58ec4866ed mpc8[56]xx: Put localbus clock in device tree
Export the localbus frequency in the device tree, the same way the CPU, TB,
CCB, and various other frequencies are exported in their respective device
tree nodes.

Some localbus devices need this information to be programed correctly, so
it makes sense to export it along with the other frequencies.

Unfortunately, when someone wrote the localbus dts bindings, they didn't
bother to define what the "compatible" property should be.  So it seems no
one was quite sure what to put in their dts files.

Based on current existing dts files in the kernel source, I've used
"fsl,pq3-localbus" and "fsl,elbc" for MPC85xx, which are used by almost all
of the 85xx devices, and are looked for by the Linux code.  The eLBC is
apparently not entirely backward compatible with the pq3 LBC and so eLBC
equipped platforms like 8572 won't use pq3-localbus.

For MPC86xx, I've used "fsl,elbc" which is used by some of the 86xx systems
and is also looked for by the Linux code.  On MPC8641, I've also used
"fsl,mpc8641-localbus" as it is also commonly used in dts files, some of
which don't use "fsl,elbc" or any other acceptable name to match on.

1266df8877 powerpc: change 86xx SMP boot method
We put the bootpg for the secondary cpus into memory and use
BPTR to get to it.  This is a step towards converting to the
ePAPR boot methodology.  Also, the code is written to
deal properly with more than 4GB of RAM.

ba37aa0328 fdt: rework fdt_fixup_ethernet() to use env instead of bd_t
Move to using the environment variables 'ethaddr', 'eth1addr', etc..
instead of bd->bi_enetaddr, bi_enet1addr, etc.

This makes the code a bit more flexible to the number of ethernet
interfaces.

71074abbe0 8xxx-fdt: set ns16550 clock from CFG_NS16550_CLK, not bi_busfreq
Some boards that have external 16550 UARTs don't have a direct
tie between bi_busfreq and the clock used for the UARTs.  Boards
that do have such a tie should set CFG_NS16550_CLK to be
get_bus_freq(0) -- which most of them do already.

13f5433f70 86xx: Convert sbc8641d to use libfdt.
This is the proper fix for a missing closing brace in the function
ft_cpu_setup() noticed by joe.hamman <at> embeddedspecialties.com.
The ft_cpu_setup() function in mpc8641hpcn.c should have been
removed earlier as it was under the obsolete CONFIG_OF_FLAT_TREE,
but was missed.  Only, the sbc8641d was nominally still using it.
It all got ripped out, and the funcality that was in ft_board_setup()
was refactored to remove the CPU portions into the new file
cpu/mpc86xx/fdt.c instead.  Make sbc8641d use this now.

Based loosely on an original patch from joe.hamman@embeddedspecialties.com
