2007-03-26[POWERPC] bootwrapper: Allow platforms to call library zImage_startMilton Miller
Some platforms might need to run some code before the zImage start, but could otherwise use the bss clear and relocation code. Export the start address strongly as zImage_start_lib.

2007-03-26[POWERPC] Generic time suspend/resume codeJohannes Berg
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.

When we started arch/powerpc we duplicated a number of config options from arch/ppc for various platforms that are supported. Now that we actually support a few platforms, remove all the ones that haven't been moved over. Additionally, this cleanup moved the 82xx/PQ2 options over into arch/powerpc/platforms/82xx/Kconfig where they belong. It also killed GEN550 which doesn't exist in arch/powerpc.

2007-03-16[POWERPC] ibmebus: dynamic addition/removal of adapters, some code cleanupJoachim Fenkes
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.

already top-level. Most of ft_get_parent() is factored out into __ft_get_parent(), which deals only in internal node pointers. The ft_get_parent() wrapper handles phandle conversion in both directions (previously, ft_get_parent() did not convert its return value). It also now returns NULL as the parent of the toplevel node, rather than just returning the toplevel node again (which made it rather useless in loops).

functions. The property searching part of ft_get_prop is factored out into an internal __ft_get_prop() which does not deal with phandles and does not copy the property data. ft_get_prop() is then a wrapper that does the phandle translation and copying.
