* sh: nommu: Kill off dummy page fault ops for SH-3/4.Paul Mundt2007-09-242-67/+0
| | | | | | | | We stopped referencing these functions unconditionally when the old entry.S code was refactored, so this is just dead code at present. Kill it off. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: Fix alias calculation for non-aliasing cases.Paul Mundt2007-09-241-2/+2
| | | | | | | | | | | There was an off-by-1 on the cache alias detection logic on SH-4, which caused n_aliases to always be 1 even when the page size precluded the existence of aliases. With this corrected, 64KB pages happily reports n_aliases == 0, and hits the appropriate fast paths in the flushing routines. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: Initial SH-X3 SMP support.Paul Mundt2007-09-214-208/+375
| | | | | | | | | | | This adds basic support for SH-X3 SMP (4 CPUs). More IPI and cache debugging is necessary, mostly interfacing the d-cache coherency and the I-cache broadcast invalidates. Only for testing at present! Signed-off-by: Magnus Damm <damm@igel.co.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: Plug plat_smp_setup() in to generic setup path.Paul Mundt2007-09-211-0/+5
| | | | | | | Now that the SMP stubs are in place, call in to the setup code to be defined by the platform. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

* sh: Bring SMP support back from the dead.Paul Mundt2007-09-214-88/+118
| | | | | | | | | | | There was a very preliminary bunch of SMP code scattered around for the SH7604 microcontrollers from way back when, and it has mostly suffered bitrot since then. With the tree already having been slowly getting prepped for SMP, this plugs in most of the remaining platform-independent bits.

* sh: intc - initial SMP support.Magnus Damm2007-09-211-21/+57
| | | | | | | | | | | | This implements initial support for the SMP INTC (particularly INTC2) controllers. These are largely implemented as conventional blocks, with register sets grouped together at fixed strides relative to the CPU id.

* sh: Add SMP tlbflush variants.Paul Mundt2007-09-211-0/+140
| | | | | | | | This adds the TLB flushing routines for SMP systems, based on the MIPS implementation, with some additional SH-specific flush routines. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: Avoid smp_processor_id() in cache desc paths.Paul Mundt2007-09-211-31/+31
| | | | | | | | | current_cpu_data uses smp_processor_id() in order to find the corresponding cpu_data. As the cache descs are all currently identical, just have this look at probed results from the boot CPU. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: Kill off special boot_cpu_data.Paul Mundt2007-09-212-2/+7
| | | | | | | | This consolidates the cpu_data definitions and gets rid of the special boot_cpu_data. It's made a wrapper to the boot CPU, in order to keep the existing in-tree users happy. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: Make cpufreq driver less noisy on SMP.Paul Mundt2007-09-211-2/+1
| | | | | | | The cpufreq driver banner is currently printed for each CPU, move it down so it's not as noisy and it's only printed once. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

* sh: Add maple bus support for the SEGA Dreamcast.Adrian McMenamin2007-09-211-0/+11
| | | | | | | | | | | | | | | | | | | | | The Maple bus is SEGA's proprietary serial bus for peripherals (keyboard, mouse, controller etc). The bus is capable of some (limited) hotplugging and operates at up to 2 M/bits. Drivers of one sort or another existed/exist for 2.4 and a rudimentary port, which didn't support the 2.6 device driver model was also in existence. This driver - for the bus logic itself and for the keyboard (other drivers will follow) are based on the code and concepts of those old drivers but have lots of completely rewritten parts. I have the maple bus code as a built in now as that seems the sane and rational way to handle something like that - you either want the bus or you don't.

* sh: Fix up extended mode TLB for SH-X2+ cores.Paul Mundt2007-09-211-17/+13
| | | | | | | | | | | | | | | | The extended mode TLB requires both 64-bit PTEs and a 64-bit pgprot, correspondingly, the PGD also has to be 64-bits, so fix that up. The kernel and user permission bits really are decoupled in early cuts of the silicon, which means that we also have to set corresponding kernel permissions on user pages or we end up with user pages that the kernel simply can't touch (!). Finally, with those things corrected, really enable MMUCR.ME and correct the PTEA value (this simply needs to be the upper 32-bits of the PTE, with the size and protection bit encoding).

| | | | | | | | | This fixes up the port calculation logic for non-SuperIO accesses, before these were always matching the MRSHPC base, now just make sure the original port is handed back if it's not in the I/O port range. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

* sh: se7206: heartbeat needs 32-bit writes.Paul Mundt2007-09-211-0/+1
| | | | | | | | Most boards use 8 or 16-bit access for the LED bank, se7206 needs 32. There's only 8 individual LEDs however, each with a 'special' value in terms of logical ordering. Go FPGA, go! Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: se7206: Make the I/O port routines less stupid.Paul Mundt2007-09-212-33/+4
| | | | | | | The port routines were logically inverted, and the MRSHPC range had no upper bound, causing 8 and 16-bit port I/O to get mangled. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

* sh: remove sh7780 interrupt controller hack from pci codeMagnus Damm2007-09-211-13/+0
| | | | | | | | | | This patch removes the sh778x specific pci code that pokes in the interrupt controller and overwrites things.

* sh: intc - rework higlander irq code for r7780mp and r7785rpMagnus Damm2007-09-215-19/+152
| | | | | | | | | | | | | This patch reworks the highlander irq code for r7780mp and r7785rp. The same strategy as for the new R2D code is used here - the board specific interrupts are now starting from HL_FPGA_IRQ_BASE. The code for r7780rp is not touched due to lack of hardware. Tested with CF, AX88796 on r7780mp and r7785rp. The touch switch interrupt has also been tested on r7780mp.

| | | | | | | | | We were abusing the resource size for the number of bits, this has been reworked using proper platform data, so this can be tidied up now. Boards in general only have a 1-byte wide resource, which the ioremap_nocache() case already handles. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

The two new defconfigs are identical with the exception of board selection: - rts7751r2dplus_defconfig selects CONFIG_RTS7751R2D_PLUS=y - rts7751r2d1_defconfig selects CONFIG_RTS7751R2D_1=y Please remember to update both files with r2d changes in the future.
