Robert Brose a78bfbfcfa [POWERPC] Add kernel parameter to set l3cr for MPC745x
Old-world powermacs don't set L2CR or L3CR on processor upgrade cards.
This simple patch allows the setting of L3CR via a kernel parameter
(like the existing kernel parameter to set L2CR).

Geert Uytterhoeven b163a256da [POWERPC] PS3: Split device setup for static vs. dynamic devices
Split the device setup code in ps3_register_repository_device() in two
routines:
  1. ps3_setup_static_device(), to handle the setup of static devices in the
     PS3 repository, which can be __init,
  2. ps3_setup_dynamic_device(), to handle the setup of storage devices that
     may appear later in the PS3 repository.

This fixes a few section mismatch warnings.

It appears that in some cases, the sync word might not be recognized

from the port results in an unrecoverable error because of the design
of the FPGA core.  This patch updates the code to check the status of
the device before reading the IDCODE, in order to avoid entering this
unrecoverable state.  This patch also adds additional NOOP commands
into the sychronization sequence, which appears to be necessary to
avoid the condition on some hardware.

David Gibson ecc6cd73b7 [POWERPC] Start removing linux,network-index in favour of aliases
This patch alters the bootwrapper for a number of machines (roubhly
all 4xx based cuboot or treeboot platforms) to use aliases instead of
the linux,network-index hack to work out which MAC address to attach
to which ethernet device node.

The now obsolete linux,network-index properties are removed from the
corresponding device trees.  This won't break backwards compatiblity,
because in cases where this fixup code is relevant, the device tree is
part of the kernel image.

The references to linux,network-index are removed from
booting-without-of.txt.  Not only is it now deprecated, but as a hack
applicable only when the device tree blob and fixup code were in the
same image, this property never belonged in booting-without-of.txt
which describes the interface between the kernel and firmware or
bootloaders which produce a device tree.  By the time the device tree
reaches the kernel, all the MAC addresses must be fully filled in.

S.Çağlar Onur 59861bc6ee [POWERPC] arch/powerpc/platforms/iseries/pci.c: Use time_* macros
The functions time_before, time_before_eq, time_after, and
time_after_eq are more robust for comparing jiffies against other
values.

This implements usage of the time_after() macro, defined at
linux/jiffies.h, which deals with wrapping correctly.
