The MPC85xx MDS board requires some board level tweaks of the PHYs that
either the eTSEC (gianfar) or UCC ethernet controllers are connected to.
Its possible to build the phylib as a module, however this breaks the
board level fix ups because phy_read and phy_write are not available
if we build as a module.
So we unconditionally select PHYLIB to ensure its built into the kernel
if we are building in MPC85xx MDS support. This was determined to be
the easiest soultion even though it prevents the user from removing
PHYLIB support if they decide they don't want it.

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.

The Freescale MPC8555CDS and MPC8548CDS reference hardware has a legacy
8259 interrupt controller pair contained within a VIA VT82C686B Southbridge
on the main carrier board. The processor complex plugs into the carrier
card using a PCI slot which limits the available interrupts to the
INTA-INTD PCI interrupts. The output of the 8259 cascade pair is routed
through a gate array and connected to the PCI INTA interrupt line.
The normal interrupt chaining hook (set_irq_chained_handler) does
not allow sharing of the chained interrupt which prevents the
use of PCI INTA by PCI devices. This patch allows the 8259 cascade
pair to share their interrupt line with PCI devices.
NOTE: The addition of the .end routine for the MPIC is not strictly
necessary for this patch. It's there so this code will run from within
the threaded interrupt context used by the Real Time patch.

It also removes ppc_md.irq_bus_setup which was only used by pSeries

Cut-and-paste from the old platform code in arch/ppc resulted in
arch/powerpc/platforms/85xx/mpc85xx_ads.c having way too many
header files included. Clean this up.

This fixes up a variety of minor problems in compiling with ARCH=ppc
arising from using the merged versions of various header files.
A lot of the changes are just adding #include <asm/machdep.h> to
files that use ppc_md or smp_ops_t.
This also arranges for us to use semaphore.c, vecemu.c, vector.S and
fpu.S from arch/powerpc/kernel when compiling with ARCH=ppc.

This creates the directory structure under arch/powerpc and a bunch
of Kconfig files. It does a first-cut merge of arch/powerpc/mm,
arch/powerpc/lib and arch/powerpc/platforms/powermac. This is enough
to build a 32-bit powermac kernel with ARCH=powerpc.
For now we are getting some unmerged files from arch/ppc/kernel and
arch/ppc/syslib, or arch/ppc64/kernel. This makes some minor changes
to files in those directories and files outside arch/powerpc.
The boot directory is still not merged. That's going to be interesting.
