* sh: Fix up breakage from asm-generic/pgtable.h changes.Paul Mundt2011-01-141-0/+1
| | | | | | | | | | | | | | We require a forward declaration for mm_struct: In file included from arch/sh/include/asm/pgtable.h:163, from arch/sh/include/asm/io.h:21, from arch/sh/kernel/machvec.c:20: include/asm-generic/pgtable.h:104: error: 'struct mm_struct' declared inside parameter list include/asm-generic/pgtable.h: In function 'ptep_get_and_clear_full': include/asm-generic/pgtable.h:107: error: passing argument 1 of 'ptep_get_and_clear' from incompatible pointer type include/asm-generic/pgtable.h:70: note: expected 'struct mm_struct *' but argument is of type 'struct mm_struct *' Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* 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/+1
| | | | | | | | | 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>

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.

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>

|/ | | | | | | | | | | | | | | | | | | | | | Since we no longer need to provide KM_type, the whole pte_*map_nested() API is now redundant, remove it.

| * sh: Provide a generic SRAM pool for tiny memories.Paul Mundt2010-10-151-0/+38
| | | | | | | | | | | | | | | | | | | | | | | | This sets up a generic SRAM pool for CPUs and platform code to insert their otherwise unused memories into. A simple alloc/free interface is provided (lifed from avr32) for generic code. This only applies to tiny SRAMs that are otherwise unmanaged, and does not take in to account the more complex SRAMs sitting behind transfer engines, or that employ an I/D split.
