bff713b562 ibm_newemac: Cleanup/fix support for STACR register variants
There are a few variants of the STACR register that affect more than
just the "AXON" version of EMAC. Replace the current test of various
chip models with tests for generic properties in the device-tree.

aeb4552fad [POWERPC] bootwrapper: Revert ps3 binary flag usage, and remove .bin suffix
The ps3 target produces two images, and the binary one is not the
"primary" image that corresponds to the -o flag; thus, it no longer
uses the generic binary flag.

On platforms which do use the binary flag, it no longer produces a
.bin suffix, so that the output file matches what was passed to the -o flag.

This should fix the zImage ln problems for the ps3 target.

15f8c604a7 [POWERPC] cpm: Describe multi-user ram in its own device node.
The way the current CPM binding describes available multi-user (a.k.a.
dual-ported) RAM doesn't work well when there are multiple free regions,
and it doesn't work at all if the region doesn't begin at the start of
the muram area (as the hardware needs to be programmed with offsets into
this area).  The latter situation can happen with SMC UARTs on CPM2, as its
parameter RAM is relocatable, u-boot puts it at zero, and the kernel doesn't
support moving it.

It is now described with a muram node, similar to QE.  The current CPM
binding is sufficiently recent (i.e. never appeared in an official release)
that compatibility with existing device trees is not an issue.

The code supporting the new binding is shared between cpm1 and cpm2, rather
than remain separated.  QE should be able to use this code as well, once
minor fixes are made to its device trees.

96fca1dea8 [POWERPC] Document local bus nodes in the device tree, and update cuboot-pq2.
The localbus node is used to describe devices that are connected via a chip
select or similar mechanism.  The advantages over placing the devices under
the root node are that it can be probed without probing other random things
under the root, and that the description of which chip select a given device
uses can be used to set up mappings if the firmware failed to do so in a
useful manner.

cuboot-pq2 is updated to match the binding; previously, it called itself
chipselect rather than localbus, and used phandle linkage between the
actual bus node and the control node (the current agreement is to simply use
the fully-qualified address of the control registers, and ignore the overlap
with the IMMR node).

pq2_get_clocks() does the same as the above for the PowerQUICC II,

The mpc8xx/pq2 set_clocks() functions modify common properties in
