I've tested serial, MMC, smsc911x and wl12xx on zoom3. As my
omap is an early ES revision, I have not been able to test
off-idle on this one. But anyways, I'd say we have enough
device tree support for the zoom to be able to drop the
board-zoom files. Patches are welcome to add further features
to this .dts file.

I've tested the serial, MMC, smsc911x, wl12xx, and off-idle support
with the pinctrl patches, so it probably works better than the
board-*.c files ever did. Also the board-omap3evm.c file is broken
for the DSS, and has been for a while. Patches are welcome to fix
it in this .dts file, let's just drop the board-*.c file for this.

Note that off-idle currently requires doing request_irq() on the
wake-up pin from pinctrl-single IRQ domain until we can handle
that in some Linux generic way.

Looks like the main difference between the TMDSEVM3530 and
TMDSEVM3730 is just the omap processor:

http://www.ti.com/tool/tmdsevm3530
http://www.ti.com/tool/tmdsevm3730

So let's add a common file for the EVMs, and fix the description
for the omap3-evm.dst as that's clearly for the TMDSEVM3530
since it includes omap34xx.dtsi. It cannot support the TMDSEVM3730
properly, and we need a separate file for that in the following
patch.

THis is because the Exynos u-boot, for example on the Chromebooks, doesn't set

Running an "echo t > /proc/sysrq-trigger" crashes the parisc kernel.  The
problem is, that in print_worker_info() we try to read the workqueue info via
the probe_kernel_read() functions which use pagefault_disable() to avoid
crashes like this:
    probe_kernel_read(&pwq, &worker->current_pwq, sizeof(pwq));
    probe_kernel_read(&wq, &pwq->wq, sizeof(wq));
    probe_kernel_read(name, wq->name, sizeof(name) - 1);

The problem here is, that the first probe_kernel_read(&pwq) might return zero
in pwq and as such the following probe_kernel_reads() try to access contents of
the page zero which is read protected and generate a kernel segfault.

With this patch we fix the interruption handler to call parisc_terminate()
directly only if pagefault_disable() was not called (in which case
preempt_count()==0).  Otherwise we hand over to the pagefault handler which
will try to look up the faulting address in the fixup tables.

ARCompact TRAP_S insn used for breakpoints, commits before exception is
taken (updating architectural PC). So ptregs->ret contains next-PC and
not the breakpoint PC itself. This is different from other restartable
exceptions such as TLB Miss where ptregs->ret has exact faulting PC.
gdb needs to know exact-PC hence ARC ptrace GETREGSET provides for
@stop_pc which returns ptregs->ret vs. EFA depending on the
situation.

However, writing stop_pc (SETREGSET request), which updates ptregs->ret
doesn't makes sense stop_pc doesn't always correspond to that reg as
described above.

This was not an issue so far since user_regs->ret / user_regs->stop_pc
had same value and both writing to ptregs->ret was OK, needless, but NOT
broken, hence not observed.

With gdb "jump", they diverge, and user_regs->ret updating ptregs is
overwritten immediately with stop_pc, which this patch fixes.
