| | * | | | sh: Make sure all SH-X3 cores are populated in the present CPU map.Paul Mundt2010-04-26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This iterates over the maximum number of CPUs we plan to support and makes sure they're all set in the present CPU map. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
| | * | | | sh: convert online CPU map twiddling to cpumask.Paul Mundt2010-04-26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This converts from cpu_set() for the online map to set_cpu_online(). The two online map modifiers were the last remaining manual map manipulation bits, with this in place everything now goes through cpumask. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With the platform ops migration, the definitions still need to be included in the CONFIG_SMP=n case, so make the asm/smp.h include explicit. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This cribs the MIPS plat_smp_ops approach for wrapping up the platform ops.

However, 256MB isn't a valid PMB map size and pmb_merge() will actually drop the second 128MB mapping. This patch allows my SDK7786 board to boot when configured with CONFIG_MEMORY_SIZE=0x10000000.

CPUs need to specify their distribution register along with the mask definitions, as these follow the same format. Peripheral IRQs that don't opt out of balancing will be automatically distributed at the whim of the hardware block, while each CPU needs to verify whether it is handling the IRQ or not, especially before clearing the mask.

Due to the SR.IMASK interactivity, only some platforms implement this in hardware (including but not limited to SH-4A interrupt controllers, and ARM-based SH-Mobile CPUs). Each CPU needs to wire this up on its own, for now only SH7786 is wired up as an example. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

The interface clock in most cases just wraps back to the peripheral clock, while the function clock wraps in to the MSTP bits. As the logic was somewhat inverted, this cleans that up, and also enables all CPUs with SCI MSTP bits to match function clocks through clkdev lookup. As a result, this gets rid of the clk string abuse on the sh side, and the clock string will be killed off once the ARM code has had a chance to sync up. This also enables MSTP gating on CPUs like 7786 which had never wired it up before. Impacted CPUs are primarily all SH-Mobiles, SH7785, and SH7786. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

However this is not true for every archs. For example Arm needs to get this information dynamically to handle the compatiblity between different versions. To solve this, this patch proposes to drop the static HBP_NUM macro and let the arch provide the number of available slots through a new hw_breakpoint_slots() function. For archs that have CONFIG_HAVE_MIXED_BREAKPOINTS_REGS selected, it will be called once as the number of registers fits for instruction and data breakpoints together. For the others it will be called first to get the number of instruction breakpoint registers and another time to get the data breakpoint registers, the targeted type is given as a parameter of hw_breakpoint_slots().
