of: remove HAVE_ARCH_DEVTREE_FIXUPS

2013-10-10T01:04:08+00:00

HAVE_ARCH_DEVTREE_FIXUPS appears to always be needed except for sparc,
but it is only used for /proc/device-teee and sparc does not enable
/proc/device-tree. So this option is redundant. Remove the option and
always enable it. This has the side effect of fixing /proc/device-tree
on arches such as arm64 which failed to define this option.

of: implement pci_address_to_pio as weak function

2013-10-10T01:04:06+00:00

Implement pci_address_to_pio as weak function to remove the dependency on
asm/prom.h. This is in preparation to make prom.h optional.

microblaze: clean-up prom.h implicit includes

2013-10-10T01:04:03+00:00

While powerpc is a mess of implicit includes by prom.h, microblaze just
copied this and is easily fixed. Add the necessary explicit includes and
remove unnecessary includes and other parts from prom.h

microblaze: remove undefined of_get_cpu_node declaration

2013-08-21T09:23:30+00:00

This patch removes the declaration of the function 'of_get_cpu_node'
which is not defined for microblaze. This is in preparation to move
it's definition from PPC to DT common code.

Michal Simek says: "it was just there because Microblaze
was based on powerpc code"

microblaze: Simplify early console binding from DT

2011-07-25T07:25:13+00:00

Recognize early Linux console from chosen - linux,stdout-path

compatible strings.
This patch solved the problem on system with multiple
consoles.

pci/of: Match PCI devices to OF nodes dynamically

2011-06-07T23:08:17+00:00

powerpc has two different ways of matching PCI devices to their
corresponding OF node (if any) for historical reasons. The ppc64 one
does a scan looking for matching bus/dev/fn, while the ppc32 one does a
scan looking only for matching dev/fn on each level in order to be
agnostic to busses being renumbered (which Linux does on some
platforms).

This removes both and instead moves the matching code to the PCI core
itself. It's the most logical place to do it: when a pci_dev is created,
we know the parent and thus can do a single level scan for the matching
device_node (if any).

The benefit is that all archs now get the matching for free. There's one
hook the arch might want to provide to match a PHB bus to its device
node. A default weak implementation is provided that looks for the
parent device device node, but it's not entirely reliable on powerpc for
various reasons so powerpc provides its own.

of/pci: move of_irq_map_pci() into generic code

2011-02-04T18:46:50+00:00

There is a tiny difference between PPC32 and PPC64. Microblaze uses the
PPC32 variant.

of/net: Move of_get_mac_address() to a common source file.

2010-11-01T05:08:14+00:00

There are two identical implementations of of_get_mac_address(), one
each in arch/powerpc/kernel/prom_parse.c and
arch/microblaze/kernel/prom_parse.c.  Move this function to a new
common file of_net.{c,h} and adjust all the callers to include the new
header.
