efcc2da3fd powerpc/of-device-tree: Factor MTD physmap bindings out of booting-without-of
It's easier to find bindings descriptions in separate files.  So factor
out the MTD physmap bindings into a separate file to not clutter

ec5d7657f7 powerpc: Repair device bindings documentation
Commit d0fc2eaaf4 "powerpc/fsl: Refactor
device bindings" split out a number of device bindings from
booting-without-of.txt into separate files.  Having them all in one file
was a frequent source of merge conflicts.

However, in the next merge, 49997d7515, there
was another conflict.  Some of the bindings removed from
booting-without-of.txt were mistakenly added back in and the copies in
dts-bindings were kept as well.

This patch re-removes "Freescale Display Interface" and "Freescale on board
FPGA" and fixes the table of contents.

83ff9dcf37 powerpc/sysdev: implement FSL GTM support
GTM stands for General-purpose Timers Module and able to generate
timer{1,2,3,4} interrupts. These timers are used by the drivers that
need time precise interrupts (like for USB transactions scheduling for
the Freescale USB Host controller as found in some QE and CPM chips),
or these timers could be used as wakeup events from the CPU deep-sleep
mode.

Things unimplemented:
1. Cascaded (32 bit) timers (1-2, 3-4).
   This is straightforward to implement when needed, two timers should
   be marked as "requested" and configured as appropriate.
2. Super-cascaded (64 bit) timers (1-2-3-4).
   This is also straightforward to implement when needed, all timers
   should be marked as "requested" and configured as appropriate.

9b53a9e28a fbdev: powerpc: driver for Freescale 8610 and 5121 DIU
The following features are supported:
plane 0 works as a regular frame buffer, can be accessed by /dev/fb0
plane 1 has two AOIs (area of interest), can be accessed by /dev/fb1 and /dev/fb2
plane 2 has two AOIs, can be accessed by /dev/fb3 and /dev/fb4
Special ioctls support AOIs

All /dev/fb* can be used as regular frame buffer devices, except hardware
change can only be made through /dev/fb0.  Changing pixel clock has no effect
on other fbs.

Limitation of usage of AOIs:
AOIs on the same plane can not be horizonally overlapped
AOIs have horizonal order, i.e. AOI0 should be always on top of AOI1
AOIs can not beyond phisical display area. Application should check AOI geometry
before changing physical resolution on /dev/fb0

required command line parameters to preallocate memory for frame buffer diufb.

optional command line parameters to set modes and monitor
video=fslfb:[resolution][,bpp][,monitor]
Syntax:

Resolution
xres x yres-bpp@refresh_rate, the -bpp and @refresh_rate are optional
eg, 1024x768, 1280x1024, 1280x1024-32, 1280x1024@60, 1280x1024-32@60, 1280x480-32@60

Bpp
bpp=32, bpp=24, or bpp=16

Monitor
monitor=0, monitor=1, monitor=2
0 is DVI
1 is Single link LVDS
2 is Double link LVDS

Note: switching monitor is a board feather, not DIU feather. MPC8610HPCD has three
monitor ports to swtich to. MPC5121ADS doesn't have additional monitor port. So switching
monirot port for MPC5121ADS has no effect.

If compiled as a module, it takes pamameters mode, bpp, monitor with the same syntax above.

ecc6cd73b7 [POWERPC] Start removing linux,network-index in favour of aliases
This patch alters the bootwrapper for a number of machines (roubhly
all 4xx based cuboot or treeboot platforms) to use aliases instead of
the linux,network-index hack to work out which MAC address to attach
to which ethernet device node.

The now obsolete linux,network-index properties are removed from the
corresponding device trees.  This won't break backwards compatiblity,
because in cases where this fixup code is relevant, the device tree is
part of the kernel image.

The references to linux,network-index are removed from
booting-without-of.txt.  Not only is it now deprecated, but as a hack
applicable only when the device tree blob and fixup code were in the
same image, this property never belonged in booting-without-of.txt
which describes the interface between the kernel and firmware or
bootloaders which produce a device tree.  By the time the device tree
reaches the kernel, all the MAC addresses must be fully filled in.

ab99eee8ac [POWERPC] Xilinx: Update booting-without-of.
This now better describes what the UBoot device tree generator
actually does.  In particular:

1) Nodes have a label derived from the device name, and a node name
derived from a generic version of the device type, e.g. 'ethernet',
'serial', etc.

2) Usage of compound nodes (representing more than one device in the
same IP) which actually works.  This requires having a valid
compatible node, and all the other things that a bus normally has.
I've chosen 'xlnx,compound' as the bus name to describe these compound
nodes.

In addition, I've clarified some of the language relating to how mhs
nodes should be represent in the device tree.

20474abda6 [POWERPC] Fix cache line vs. block size confusion
We had an historical confusion in the kernel between cache line
and cache block size. The former is an implementation detail of
the L1 cache which can be useful for performance optimisations,
the later is the actual size on which the cache control
instructions operate, which can be different.

For some reason, we had a weird hack reading the right property
on powermac and the wrong one on any other 64 bits (32 bits is
unaffected as it only uses the cputable for cache block size
infos at this stage).

This fixes the booting-without-of.txt documentation to mention
the right properties, and fixes the 64 bits initialization code
to look for the block size first, with a fallback to the line
size if the property is missing.

1d3bb99648 Device tree aware EMAC driver
Based on BenH's earlier work, this is a new version of the EMAC driver
for the built-in ethernet found on PowerPC 4xx embedded CPUs.  The
same ASIC is also found in the Axon bridge chip.  This new version is
designed to work in the arch/powerpc tree, using the device tree to
probe the device, rather than the old and ugly arch/ppc OCP layer.

This driver is designed to sit alongside the old driver (that lies in
drivers/net/ibm_emac and this one in drivers/net/ibm_newemac).  The
old driver is left in place to support arch/ppc until arch/ppc itself
reaches its final demise (not too long now, with luck).

This driver still has a number of things that could do with cleaning
up, but I think they can be fixed up after merging.  Specifically:
	- Should be adjusted to properly use the dma mapping API.
Axon needs this.
	- Probe logic needs reworking, in conjuction with the general
probing code for of_platform devices.  The dependencies here between
EMAC, MAL, ZMII etc. make this complicated.  At present, it usually
works, because we initialize and register the sub-drivers before the
EMAC driver itself, and (being in driver code) runs after the devices
themselves have been instantiated from the device tree.

f023dc769c [POWERPC] spi: mode should be "cpu-qe" instead of "qe"
Mode should be "cpu-qe" for QE in CPU mode. "qe" should be reserved
for native QE mode.
