2007-11-07sh: Kill off the remaining ST40 cruft.Paul Mundt2-9/+0
The ST40 stuff in-tree hasn't built for some time, and hasn't been updated for over 3 years. ST maintains their own out-of-tree changes and rebases occasionally, and that's ultimately where all of the ST40 users go anyways. In order for the ST40 code to be brought up to date most of the stuff removed in this changeset would have to be rewritten anyways, so there's very little benefit in keeping the remnants around either.

2007-11-07sh: Export __{s,u}divsi3_i4i on all CPUs.Paul Mundt1-2/+0
Currently these are only being exported for CONFIG_CPU_SH4. This invariably breaks when building for an SH-3 that includes multiple targets in multilib. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2007-11-07sh: Fix up kgdb-on-NMI branch target.Paul Mundt1-1/+1
This was all reworked some time ago, the old debug_enter was ripped out with everything going through a debug trap jump table instead. Kill off the debug_enter target and reference kgdb_handle_exception directly. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2007-11-07sh: Kill off duplicate includes.Paul Mundt1-1/+0
Caught by the surprisingly not-entirely-useless 'includecheck'. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2007-11-02sh: Terminate .eh_frame in VDSO with a 4-byte 0.Kaz Kojima1-1/+4
It's assumed that .eh_frame is terminated with 4-byte 0 in shared libraries and executable. It seems to be the case for VDSOs too. Without this terminator, I saw failures when unwinding from VDSO, though I don't know how other architectures handle this issue. For the normal libs, crtendS.o gives this terminator. We can use such terminating objects. Or we can add a 4-byte 0 with modifying the linker script like as the patch below.

2007-11-02sh: Decouple 4k and soft/hardirq stacks.Paul Mundt1-4/+4
While using separate IRQ stacks can cut down on stack consumption, many users can also use 4k stacks directly without the additional need of separate stacks for soft and hardirqs. With this split, we support the same rationale for 4KSTACKS as m68knommu, with the IRQSTACKS abstraction as per ppc64. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

2007-10-30sh: linker script tidying.Paul Mundt1-93/+104
Some cleanups to the SH linker script. This reorders some of the data sections for more optimal placement, general tabification, and plugging in omitted generic definitions. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

2007-10-30sh: Kill off legacy embedded ramdisk section.Paul Mundt2-22/+1
When the SH kernel used to support embedding a ramdisk in the pre-initramfs days it was placed in a special section and made to look like a regular initrd. Since that was removed ages ago, kill off the remaining cruft that was missed. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2007-10-30sh: Fix up early mem cmdline parsing.Paul Mundt1-3/+3
memory_end was being clobbered by whatever the kernel config had specified, rather than obeying the setup option. Fix this up so that memory_end is only initialized if nothing has been set on the command line. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

2007-10-19Use extended crashkernel command line on shBernhard Walle2-26/+33
This patch removes the crashkernel parsing from arch/sh/kernel/machine_kexec.c and calls the generic function, introduced in the generic patch, in setup_bootmem_allocator(). This is necessary because the amount of System RAM must be known in this function now because of the new syntax.

2007-10-19Use helpers to obtain task pid in printks (arch code)Alexey Dobriyan3-6/+7
One of the easiest things to isolate is the pid printed in kernel log. There was a patch, that made this for arch-independent code, this one makes so for arch/xxx files. It took some time to cross-compile it, but hopefully these are all the printks in arch code.

All asm/ipc.h files do only #include <asm-generic/ipc.h>. This patch therefore removes all include/asm-*/ipc.h files and moves the contents of include/asm-generic/ipc.h to include/linux/ipc.h.

2007-10-16SH vDSO: linker script indentationRoland McGrath1-35/+42
This cleans up the formatting in the vDSO linker script, mostly just the use of whitespace. It's intended to approximate the kernel standard conventions for indenting C, treating elements of the linker script about like initialized variable definitions.

2007-10-04sh: Rip out left-over nommu cond syscall cruft.Paul Mundt1-18/+0
At some point way back when (2.5 or so) quite a few syscalls hadn't yet been wired up as cond_syscalls(), so we opted to just do direct sys_ni_syscall wrapping in the assembly code instead. That's all been fixed up since then, so we can drop the wrapping. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2007-10-03sh: Make kgdb i-cache flushing less inept.Paul Mundt1-4/+4
kgdb had its own ranged I-cache flushing routine that attempted to duplicate the flush_icache_range() functionality, but managed to do an explicit D-cache writeback & invalidate twice on SH-4. This is a no-op for SH-3, and the flush_icache_range() semantics already do what kgdb was feebly attempting to do already, so just move over to that and kill off the wrapper. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2007-10-03sh: kgdb section mismatches and tidying.Paul Mundt1-42/+3
The kgdb console setup was callable from a left-over deferred initialization path, which in turn depends on __init symbols. Since the deferred initialization was removed some time ago, kill off the rest of those remnants and move kgdb_init() and friends to __init. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2007-10-02sh: early_printk tidying.Paul Mundt1-11/+4
setup_early_printk() can be static, and with that, we can kill off the early initialization variable and move the CON_BOOT check in to the function body. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2007-09-28sh: Conditionalize gUSA support.Paul Mundt3-2/+4
This conditionalizes gUSA support. gUSA is not supported on SMP configurations, and it's not necessary there anyways due to having other atomicity options (ie, movli.l/movco.l). Anything implementing the LL/SC semantics (all SH-4A CPUs) can switch to userspace atomicity implementations without requiring gUSA. This is left default-enabled on all UP so that glibc doesn't break. Those that know what they are doing can disable this explicitly. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2007-09-28sh: Tidy up gUSA preempt handling.Paul Mundt1-7/+3
Currently gUSA toggles hardirqs to disable preemption in the signal handler. Make the preemption toggling explicit, and kill off some CONFIG_PREEMPT ifdefs in the process. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2007-09-28sh: clkfwk: Support multi-level clock propagation.Stuart Menefy1-0/+2

2007-09-27sh: Fix URAM start address on SH7785.Paul Mundt1-1/+1
Not all of the SH-X2 URAM blocks are mapped in the same place, SH7785 happens to map it on the opposite end of the address space from SH7722, correct the addresses. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2007-09-27sh: Use boot_cpu_data for CPU probe.Paul Mundt4-129/+126
This moves off of smp_processor_id() and only sets the probe information for the boot CPU directly. This will be copied out for the secondaries, so there's no reason to do this each time. This also allows for some header tidying. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2007-09-27sh: Fix plat_irq_setup_pins() for SH7785.Paul Mundt1-4/+0
There was some debug code left in here that caused the pin changes to never be hit. Kill that off, and all is well. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2007-09-27sh: Disable L2 reporting for present URAM only parts.Paul Mundt1-5/+2
The probing logic works for both URAM and L2, with no way to distinguish between the two. Disable the probing for now and let the CPU subtypes that have this in a real L2 configuration explicitly say so. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

2007-09-21sh: Initial SH-X3 SMP support.Paul Mundt2-1/+125
This adds basic support for SH-X3 SMP (4 CPUs). More IPI and cache debugging is necessary, mostly interfacing the d-cache coherency and the I-cache broadcast invalidates. Only for testing at present! Signed-off-by: Magnus Damm <damm@igel.co.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>

2007-09-21sh: Bring SMP support back from the dead.Paul Mundt4-88/+118
There was a very preliminary bunch of SMP code scattered around for the SH7604 microcontrollers from way back when, and it has mostly suffered bitrot since then. With the tree already having been slowly getting prepped for SMP, this plugs in most of the remaining platform-independent bits.

2007-09-21sh: intc - initial SMP support.Magnus Damm1-21/+57

2007-09-21sh: Kill off special boot_cpu_data.Paul Mundt2-2/+7
This consolidates the cpu_data definitions and gets rid of the special boot_cpu_data. It's made a wrapper to the boot CPU, in order to keep the existing in-tree users happy. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2007-09-21sh: Make cpufreq driver less noisy on SMP.Paul Mundt1-2/+1

2007-09-21sh: intc - irl mode update for sh7780 and sh7785Magnus Damm2-4/+84
This patch contains the following fixes and improvements: - Fix address typo for INTMSK2 / INTMSKCLR2 registers on sh7780. - Adds IRQ_MODE_IRLnnnn_MASK using intc controller for IRL masking. - Good old IRQ_MODE_IRLnnnn should not register any intc controller. - plat_irq_setup_pins() now selects IRL or IRQ mode. - the holding function is now disabled using ICR0.
