2010-05-13sh: move sh clock-cpg.c contents to drivers/sh/clk-cpg.cMagnus Damm
Move the CPG helpers to drivers/sh/clk-cpg.c V2. This to allow SH-Mobile ARM to share the code with SH. All functions except the legacy CPG stuff is moved. Signed-off-by: Magnus Damm <damm@opensource.se> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2010-05-13sh: move sh clock.c contents to drivers/sh/clk.Magnus Damm
This patch is V2 of the SH clock framework move from arch/sh/kernel/cpu/clock.c to drivers/sh/clk.c. All code except the following functions are moved: clk_init(), clk_get() and clk_put(). The init function is still kept in clock.c since it depends on the SH-specific machvec implementation. The symbols clk_get() and clk_put() already exist in the common ARM clkdev code, those symbols are left in the SH tree to avoid duplicating them for SH-Mobile ARM.

2010-05-13sh: move sh asm/clock.h contents to linux/sh_clk.h V2Magnus Damm
This patch is V2 of the clock framework move from arch/sh/include/asm/clock.h to include/linux/sh_clk.h and updates the include paths for files that will be shared between SH and SH-Mobile ARM. The file asm/clock.h is still kept in this version, this to depend on as few files as possible at this point. We keep SH specific stuff in there.

2010-05-11sh: All SH-X3 cores support NUMA and SMP, update Kconfig.Paul Mundt
Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2010-05-11sh: Ensure active regions have a backing PMB entry.Paul Mundt
In the NUMA or memory hot-add case where system memory has been partitioned up, we immediately run in to a situation where the existing PMB entry doesn't cover the new range (primarily as a result of the entry size being shrunk to match the node size early in the initialization). In order to fix this up it's necessary to preload a PMB mapping for the new range prior to activation in order to circumvent reset by MMU. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2010-05-11sh: Reject small mappings for PMB bolting.Paul Mundt
The minimum section size for the PMB is 16M, so just always error out early if the specified size is too small. This permits us to unconditionally call in to pmb_bolt_mapping() with variable sizes without wasting a TLB and cache flush for the range. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2010-05-11sh: bootmem refactoring.Paul Mundt
This reworks much of the bootmem setup and initialization code allowing us to get rid of duplicate work between the NUMA and non-NUMA cases. The end result is that we end up with a much more flexible interface for supporting more complex topologies (fake NUMA, highmem, etc, etc.) which is entirely LMB backed. This is an incremental step for more NUMA work as well as gradually enabling migration off of bootmem entirely. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
