* [POWERPC] 86xx/85xx: Move 8641 PCI-Express to arch/powerpc/sysdev/fsl_pcie.c.Jon Loeliger2007-03-26
| | | | | | | | | | This move sets the stage for the use of generic PCI Express code in 85xx and 86xx parts from FSL. Subsequent patches for 8548 and 8544 will be able to use this shared code.

* [POWERPC] New reg.h for the zImageDavid Gibson2007-03-26
| | | | | | | | | | | This patch adds a reg.h to the zImage code, with common definitions for accessing system registers. For now, this includes functions for retrieving the PVR and the stack pointer. This patch then uses the new reg.h to let start() display the running stack address without having to explicitly pass the stack as a parameter from the asm code.

* [POWERPC] Add gcc format warnings to zImage printf()David Gibson2007-03-26
| | | | | | | | | | This patch adds the correct attributes to the zImage's versions of printf to make gcc generate format string mismatch warnings.

* [POWERPC] boot: Use a common zImage ruleMilton Miller2007-03-26
| | | | | | | | | | | | | | | 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.

* [POWERPC] boot: clean rule fixesMilton Miller2007-03-26
| | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* [POWERPC] Update documentation for flat device tree format v17David Gibson2007-03-16
| | | | | | | | | | | | | | | | | | | | | | | This patch updates booting-without-of.txt to describe version 17 of the flattened device tree format. Version 17 is a small, backwards compatible change from version 16, adding an extra field giving the size of the device tree's structure block. At this time, the kernel has no use for the extra information, however its presence can make life easier for bootloaders or other software manipulating the tree. In addition this patch adds information on the size_dt_strings field of the device tree header, present since version 3 of the flattened tree format, but omitted from the documentation. It also makes changes to consistently refer to versions 16 and 17 as versions 16 and 17 in decimal, rather than version 0x10 which was occasionally used for version 16 previously. Finally, we also add the new field to the definition of the device tree header structure in prom.h Signed-off-by: David Gibson <david@gibson.dropbear.id.au> Acked-by: Jon Loeliger <jdl@freescale.com> Signed-off-by: Paul Mackerras <paulus@samba.org>

* [POWERPC] ibmebus: dynamic addition/removal of adapters, some code cleanupJoachim Fenkes2007-03-16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
