This patch fixes the following build error caused by commit a1dc4b59fa4af97ae68ee214d4d72bbd7c7ec1dc (sh: intc_sh5 depends on cayman board for IRQ priority table.): <-- snip --> ...

2008-05-26sh: Drop broken URAM support on SH7723.Paul Mundt1-6/+0
This was copied over from the previous MobileR bits, which doesn't apply to R2. The URAM block on R2 is recycled for the L2 instead. Signed-off-by: Paul Mundt <[email protected]>
2008-05-23sh: add probe support for new sh7723 cutMagnus Damm1-0/+1
This patch adds support for sh7723 silicon with a prr value of 0x51. Signed-off-by: Magnus Damm <[email protected]> Signed-off-by: Paul Mundt <[email protected]>
2008-05-23sh: fix VPU interrupt vector for sh7723Magnus Damm1-1/+1
This patch fixes a VPU vector typo for sh7723. The correct value is 0x980, the same as for sh7722. Signed-off-by: Magnus Damm <[email protected]> Signed-off-by: Paul Mundt <[email protected]>
2008-05-23sh: fix USBF resource for sh7722Magnus Damm1-1/+1
The USBF function on sh7722 is currently not working with the m66592_udc driver. The driver is using platform_get_resource_byname() so my commit a0d29798e568116aa6c32aef7bab2d9e620c88ad broke sh7722 support. The long term fix is to replace platform_get_resource_byname() in the driver with platform_get_resource(), but this helps until that happens.

2008-05-08sh: intc register modify fixMagnus Damm1-0/+9
Make sure register modifications stay atomic. Fixes processors with shared priority register masking. Dual bitmap masking is unaffected. Signed-off-by: Magnus Damm <[email protected]> Signed-off-by: Paul Mundt <[email protected]>
2008-05-08sh: no high level trigger on some sh3 cpusMagnus Damm1-0/+5
The processor models sh7706, sh7707 and sh7709 don't support high level trigger sense configuration. And the intc code looks like crap these days so what's the difference. Signed-off-by: Magnus Damm <[email protected]> Signed-off-by: Paul Mundt <[email protected]>
2008-05-08sh: clean up sh7710 and sh7720 intc tablesMagnus Damm2-8/+1
Clean up the intc tables by removing unneeded #ifdefs. The vector list is what selects which interrupt sources that should be added, having unsupported bitfields listed is ok as long as the vector is excluded from the list.

2008-05-08sh: add interrupt ack code to sh3Magnus Damm2-7/+87
This patch adds interrupt acknowledge code for external interrupt sources on sh3 processors. Only really required for edge triggered interrupts, but we ack regardless of sense configuration. Signed-off-by: Magnus Damm <[email protected]> Signed-off-by: Paul Mundt <[email protected]>
2008-05-08sh: unify external irq pin code for sh3Magnus Damm6-94/+75
This patch unifies the sh3 external irq pin code. It buys us some savings with reduced code redundancy, but the main feature with this change is irq sense selection support for all sh3 processors. Signed-off-by: Magnus Damm <[email protected]> Signed-off-by: Paul Mundt <[email protected]>

2008-04-18sh: Fix up L2 cache probe.Paul Mundt1-0/+6
SH7723 is the first hard silicon to implement the L2, and unsurprisingly, does the precise inverse of what the specification alleges. XOR the URAM/L2 size bits to get back in line with the existing parsing logic. Signed-off-by: Paul Mundt <[email protected]>
2008-04-18sh: Fix up SH-4A part probe.Paul Mundt1-1/+1
The SH-4A series probe we were relying on doesn't work any more on the newer parts, bump this up to use CVR.CHIP instead so we have consistent behaviour across all of the parts, which is what this should have been testing in the first place. Signed-off-by: Paul Mundt <[email protected]>

2008-03-26sh: Fix occasional FPU register corruption under preempt.Paul Mundt3-0/+3
Presently with preempt enabled there's the possibility to be preempted after the TIF_USEDFPU test and the register save, leading to bogus state post-__switch_to(). Use an explicit preempt_disable()/enable() pair around unlazy_fpu()/clear_fpu() to avoid this. Follows the x86 change.

2008-03-13sh: Fix up the address error exception handler for SH-2.Kieran Bingham1-1/+0
Presently the SH-2/SH-2A address error exception dispatch copies off the register state from the stack and skips over the first register, skewing the rest. Fix up the math here so that the proper register state is handed down to the exception handler itself. Signed-off-by: Kieran Bingham <[email protected]> Signed-off-by: Paul Mundt <[email protected]>

2008-02-26serial: Move asm-sh/sci.h to linux/serial_sci.h.Paul Mundt18-18/+18
This header is needed on other architectures as well (namely h8300), which currently fails to build without this in place. Rather than duplicating the port definition completely there, just move this to a common location instead. This should get h8300 working again for 2.6.25, in addition to the changes already pushed by Sato-san in -rc2. Signed-off-by: Paul Mundt <[email protected]>

2008-01-28sh: intc - remove default interrupt priority tablesMagnus Damm14-139/+36
This patch removes interrupt priority tables from the intc code. Optimal priority assignment varies with embedded application anyway, so keeping the interrupt priority tables together with cpu-specific code doesn't make sense. The function intc_set_priority() should be used instead to set the desired interrupt priority level. Signed-off-by: Magnus Damm <[email protected]> Signed-off-by: Paul Mundt <[email protected]>

2008-01-28sh: Preparation for uncached jumps through PMB.Stuart Menefy2-6/+6
Presently most of the 29-bit physical parts do P1/P2 segmentation with a 1:1 cached/uncached mapping, jumping between the two to control the caching behaviour. This provides the basic infrastructure to maintain this behaviour on 32-bit physical parts that don't map P1/P2 at all, using a shiny new linker section and corresponding fixmap entry.

2008-01-28sh: GUSA atomic rollback support.Stuart Menefy1-1/+23
This implements kernel-level atomic rollback built on top of gUSA, as an alternative non-IRQ based atomicity method. This is generally a faster method for platforms that are lacking the LL/SC pairs that SH-4A and later use, and is only supportable on legacy cores.
