We need some more page flags to hook up _PAGE_WIRED (and eventually other things). So use the unused PTE bits above the PPN field as no implementations use these for anything currently. Now that we have _PAGE_WIRED let's provide the SH-5 functions for wiring up TLB entries. Signed-off-by: NMatt Fleming <matt@console-pimps.org>

Provide a new extended page flag, _PAGE_WIRED and an SH4 implementation for wiring TLB entries and use it in the fixmap code path so that we can wire the fixmap TLB entry. Signed-off-by: NMatt Fleming <matt@console-pimps.org>

Previously this was only built in for Urquell boards, but the same approach can be used on SDK7786 now that the mode pin reading is supported, so make it generic to SH7786. Signed-off-by: NPaul Mundt <lethal@linux-sh.org>

Presently the secondary CPU entry point is only aimed at 29bit phys mode, causing it to point to a stray virtual address in 32bit mode. Fix it up after consulting with our shiny new __in_29bit_mode(). Signed-off-by: NPaul Mundt <lethal@linux-sh.org>

flush_cache_all() gets called in to when we do some early ioremapping. Unfortunately on SDK7786 the interrupt controller itself requires ioremapping, leading to a bit of a chicken and egg scenario. For now, don't bother with IPI crosscalls if there aren't any other CPUs online. Signed-off-by: NPaul Mundt <lethal@linux-sh.org>

This updates the existing boards that specify the register width through platform data to use the resource flags instead. This eliminates platform data completely in most cases, and permits further improvement in the heartbeat driver as well as shrinking the overall private data size.

This stubs in some preliminary board support for the RTE SDK7786. This is quite stunted at the moment, and primarily builds on top of the system FPGA. FPGA IRQs are handled via CPU IRL masking for simplicity, with initial peripheral support restricted to the debug ethernet.

All SH-X2 and SH-X3 parts support an extended TLB mode, which has been left as experimental since support was originally merged. Now that it's had some time to stabilize and get some exposure to various platforms, we can drop it as an option and default enable it across the board. This is also good future proofing for newer parts that will drop support for the legacy TLB mode completely. This will also force 3-level page tables for all newer parts, which is necessary both for the varying page sizes and larger memories. Signed-off-by: NPaul Mundt <lethal@linux-sh.org>

This stubs out all of the PxSEGADDR() wrappers for non-legacy code. 29-bit will continue to work with these, while 32-bit code will now blow up on compile rather than at runtime. The vast majority of the in-tree offenders are gone, with the only remaining culprits being unable to support 32-bit mode. Hopefully this will prevent anyone from ever using these again.

This introduces some much overdue chainsawing of the fixed PMB support. fixed PMB was introduced initially to work around the fact that dynamic PMB mode was relatively broken, though they were never intended to converge. The main areas where there are differences are whether the system is booted in 29-bit mode or 32-bit mode, and whether legacy mappings are to be preserved. Any system booting in true 32-bit mode will not care about legacy mappings, so these are roughly decoupled. Regardless of the entry point, PMB and 32BIT are directly related as far as the kernel is concerned, so we also switch back to having one select the other. With legacy mappings iterated through and applied in the initialization path it's now possible to finally merge the two implementations and permit dynamic remapping overtop of remaining entries regardless of whether boot mappings are crafted by hand or inherited from the boot loader.

This follows the x86 xstate changes and implements a task_xstate slab cache that is dynamically sized to match one of hard FP/soft FP/FPU-less. This also tidies up and consolidates some of the SH-2A/SH-4 FPU fragmentation. Now fpu state restorers are commonly defined, with the init_fpu()/fpu_init() mess reworked to follow the x86 convention. The fpu_init() register initialization has been replaced by xstate setup followed by writing out to hardware via the standard restore path. As init_fpu() now performs a slab allocation a secondary lighterweight restorer is also introduced for the context switch. In the future the DSP state will be rolled in here, too. More work remains for math emulation and the SH-5 FPU, which presently uses its own special (UP-only) interfaces. Signed-off-by: NPaul Mundt <lethal@linux-sh.org>

This adds some VBR sanity checks in the sh_bios code to ensure that the BIOS VBR is in range before blindly trapping in to it.

Now that the sh-sci earlyprintk is taken care of by the sh-sci driver directly, there's no longer any reason for having a split-out early_printk framework. sh_bios is the only other thing that uses it, so we just migrate the leftovers in to there. As it's possible to have multiple early_param()'s for the same string, there's not much point in having this split out anymore anyways, particularly since the sh_bios dependencies are still special-cased within sh-sci itself.

As SH has a very sparse IRQ map by default, all new CPUs and boards benefit from using sparseirq by default. Despite this, there are still a few stragglers (mostly due to using a fixed IRQ range for their FPGA IRQ mappings), and these still need to be converted over one by one. As these are now in the minority, and we do not want to encourage this sort of brain-damage in newer board ports, we force sparseirq on. Signed-off-by: NPaul Mundt <lethal@linux-sh.org>

Revert commit 2fbd07a5, as this commit breaks an IBM platform with quad-core Xeon cpu's. According to Suresh, this might be an IBM platform issue, as on other Intel platforms with <= 8 logical cpu's, logical flat mode works fine irespective of physical apic id values (inline with the xapic architecture). Revert this for now because of the IBM platform breakage. Another version will be re-submitted after the complete analysis.
