[POWERPC] QEIC: Implement pluggable handlers, fix MPIC cascading
set_irq_chained_handler overwrites MPIC's handle_irq function
(handle_fasteoi_irq) thus MPIC never gets eoi event from the
cascaded IRQ. This situation hangs MPIC on MPC8568E.
To solve this problem efficiently, QEIC needs pluggable handlers,
specific to the underlaying interrupt controller.
Patch extends qe_ic_init() function to accept low and high interrupt
handlers. To avoid #ifdefs, stack of interrupt handlers specified in
the header file and functions are marked 'static inline', thus
handlers are compiled-in only if actually used (in the board file).
Another option would be to lookup for parent controller and
automatically detect handlers (will waste text size because of
never used handlers, so this option abolished).
qe_ic_init() also changed in regard to support multiplexed high/low
lines as found in MPC8568E-MDS, plus qe_ic_cascade_muxed_mpic()
handler implemented appropriately.

[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.

under the root, and that the description of which chip select a given device

cuboot-pq2 is updated to match the binding; previously, it called itself

[POWERPC] 4xx: 440EPx/GRx incorrect write to DDR SDRAM errata workaround
Add a workaround for PowerPC 440EPx/GRx incorrect write to
DDR SDRAM errata. Data can be written to wrong address
in SDRAM when write pipelining enabled on plb0. We disable
it in the cpu_setup for these processors at early init.

[POWERPC] 4xx: Move 440EP(x) FPU setup from head_44x to cpu_setup_4xx
The PowerPC 440EP(x) FPU init is currently done in head_44x
under ifdefs. Since we should support more then one board
in the same kernel, we move FPU initialization code from head_44x
to cpu_setup_44x and add cpu_setup callbacks for 440EP(x).

This adds cpu_setup functionality for ppc44x platform.
Low level cpu-spefic initialization routines should be

added to cputable. The cpu_setup is invoked
by identify_cpu() function at early init.
