* ptrace: unify FDPIC implementationsMike Frysinger2010-05-271-23/+0
| | | | | | | | | | | | | | | | The Blackfin/FRV/SuperH guys all have the same exact FDPIC ptrace code in their arch handlers (since they were probably copied & pasted). Since these ptrace interfaces are an arch independent aspect of the FDPIC code, unify them in the common ptrace code so new FDPIC ports don't need to copy and paste this fundamental stuff yet again.

* kgdb,sh: update superh kgdb exception handlingJason Wessel2010-05-201-1/+13
| | | | | | | | | | | | | | | Implement kgdb_arch_pc() which adjusts the pc if it needs to be adjusted after a software breakpoint trap. Implement kgdb_arch_set_pc() which is a new required function in the kgdb debug core. When processing a single step return zero in the error exception field so that the debug core can distinguish between a single step trap and a breakpoint trap generically.

| * sh64: provide a stub per_cpu_trap_init() definition.Paul Mundt2010-05-181-0/+5
| | | | | | | | | | | | | | | | This is needed to fix up the build at the moment. Gradually this will be reworked to follow the 32-bit initialization path and deal with delayed VBR initialization. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

| | * sh: Ensure active regions have a backing PMB entry.Paul Mundt2010-05-111-2/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>
| | * sh: bootmem refactoring.Paul Mundt2010-05-111-139/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>
| | * sh: rework memory limits to work with LMB.Paul Mundt2010-05-102-44/+39
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This reworks the memory limit handling to tie in through the available LMB infrastructure. This requires a bit of reordering as we need to have all of the LMB reservations taken care of prior to establishing the limits. While we're at it, the crash kernel reservation semantics are reworked so that we allocate from the bottom up and reduce the risk of having to disable the memory limit due to a clash with the crash kernel reservation.

| | * sh: enable LMB region setup via machvec.Paul Mundt2010-05-102-13/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | This plugs in a memory init callback in the machvec to permit boards to wire up various bits of memory directly in to LMB. A generic machvec implementation is provided that simply wraps around the normal Kconfig-derived memory start/size. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
| | * sh: bump up extra LMB reservations in bootmem init.Paul Mundt2010-05-071-4/+6
| | | | | | | | | | | | | | | | | | | | | | | | This bumps up the extra LMB reservations in ordering so that they're accounted for prior to iterating over the region list. This ensures that reservations are visible both within the LMB and bootmem context. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
| | * sh: convert initrd reservation to LMB.Paul Mundt2010-05-071-1/+1
| | | | | | | | | | | | | | | | | | This switches over from bootmem -> LMB for the initrd area reservation. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

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.
