2008-12-26cpumask: sh: Introduce cpumask_of_{node,pcibus} to replace ↵Rusty Russell1-0/+1
{node,pcibus}_to_cpumask Impact: New APIs The old node_to_cpumask/node_to_pcibus returned a cpumask_t: these return a pointer to a struct cpumask. Part of removing cpumasks from the stack. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au> Cc: Paul Mundt <lethal@linux-sh.org>
2008-12-25[S390] arch_setup_additional_pages argumentsMartin Schwidefsky2-3/+2
arch_setup_additional_pages currently gets two arguments, the binary format descripton and an indication if the process uses an executable stack or not. The second argument is not used by anybody, it could be removed without replacement. What actually does make sense is to pass an indication if the process uses the elf interpreter or not. The glibc code will not use anything from the vdso if the process does not use the dynamic linker, so for statically linked binaries the architecture backend can choose not to map the vdso.

2008-12-22sh: add UIO support for JPU on SH7722.Takanari Hayama1-0/+31
Add JPU support on Migo-R via UIO. This make use of Magnus's generic UIO platform driver. Chunk of contiguous memory to hold intermediate image and compressed data during encode and decode. Signed-off-by: Takanari Hayama <taki@igel.co.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>

2008-12-22sh: enable deferred io LCDC on Migo-RMagnus Damm1-0/+2
Enable LCDC deferred io on Migo-R using 1s delay. As with other deferred io frame buffers user space code should use fsync() on the frame buffer device to trigger an update. Signed-off-by: Magnus Damm <damm@igel.co.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2008-12-22sh: add LCDC interrupt configuration to AP325 and Migo-RMagnus Damm2-0/+8
Add LCDC interrupt resources for AP325 and Migo-R. The LCDC driver does not require interrupts at this point, but changes such as one-shot SYS mode using deferred io, and wait-for-vblank will both need this.

2008-12-22sh: dma: Kill off ISA DMA wrapper.Paul Mundt3-110/+0
There are no more users for this code, and it has been deprecated for some time, so just kill it off. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2008-12-22sh: Conditionalize the code dumper on CONFIG_DUMP_CODE.Paul Mundt3-1/+22
We don't really want this enabled by default, but it is still quite useful for debugging. So, make it conditional and leave it off by default. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2008-12-22sh: Kill off the unused SH_ALPHANUMERIC debug option.Paul Mundt1-8/+2
Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2008-12-22sh: Enable skipping of bss on debug platforms for sh32 also.Paul Mundt2-5/+22
This enables the same functionality that sh64 has for sh32. When running on simulated hardware or via remote memory via the debug interface, memory is gauranteed to be zero on boot already, and skipping the zeroing of BSS has measurable boot time benefits. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2008-12-22doc: Update sh cpufreq documentation.Paul Mundt1-2/+6
The sh cpufreq driver is no longer limited to just the SH-3 and SH-4, update the documentation to reflect this fact accordingly. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2008-12-22sh: mrshpc_setup_windows() needs to be inline.Paul Mundt1-1/+1
While no one should be including this file multiple times, flag it inline anyways just in case. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2008-12-22sh: Kill off cf-enabler with extreme prejudice.Paul Mundt8-220/+63
Now that the rest of the boards that were using cf-enabler "generically" have switched to setting up their mappings on their own, only the mach-se boards were left using it. All of the cf-enabler using mach-se boards use a special initialization of the MRSHPC windows rather than going through the special PTE as other SH-4 platforms do. This consolidates the MRSHPC setup logic, hooks it up on the boards that care, and gets rid of any and all remaining references to cf-enabler. This has been long overdue, as cf-enabler has been the bane of arch/sh/kernel for the last 7 years. Good riddance. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

2008-12-22sh: mach-microdev: Split out the fdc37c93xapm initialization code.Paul Mundt3-181/+167
This makes the microdev code a bit more readable, and moves the setup for the SuperIO out on its own. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2008-12-22sh: mach-sh03: Use __set_io_port_base(), kill off special ioport_map().Paul Mundt2-10/+2
This also fixes up a long-standing bug for this platform where the PIO base was set to a register offset, rather than the actual PIO offset itself. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2008-12-22sh: mach-sh03: Move off of cf_enabler to pata_platform, as per landisk.Paul Mundt2-6/+35
This gets rid of the cf enabler use on mach-sh03 and switches to use pata_platform with the proper address directly. cf_enabler is subsequently disabled for mach-sh03. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2008-12-22sh: board-shmin: Convert shmin to use __set_io_port_base().Paul Mundt1-11/+3
Drop the special mv_ioport_map() implementation, as this can simply use __set_io_port_base() directly. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2008-12-22sh: Simplify kernel_thread_helper() for sh32.Paul Mundt1-15/+4
This can use the same implementation as sh64, the generated assembly is the same between the new and old version, so there is not much point in leaving it open coded in inline assembly. This is preparatory work for future consolidation of the _32/_64 variants. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2008-12-22sh: Kill off mv_heartbeat() from the machvec.Paul Mundt3-12/+0
Nothing is using this any more, so get rid of it before anyone gets the bright idea to start using it again. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2008-12-22sh: Kill off the cayman and microdev special heartbeat code.Paul Mundt5-166/+0
These can use the generic code instead. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2008-12-22sh: Kill off sh_bios_in_gdb_mode().Paul Mundt2-18/+0
With the reworked kgdb support, we always detach and reinitialize the stub. This was mostly a feature for handoffs between sh-ipl+g and the kgdb stub, but virtually no sh-ipl+g versions ever had this working right in the first place. Given that the sh-ipl+g stubs in general use today don't even support the GDB stub, and we have already killed off the special casing in the sh-sci serial driver, kill off this now unused symbol too.

2008-12-22sh: oprofile: Refactor common setup code for multiple driver support.Paul Mundt4-30/+178
This re-implements the old op_model_null code in to something more generic, where multiple drivers, backtrace, etc. can all be interfaced. Based largely on arch/mips/oprofile/common.c. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

2008-12-22sh: Convert Cayman boards from hw_interrupt_type to irq_chipMatt Fleming1-27/+8

2008-12-22sh: Convert Dreamcast support from hw_interrupt_type to irq_chipMatt Fleming2-106/+91
Switch the dreamcast IRQ code over to the irq_chip way of doing things, so that we can set GENERIC_HARDIRQS_NO__DO_IRQ for all SuperH boards. Also, whilst I'm here change some things to make checkpatch.pl happy: - Indent with tabs, not with spaces - Include <linux/io.h>, not <asm/io.h> - Fix the multi-line comment style - Fix some typos in the comments Tested-by: Adrian McMenamin <adrian@newgolddream.dyndns.info> Signed-off-by: Matt Fleming <mjf@gentoo.org> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
