[POWERPC] Update documentation for flat device tree format v17
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

[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.

[POWERPC] zImage: Cleanup and improve zImage entry point
This patch re-organises the way the zImage wrapper code is entered, to
allow more flexibility on platforms with unusual entry conditions.
After this patch, a platform .o file has two options:
1) It can define a _zimage_start, in which case the platform code gets
control from the very beginning of execution. In this case the
platform code is responsible for relocating the zImage if necessary,
clearing the BSS, performing any platform specific initialization, and
finally calling start() to load and enter the kernel.
2) It can define platform_init(). In this case the generic crt0.S
handles initial entry, and calls platform_init() before calling
start(). The signature of platform_init() is changed, however, to
take up to 5 parameters (in r3..r7) as they come from the platform's
initial loader, instead of a fixed set of parameters based on OF's
usage.
When using the generic crt0.S, the platform .o can optionally
supply a custom stack to use, using the BSS_STACK() macro. If this
is not supplied, the crt0.S will assume that the loader has
supplied a usable stack.
In either case, the platform code communicates information to the
generic code (specifically, a PROM pointer for OF systems, and/or an
initrd image address supplied by the bootloader) via a global
structure "loader_info".
In addition the wrapper script is rearranged to ensure that the
platform .o is always linked first. This means that platforms where
the zImage entry point is at a fixed address or offset, rather than
being encoded in the binary header can be supported using option (1).

- The address of the initrd image is now added as device tree

- We only copy a packaged initrd image to a new location if it

location, instead of always.
- By default we decompress the kernel directly to address 0,
instead of requiring it to relocate itself. Platforms (such as OF)
where doing this could clobber still-live firmware data structures can
override the vmlinux_alloc hook to provide an alternate place to
decompress the kernel.

[POWERPC] zImage: Add more flexible gunzip convenience functions
At present, arch/powerpc/boot/main.c includes a gunzip() function
which is a convenient wrapper around zlib. However, it doesn't
conveniently allow decompressing part of an image to one location,

This patch adds a new set of more flexible convenience wrappers around
zlib, moving them to their own file, gunzip_util.c, in the process.
These wrappers allow decompressing sections of the compressed image to
different locations. In addition, they transparently handle
uncompressed data, avoiding special case code to handle uncompressed
vmlinux images.
The patch also converts main.c to use the new wrappers, using the new
flexibility to avoid decompressing the vmlinux's ELF header twice as
we did previously. That in turn means we avoid extending our
allocations for the vmlinux to allow space for the extra copy of the

[POWERPC] Remove interrupt-controller as a property under /chosen
Remove interrupt-controller as a valid property under /chosen in
the documentation. There is a consensus that an
interrupt-controller property does not belong under /chosen.
/chosen is specifically for dynamic properties set at runtime.
