2010-02-23sh: wire up SET/GET_UNALIGN_CTL.Paul Mundt1-0/+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>
2010-01-19sh64: Fix up the build for the thread_xstate changes.Paul Mundt1-0/+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>
2010-01-18sh: Handle early ioremaps through fixed mappings.Paul Mundt1-0/+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>

2009-08-15sh: Track the CPU family in sh_cpuinfo.Paul Mundt1-1/+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>
2009-06-11sh: rework mode pin codeMagnus Damm1-0/+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.

2009-06-01sh: boot word / mode pin support V2Magnus Damm1-0/+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>
2009-04-16sh: Add support for SH7724 (SH-Mobile R2R) CPU subtype.Kuninori Morimoto1-1/+1
This implements initial support for the SH-Mobile R2R CPU. Based on Rev 0.11 of the initial SH7724 hardware manual. Signed-off-by: Kuninori Morimoto <morimoto.kuninori@renesas.com> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2009-03-03sh: Add support for SH7786 CPU subtype.Kuninori Morimoto1-1/+1
This adds preliminary support for the SH7786 CPU subtype. While this is a dual-core CPU, only UP is supported for now. L2 cache support is likewise not yet implemented. More information on this particular CPU subtype is available at: http://www.renesas.com/fmwk.jsp?cnt=sh7786_root.jsp&fp=/products/mpumcu/superh_family/sh7780_series/sh7786_group/ Signed-off-by: Kuninori Morimoto <morimoto.kuninori@renesas.com> Signed-off-by: Paul Mundt <lethal@linux-sh.org>

2008-07-29sh: migrate to arch/sh/include/Paul Mundt1-0/+66
This follows the sparc changes a439fe51a1f8eb087c22dd24d69cebae4a3addac. Most of the moving about was done with Sam's directions at: http://marc.info/?l=linux-sh&m=121724823706062&w=2 with subsequent hacking and fixups entirely my fault.
