Rework how multi-function PCI devices are identified and traversed. This fixes a bug with multi-function recovery on Power4 that was introduced by a recent Power4 EEH patch. Signed-off-by:

Modify routine that returns PCI slot status to wait for slot status to become available. This is needed, as slots that are in some remote card cage may go offline for extended periods of time. New users for this routine in following patches. Signed-off-by:

Some firmware versions will return a slot reset state of "1" when a slot is EEH frozen. Recognize this as a state that can be handled. Signed-off-by:

If a device driver does not have native PCI error recovery, a hotplug error recovery will be attemped. In this case, the device driver will not report back whether its healthy or not; simply assume that it is. Signed-off-by:

Some drivers will attempt to perform a lot of mmio even after an EEH event was detected. This is especially the case for fast cpu's and PCI-E slots. Be a bit more lenient in allowing this. Signed-off-by:

Move the slb_shadow_ptr field into the first cache line since it is (like everything there) read-only after boot. It is in fact statically initialised and thereafter only read. Signed-off-by:

To allow more robust association of each network device node with an index (such as is used by the firmware or an EEPROM to indicate MAC addresses), a network device's node may specify the index explicitly. Signed-off-by:

The --no-gzip option can be passed to the wrapper so that the kernel image is included uncompressed into the zImage. This is intended for bootloaders where the zImage itself can be compressed, or where boot time is considered more important than kernel image size. Signed-off-by:

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:

Joachim Fenkes authored
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.

ft_find_node_by_prop_value() finds nodes with the specified property/value pair. Signed-off-by:
-
Scott Wood authored
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). Signed-off-by:

Scott Wood authored
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. Signed-off-by:

When adding a property, the property name should be added to the string table if it doesn't already exist. map_string() does that; lookup_string() will fail instead. Signed-off-by:

The ft_reorder() function may change the start of the region of interest, so the pointer provided by the caller into that region must be fixed up to still point to the same datum. Signed-off-by:

Currently, if ft_get_phandle() is passed NULL it will allocate an entry for it and return a non-NULL phandle. This patch makes it simply pass the NULL through. Signed-off-by:

This name better reflects what the function does, which is to look up the phandle for an internal node pointer, and add it to the internal pointer to phandle table if not found. Signed-off-by:
