2007-09-21sh: Bring SMP support back from the dead.Paul Mundt
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.

2007-09-21sh: intc - initial SMP support.Magnus Damm
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.

2007-09-21sh: Add SMP tlbflush variants.Paul Mundt
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>
2007-09-21sh: Avoid smp_processor_id() in cache desc paths.Paul Mundt
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>
2007-09-21sh: Kill off special boot_cpu_data.Paul Mundt
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>
2007-09-21sh: Make cpufreq driver less noisy on SMP.Paul Mundt
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>

2007-09-21sh: Add maple bus support for the SEGA Dreamcast.Adrian McMenamin
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.

2007-09-21sh: Fix up extended mode TLB for SH-X2+ cores.Paul Mundt
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).

2007-09-21sh: se7206: Handle non-SuperIO I/O ports.Paul Mundt
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>

2007-09-21sh: se7206: heartbeat needs 32-bit writes.Paul Mundt
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>
2007-09-21sh: se7206: Make the I/O port routines less stupid.Paul Mundt
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>

2007-09-21sh: Don't enable FPU for SH4AL-DSP.Paul Mundt
This leads to invalid configurations where both FPU and DSP support can be enabled in the same kernel, resulting in build failure. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

2007-09-21serial: sh-sci: kgdb console build fixes.Paul Mundt
The kgdb console code requires uart_set_options() and friends, which are only provided by the serial core when console support is enabled. These were sitting under CONFIG_SH_KGDB and resulted in a link error when console support wasn't enabled, work that by rolling the console routines under CONFIG_SH_KGDB_CONSOLE, which they should have been all along.

2007-09-21sh: Fix OFFCHIP_IRQ_BASE compile error.Kristoffer Ericson
HP6xx uses OFFCHIP_IRQ_BASE to know the base irq number where non cpu interrupts should start. This define was in irq.h before, but since rework got lost. It really belongs inside hd64461.h since the hp6xx wont work without it. Signed-off-by: Kristoffer Ericson <Kristoffer.Ericson@gmail.com> Signed-off-by: Paul Mundt <lethal@linux-sh.org>

2007-09-21sh: add writesb(), readsb(), writesw() and readsw() to io.hMagnus Damm
This patch adds inline versions of writesb(), readsb(), writesw() and readsw() to include/asm-sh/io.h. Stolen from include/asm-avr32/io.h. These functions are needed to compile certain device drivers such as ax88796. Signed-off-by: Magnus Damm <damm@igel.co.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2007-09-21sh: remove sh7780 interrupt controller hack from pci codeMagnus Damm
This patch removes the sh778x specific pci code that pokes in the interrupt controller and overwrites things. The new and improved IRL code manages this in plat_irq_setup() and plat_irq_setup_pins() instead. Signed-off-by: Magnus Damm <damm@igel.co.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2007-09-21sh: intc - rework higlander irq code for r7780mp and r7785rpMagnus Damm
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.

2007-09-21sh: minor fixesMagnus Damm

2007-09-21sh: intc - irl mode update for sh7780 and sh7785Magnus Damm
This patch contains the following fixes and improvements: - Fix address typo for INTMSK2 / INTMSKCLR2 registers on sh7780. - Adds IRQ_MODE_IRLnnnn_MASK using intc controller for IRL masking. - Good old IRQ_MODE_IRLnnnn should not register any intc controller. - plat_irq_setup_pins() now selects IRL or IRQ mode. - the holding function is now disabled using ICR0. By default all external pin interrupts are disabled. Signed-off-by: Magnus Damm <damm@igel.co.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2007-09-21fb: pvr2fb: Shared IRQ for dreamcast pvr2.Adrian McMenamin
The maple bus driver (http://lkml.org/lkml/2007/9/4/165) uses hardware synchronisation between the maple bus and the VBLANK to poll the maple bus. This patch makes the interrupt shareable. By definition the interrupt is for both devices. Signed-off by: Adrian McMenamin <adrian@mcmen.demon.co.uk> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2007-09-21sh: remove CONFIG_CPU_HAS_INTC_IRQMagnus Damm
All processor specific interrupt code is now converted to make use of the new intc code. The config option CONFIG_CPU_HAS_INTC_IRQ is because of that pointless. Signed-off-by: Magnus Damm <damm@igel.co.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2007-09-21sh: Fix up heartbeat build and resource size.Paul Mundt
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>
2007-09-21sh: defconfigs for R2D-PLUS and for R2D-1Magnus Damm
This patch removes the old r2d config file named rts7751r2d_defconfig and adds separate config files for the two r2d board versions. 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.

2007-09-21sh: Overhaul spinlocks and rwlocks for SH-4A SMP.Paul Mundt
This rips out some of the old spinlock and rwlock behaviour that the SH-2 parts were using and reworks them for LL/SC semantics on the SH-4A. This is primarily only useful for SH-X3 multi-cores, but can also be used for building CONFIG_SMP=y testing kernels on SH-4A UP. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
