* 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: Expose physical addressing mode through cpuinfo.Paul Mundt2010-10-261-0/+1
| | | | | | | | | | | CPUs can be in either the legacy 29-bit or 32-bit physical addressing modes. This follows the x86 approach of tracking the phys bits in cpuinfo and exposing it to userspace through procfs. This change was requested to permit kexec-tools to detect the physical addressing mode in order to determine the appropriate address mangling. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: cache secondary CPUs idle loop.Paul Mundt2010-04-261-0/+4
| | | | | | | | This provides a cache of the secondary CPUs idle loop for the cases where hotplug simply enters a low power state instead of resetting or powering off the core. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: __cpuinit annotate the CPU init path.Paul Mundt2010-04-211-0/+1
| | | | | | | All of the regular CPU init path needs to be __cpuinit annotated for CPU hotplug. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: Tidy CPU probing and fixup section annotations.Paul Mundt2010-04-211-0/+2
| | | | | | | | This does a detect_cpu_and_cache_system() -> cpu_probe() rename, tidies up the unused return value, and stuffs it under __cpuinit in preparation for CPU hotplug. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: wire up SET/GET_UNALIGN_CTL.Paul Mundt2010-02-231-0/+12
| | | | | | | | | | This hooks up the SET/GET_UNALIGN_CTL knobs cribbing the bulk of it from the PPC and ia64 implementations. The thread flags happen to be the logical inverse of what the global fault mode is set to, so this works out pretty cleanly. By default the global fault mode is used, with tasks now being able to override their own settings via prctl(). Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh64: Fix up the build for the thread_xstate changes.Paul Mundt2010-01-191-0/+6
| | | | | | | This updates the sh64 processor info with the sh32 changes in order to tie in to the generic task_xstate management code. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: Handle early ioremaps through fixed mappings.Paul Mundt2010-01-181-0/+3
| | | | | | | This adds in a mem_init_done to work out when a standard ioremap() is possible, falling back to the fixmap based ioremap otherwise. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

* | sh: Track the CPU family in sh_cpuinfo.Paul Mundt2009-08-151-1/+12
|/ | | | | | | | | | This adds a family member to struct sh_cpuinfo, which allows us to fall back more on the probe routines to work out what sort of subtype we are running on. This will be used by the CPU cache initialization code in order to first do family-level initialization, followed by subtype-level optimizations. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: rework mode pin codeMagnus Damm2009-06-111-0/+17
| | | | | | | | | | | | | This patch reworks the mode pin code to keep the pin definitions in one place. The mode pins values are now the value of the bit instead of bit number. With this patch in place the sh7785 header file contains mode pin comments. The sh7785 clock code and the sh7785lcr board code are updated to reflect the new shared mode pins.

* sh: boot word / mode pin support V2Magnus Damm2009-06-011-0/+4
| | | | | | | | | | | | | | | | Add mode pin support for the SuperH architecture V2. With this patch applied the board code can add their own function to export the cpu mode pin configuration. In most cases this will be a constant bitmap, but boards that allow reading this from a register can instead read out the pin state from hardware. The code warns if a pin is tested but no board specific mode pin function has been provided. Signed-off-by: Magnus Damm <damm@igel.co.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
