| * [S390] arch_setup_additional_pages argumentsMartin Schwidefsky2008-12-25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | 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.

* | sh: dma: Kill off ISA DMA wrapper.Paul Mundt2008-12-22
| | | | | | | | | | | | | | 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>
* | sh: Conditionalize the code dumper on CONFIG_DUMP_CODE.Paul Mundt2008-12-22
| | | | | | | | | | | | | | | | 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>

* | sh: Enable skipping of bss on debug platforms for sh32 also.Paul Mundt2008-12-22
| | | | | | | | | | | | | | | | | | 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.

* | sh: Kill off cf-enabler with extreme prejudice.Paul Mundt2008-12-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>

* | sh: mach-microdev: Split out the fdc37c93xapm initialization code.Paul Mundt2008-12-22
| | | | | | | | | | | | | | 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>
* | sh: mach-sh03: Use __set_io_port_base(), kill off special ioport_map().Paul Mundt2008-12-22
| | | | | | | | | | | | | | | | 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>
* | sh: mach-sh03: Move off of cf_enabler to pata_platform, as per landisk.Paul Mundt2008-12-22
| | | | | | | | | | | | | | | | 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>
* | sh: board-shmin: Convert shmin to use __set_io_port_base().Paul Mundt2008-12-22
| | | | | | | | | | | | | | 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>

* | sh: Simplify kernel_thread_helper() for sh32.Paul Mundt2008-12-22
| | | | | | | | | | | | | | | | | | | | | | 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>
* | sh: Kill off mv_heartbeat() from the machvec.Paul Mundt2008-12-22
| | | | | | | | | | | | | | 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>
* | sh: Kill off the cayman and microdev special heartbeat code.Paul Mundt2008-12-22

* | sh: Kill off sh_bios_in_gdb_mode().Paul Mundt2008-12-22
| | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | I've been unable to even compile-test this change because I don't have an sh5 toolchain.

* | sh: Generic kgdb stub support.Paul Mundt2008-12-22
| | | | | | | | | | | | | | | | This migrates from the old bitrotted kgdb stub implementation and moves to the generic stub. In the process support for SH-2/SH-2A is also added, which the old stub never provided. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

| | | | | | | | | | | | | | | | | | | | | | This converts the sh64 /proc/asids entry to debugfs and enables it for all SH parts that have debugfs enabled. On MMU systems this can be used to determine which processes are using which ASIDs which in turn can be used for finer grained cache tag analysis. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

| | | | | | | | | | | | | | | | These were left over from some time ago, sh64 never got around to defining __HAVE_ARCH_TASK_STRUCT_ALLOCATOR during the conversion, and it has no need to. Kill these off and use the generic versions instead. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
