9da82a6dee [POWERPC] boot: Use a common zImage rule
Before the plethora of platforms gets any worse, establish a common
rule to invoke the wrapper for any platform.  Add arguments to
the rule for initrd, dts, dtb, etc.   Show example usage with initrd.

Create default rules for zImage, and zImage.initrd.  initrd targets
depend on the ramdisk file.

Don't consider targets for zImage.initrd that are targets for zImage.
This means uImage is no longer considered a target for zImage.initrd.

5d7960ffb8 [POWERPC] boot: clean rule fixes
Now that obj-boot is in targets, we can remove (twice) it from clean-files.
zImage.initrd was missing, move zImage nearer where its used, and place
zImage.initrd next to it.  Remove non-ported zImage.sandpoint, and add
auto-generation of unconfigured zImage.initrd* like image-.

17e638bc28 [POWERPC] Generic time suspend/resume code
This removes the time suspend/restore code that was done through
a PMU notifier in arch/platforms/powermac/time.c.

Instead, introduce arch/powerpc/sysdev/timer.c which creates a sys
device and handles time of day suspend/resume through that.

This should probably be replaced by using the generic RTC framework
but for now it gets rid of the arcane powermac specific hack.

6bccf755ff [POWERPC] ibmebus: dynamic addition/removal of adapters, some code cleanup
This adds two sysfs attributes to /sys/bus/ibmebus which can be used to
notify the ebus driver of added / removed ebus devices in the OF device
tree.

Echoing the device's location code (as found in the OFDT "ibm,loc-code"
property) into the "probe" attribute will notify ebus of addition of the
device and cause the appropriate device driver's probe function to be called
on the device.

Likewise, echoing the location code into the "remove" attribute will cause
the device to be removed from the system.

The writes will block until the respective operation has finished and return
an error code if the operation failed.

In addition, two minor tidbits are fixed:

- The fake root device used to provide a common parent for all ebus devices
  is now based on device instead of of_device - it had no associated devtree
  node. This saves several checks throughout the ebus driver.

- The sysfs attributes are now generated automagically by device_register()
  instead of by the ibmebus code, which saves a few compiler warnings about
  unused return codes.
