christain.bruel@st.com> for his support on evaluate the impact of the gcc built-in on SH4 arch. No regressions found while testing with LMbench on STLinux targets.

| |/ | | | | | | | | | | | | | | | | | | | | | | | | This takes a bit of a sledgehammer to the machvec I/O routines. The iomem case requires no special casing and so can just be dropped outright. This only leaves the ioport casing for PCI and SuperIO mangling. With the SuperIO case going through the standard ioport mapping, it's possible to replace everything with generic routines. With this done the standard I/O routines are tidied up and NO_IOPORT now gets default-enabled for the vast majority of boards. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When CONFIG_PMB enable, ITLB is not cleared by reset of watchdog timer. This should use trigger_address_error(). Signed-off-by: Nobuhiro Iwamatsu <nobuhiro.iwamatsu.yj@renesas.com> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
| * | | sh: Provide a global TLB flush for U/I-TLB clear.Paul Mundt2010-07-021-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This provides a sledgehammer approach for clearing the TLBs, only to be used in cases where we know we will never want to use the mappings again and have no interest in preserving state. This also destroys wired entries. The primary use for this is when we are either entering or exiting the kernel completely, in the latter case as a precursor for CPU reset by MMU.

| * | | sh: fix up an off-by-1 in the number of early ioremap fixmaps.Paul Mundt2010-06-211-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There was an off-by-1 in the begin/end of the ioremap fixmaps, leaving us with a spurious entry. In practice this wasn't a problem since we aligned on a PMD boundary anyways, but this makes it consistent with the intention and the other fixmaps. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
