* sh: turn off irqs when disabling CMT/TMU timersMagnus Damm2009-06-17
| | | | | | | | | | | | | Modify the CMT and TMU drivers to disable interrupts when disabling the timer. Only using start/stop bits is not enough. This fixes a bootup hang on Migo-R when the CMT is replaced by TMU for clockevents but the CMT keeps on delivering irqs even though the timer start bit is off.

* sh: Make the atomic functions safe for irqsoff tracingMatt Fleming2009-06-14
| | | | | | | | | | | | | | | The irqsoff tracer uses the atomic_* functions internally, but the implementations of those functions in arch/sh/include/asm/atomic-irq.h disable irqs to achieve atomicity. A continuous loop ensues where we disable interrupts, trace the interrupt disabling, call atomic_* functions, disable interrupts, trace the interrupt disabling, etc.. The simplest solution to all this is to just convert uses of local_irq_save()/local_irq_restore() the raw_* equivalents because the raw_* equivalents don't call trace_hardirqs_on()/trace_hardirqs_off().

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The unaligned address exception handler (and others) does not scan the fixup tables before oopsing. This is bad because it means passing a badly aligned pointer from user space might crash the kernel. Fix this by scanning the fixup tables in _exception(). This should resolve the issue for unaligned addresses as well as other less common exceptions that might be happening during a userspace access. The page fault handler already does fixup processing.

The solution is the pass a list of I2C devices in the platform data to the Open Cores driver. This is useful for MFD drivers.

Recently during migration to 2008R1.5-RC3 we losted access to the RTC. The RTC driver calls 'i2c_transfer()' which in turns calls 'bfin_twi_master_xfer()' in i2c-bfin-twi.c. Compared with 2007R1, it looks like the 2008R1.5 version of i2c-bin-twi.c has a new mode 'TWI_I2C-MODE_REPEAT' which corresponds to the Repeat Start Condition described in the HRM. However, according to the HRM, at XMIT or RECV interrupt and when the data count is 0, not only is the RESTART bit supposed to be set, but MDIR must also be set if the next operation is a receive sequence, and cleared if not. Currently there is no code that looks at the I2C_M_RD bit in the flag from the next cur_msg and set/clear the MDIR flag accordingly at the same time that the RSTART bit is set. Instead, MDIR is set or cleared (by OR'ing with 0?) after the RESTART bit has been cleared during handling of MCOMP interrupt. It appears that this is causing our failure with reading the RTC, as a quick patch to set/clear MDIR when RESTART is set seem to solve our problem.
