Hello,

Here's again a new set of patches to modernize Alchemy setup and PM code.
All patches have been compile-tested with db1100 and db1200 defconfigs,
and have been runnning on a few custom Au1250 boards for now more than
5 weeks.  I've suspended and resumed a few hundred times while stressing
the system (continuous SD + CF reads while playing some wave files and
compiling sources).

#1  removes unused functions
#2  removes the cpu_table and replaces it with simpler code (IMHO of course)
#3  enables use of cp0 counter as a fallback,
#4  clockevent/clocksource support using one of the 2 counters of the Au1xxx
    this also enables the use of the 'wait' instruction; depends on #3
#5  cleanup made possible with #4 
#6  don't unconditionally include the platform.c file.  Not all boards may
    want all the devices registered in there, and its existence makes adding
    platform data to certain drivers needlessly ugly.
#7  and #8 fix suspend/resume.
#9  adds DBDMA suspend/resume support.
#10 replaces sysctl suspend interface with something better (IMO).
    It's not perfect but a step in the right direction.  If the need for
    changes arises (it works fine for the demoboards) it can be done
    on top of this patch.

All patches depend on each other, have been run-tested on db1200 and
custom au1200 boards as well as compile-tested with a minimal config
for db1100.

Changes V4->V5:
- rediffed against 2.6.27-rc2+
- again minor refinements.

Changes V3->V4:
- rediffed against 2.6.27-rc1
- add patch #10.

Changes V2->V3:
- swap patches 1 and 2 
- minor refinements, no function changes.

Changes V1->V2:
- address Sergei's comments wrt. config[OD] handling
- change TOY clocksource to RTC clocksource
- add another patch (#5)


Manuel Lauss (10):
  Alchemy: remove get/set_au1x00_lcd_clock().
  Alchemy: remove cpu_table.
  MIPS: make cp0 counter clocksource/event usable as fallback.
  Alchemy: RTC counter clocksource / clockevent support.
  Alchemy: move calc_clock function.
  Alchemy: compile platform.c only when building for a demoboard.
  Alchemy: split core PM code from sysctl parts.
  Alchemy: Fix PM code for Au1200/Au1550.
  Alchemy: dbdma suspend/resume support.
  Alchemy: new demoboard userspace suspend interface.
