The "EET" variant of the pcm037 board has an OLED display, using a S6E63D6
display controller on the first SPI interface, using GPIO57 as a chip-select
for it. S6E63D6 is initialised in the boot-loader, so we only have to take care
of the LCD. EET also adds several buttons and LEDs on GPIOs. This patch adds a
"pcm037_variant=" kernel command line parameter to specify at boot-time which
board the kernel is running on, default is "pcm970", specify "eet" for the EET
board.

The recent deprecation of dma_sync_{sg,single} ironically broke Blackfin
systems.  This is because we don't define dma_sync_sg_for_cpu at all, so
until the DMA asm-generic conversion/cleanup is done after the next
release, simply stub out the dma_sync_sg_for_{cpu,device} functions.

Many aspects of the Blackfin memory map is exactly the same across all
variants.  Rather than copy and paste all of these duplicated values in

file.  In the process, push down BF561 SMP specific stuff to the BF561

Rather than use "Linux" in the boot image name (as this is redundant --
the image type is already set to "linux"), use the CPU name.  This makes
it fairly obvious when a wrong image is accidentally booted.  Otherwise
there is no kernel output and you waste time scratching your head
wondering wtf just happened.

The current cache options don't really represent the hardware features.
They end up setting different aspects of the hardware so that the end
result is to turn on/off the cache.  Unfortunately, when we hit cache
problems with the hardware, it's difficult to test different settings to
root cause the problem.  The current settings also don't cleanly allow for
different caching behaviors with different regions of memory.

So split the configure options such that they properly reflect the settings
that are applied to the hardware.

We read the SWRST (Software Reset) register to get at the last reset
state, and then we may configure the DOUBLE_FAULT bit to control behavior
when a double fault occurs.  But if the lower bits of the register is
already set (like UART boot mode on a BF54x), we inadvertently make the
system reset by writing to the SYSTEM_RESET field at the same time.  So
make sure the lower 4 bits are always cleared.

With the common IRQ code initializing much more of the irq_desc state, we
can't blindly initialize it ourselves to the local bad_irq state.  If we
do, we end up wrongly clobbering many fields.  So punt most of the bad irq
code as the common layers will handle the default state, and simply call
handle_bad_irq() directly when the IRQ we are processing is invalid.

pm_idle is used by infrastructure (eg, cpuidle) which expects architectures
to call it in a certain way.  Arrange for ARM to follow x86's lead on this
and call pm_idle() with interrupts already disabled.  However, we expect
pm_idle() to enable interrupts before it returns.

Also, OMAP wants to be able to disable hlt-ing, so allow hlt_counter to
prevent all calls to pm_idle.

get_krobe_ctlblk returns a per cpu kprobe control block which holds
the state of the current cpu wrt to kprobe.
When inserting/removing a kprobe the state of the cpu which replaces
the code is changed to KPROBE_SWAP_INST. This however is done when
preemption is still enabled. So the state of the current cpu doesn't
necessarily reflect the real state.
To fix this move the code that changes the state to non-preemptible
context.
