The Freescale and Marvell PCI controllers dont require explicit setting for
type 1 config cycles.  They handle producing them by implicitly looking at the
bus, devfn.

The TSI108 and 52xx don't use the generic PCI indirect code and thus don't
bother with set_cfg_type.

The TSI108 code and the 32 bit powermac and chrp platforms
have dependency on PCI that is not easy or desirable to get rid
of.

The easiest fix is to always select CONFIG_PCI if one of those
platforms is enabled.

When CONFIG_PCI is disabled, the definitions for isa_io_base,
isa_mem_base and pci_dram_offset are entirely unused, but they
can result in link failure because they are defined in multiple
places.

The easiest fix is to just remove all these definitions.

Many platforms currently define their own add_bridge function, some
of them globally. This breaks some multiplatform configurations.
Prefixing each of these functions with the platform name avoids
this problem.
Signed-off-by: NArnd Bergmann <arnd@arndb.de>

The cores used in the MPC82xx/83xx/86xx embedded controllers are very similar
to those in the 32 bit general-purpose processors, so it makes sense to
treat them as the same CPU family.

Choosing between the embedded platforms and the multiplatform code is
now done in the platform menu, but functionally everything stays the
same.

A strict reading of the flattened device tree format defined in
booting-without-of.txt does in fact require that all the tags defining
properties for a node go before any definitions of subnodes, however
it's not particularly emphasised.  Although allowing intermingled
properties and subnodes would not be ambiguous in meaning, the kernel
parser does currently require that properties precede subnodes.
Furthermore, keeping this constraint makes life easier for various
device tree scanning tools.

Therefore, re-emphasise in booting-without-of.txt that this is a
strict requirement of the flattened device tree format.

Commit 2e601613 split up
arch/powerpc/boot/of.c so that some OF functions can be used on
platforms that don't want to use the overall OF platform boot code.
This is useful on things like PReP which can have an OF implementation
which is useful for debugging output, but inadequate for booting.

However, that commit didn't export quite enough things to make a
usable OF console on a non-OF system.  In particular, the device tree
manipulation performed to initialize the OF console code must
explicitly use the OF device tree, rather than the flattened device
tree, even if the system is otherwise booting using a flattened device
tree.  This makes it so.

Currently iSeries will recalibrate the cputime_factors in the first
settimeofday() call.

It seems the reason for doing this is to ensure a resaonable time delta after
time_init().  On current kernels (with udev), this call is made 40-60 seconds
into the boot process, by moving it to a late initcall it is called
approximately 5 seconds after time_init() is called.  This is sufficient to
recalibrate the timebase.
