This patch enables/disables the option to register to be
notified about bridge driver PWR errors, generally caused
because the timer expires waiting for the dsp to change from
active to retention or hibernation.
This event, if enabled, will be signaled as a fatal error,
bridge driver will be unusable until a recovery method
cleans the error state.

If enable_off_mode is not set bridge target state going into
suspend will be retention, on this path the peripheral clocks
will be disabled but not enabled again when waking the dsp up.

Remove busy waiting on suspend and self hibernation paths by
removing udelays.
Decrease the total timer waiting on power transitions to be less
than 3 seconds, defined to wait for power transition approx. 200 msecs
Change required for:

- *! eliminate scope param, use DBL_Symbol. Pass attrs to
- *! DBL_load(), DBL_unload().
- *! 20-Nov-2001 jeh Removed DBL_loadArgs().
- *! 07-Sep-2001 jeh Added overlay support.
- *! 31-Jul-2001 jeh Include windows.h.

Avoid calls to read the register if pDevContext is available
to the function, this will save a call to query and hold
a semaphore under registry operations.

This breaks the build when DVFS is enabled, because of:
status = HW_MBOX_saveSettings(resources.dwMboxBase);

BTW. Nobody is checking for errors in the 'status' variable.

The commit message is not clear: Why do we want this? What problem is
fixed? Is old behavior changed, or is it an independent feature?

I'm guessing this means you found a bug and this patch fixes it. This
can be clarified on the commit message, right?

The patches look good to me. Except #16... if I revert it everything
works on the N900, so that's progress :)

Yes, this was removed in old patches, so patch assumes it is not there. I'll drop from the series for now.

New commit message:
"Trampolines" utilize memory space containing a local jump
table to hit external locations. Instead of the "near"
function call directly calling the external location it
"calls" a trampoline entry.
A "near" function call requires the target to be within a
signed, 21-bit offset from the current PC so all calls have
to be within 4MB of the current execution point.
The trampoline entry (location in memory) contains an
unconditional long branch to the external address to be
called. When the called function returns, the PC is returned
to the original calling location since that is where the
link register points, as the trampoline utilizes a branch
instruction.
Utilizing this method removes the 4MB location restriction
as well since the long branch can be done within all of DSP
addressable space.
This doesn't require any change on the dsp side, it is an
enhancement for newer DSP side binaries.
