2008-05-16sh: fix sh7785 master clock valueYoshihiro Shimoda
Signed-off-by: Yoshihiro Shimoda <shimoda.yoshihiro@renesas.com> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2008-05-09SH: catch negative denormal_subf1() retval in denormal_add()Roel Kluin
'ix' is unsigned but denormal_subf1() may return a negative int. Signed-off-by: Roel Kluin <12o3l@tiscali.nl> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2008-05-08sh: intc register modify fixMagnus Damm
Make sure register modifications stay atomic. Fixes processors with shared priority register masking. Dual bitmap masking is unaffected. Signed-off-by: Magnus Damm <damm@igel.co.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2008-05-08sh: no high level trigger on some sh3 cpusMagnus Damm
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 <damm@igel.co.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2008-05-08sh: clean up sh7710 and sh7720 intc tablesMagnus Damm
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. Signed-off-by: Magnus Damm <damm@igel.co.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2008-05-08sh: add interrupt ack code to sh3Magnus Damm
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 <damm@igel.co.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2008-05-08sh: unify external irq pin code for sh3Magnus Damm
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 <damm@igel.co.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2008-05-08sh: fix sh7705 interrupt vector typoMagnus Damm
Fix sh7705 interrupt sources for vectors 0xc80 and 0xca0. Signed-off-by: Magnus Damm <damm@igel.co.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>

2008-05-08sh64: Fixup the nommu build.Paul Mundt
Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2008-04-18sh: Fix up L2 cache probe.Paul Mundt
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 <lethal@linux-sh.org>
2008-04-18sh: Fix up SH-4A part probe.Paul Mundt
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 <lethal@linux-sh.org>
2008-04-18sh: Add support for SH7723 CPU subtype.Paul Mundt
This adds basic support for the SH7723 MobileR2 CPU. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2008-04-18sh: Fix up SH7763 build.Paul Mundt
Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2008-04-18sh: Add I2C platform data to sh7722Magnus Damm
Add platform data for the SuperH Mobile I2C block to sh7722. Signed-off-by: Magnus Damm <damm@igel.co.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2008-04-18sh: Use physical addresses for sh7722 USBF resourcesMagnus Damm
Use physical addresses and change resource name to follow data sheet. Signed-off-by: Magnus Damm <damm@igel.co.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>

2008-04-18sh: Initial support for the MX-G CPU.Paul Mundt
Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2008-03-26sh: Fix occasional FPU register corruption under preempt.Paul Mundt
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. Reported-by: Takuo Koguchi <takuo.koguchi.sw@hitachi.com> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2008-03-13sh: Fix up the address error exception handler for SH-2.Kieran Bingham
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 <kbingham@mpc-data.co.uk> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2008-03-06sh: Fix up section mismatches.Paul Mundt

2008-03-06sh: replace remaining __FUNCTION__ occurrencesHarvey Harrison
__FUNCTION__ is gcc-specific, use __func__ Signed-off-by: Harvey Harrison <harvey.harrison@gmail.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2008-02-26serial: Move asm-sh/sci.h to linux/serial_sci.h.Paul Mundt
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 <lethal@linux-sh.org>
2008-02-26sh: fix rtc_resources setup for sh770xRafael Ignacio Zurita
Fix the RTC resources setup for sh770x. Whit these proper start values RTC driver (drivers/rtc/rtc-sh.c) works. Signed-off-by: Rafael Ignacio Zurita <rizurita@yahoo.com> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2008-02-26sh: Storage class should be before const qualifierTobias Klauser
The C99 specification states in section 6.11.5: The placement of a storage-class specifier other than at the beginning of the declaration specifiers in a declaration is an obsolescent feature. Signed-off-by: Tobias Klauser <tklauser@distanz.ch> Signed-off-by: Paul Mundt <lethal@linux-sh.org>

2008-02-14sh: add support for sh7366 processorMagnus Damm
This patch adds sh7366 cpu supports. Just the most basic things like interrupt controller, clocks and serial port are included at this point. Signed-off-by: Magnus Damm <damm@igel.co.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2008-02-14sh: remove maskreg irq codeMagnus Damm
This patch removes the maskreg irq code since it is not in use anymore. Signed-off-by: Magnus Damm <damm@igel.co.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>

2008-02-08Fix container_of() usageAlexey Dobriyan
Using "attr" twice is not OK, because it effectively prohibits such container_of() on variables not named "attr".

2008-01-28sh: intc - remove default interrupt priority tablesMagnus Damm
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 <damm@igel.co.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2008-01-28sh: sh7712 clock supportAndrew Murray

2008-01-28sh: Encode L1/L2 cache shape in auxvt.Paul Mundt
This adds in the L1I/L1D/L2 cache shape support to their respective entries in the ELF auxvt, based on the Alpha implementation. We use this on the userspace libc side for calculating a tightly packed SHMLBA amongst other things. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

2008-01-28sh: Preparation for uncached jumps through PMB.Stuart Menefy
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. Signed-off-by: Stuart Menefy <stuart.menefy@st.com> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2008-01-28sh: GUSA atomic rollback support.Stuart Menefy
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.

2008-01-28sh: Add SH7263 CPU support.Paul Mundt
This adds support for the SH7263 (SH-2A) CPU. This particular CPU is a superset of SH7203, adding some additional peripheral blocks and hooking up additional (reserved on SH7203) vectors in the INTC block. No visibly nasty surprises, yet.. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
