x86: dtb: Add support for PCI devices backed by dtb nodes

2011-02-23T21:27:53+00:00

x86_of_pci_init() does two things:

- it provides a generic irq enable and disable function. enable queries
  the device tree for the interrupt information, calls ->xlate on the
  irq host and updates the pci->irq information for the device.

- it walks through PCI bus(es) in the device tree and adds its children
  (device) nodes to appropriate pci_dev nodes in kernel. So the dtb
  node information is available at probe time of the PCI device.

Adding a PCI bus based on the information in the device tree is
currently not supported. Right now direct access via ioports is used.

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/flattree: Add Kconfig for EARLY_FLATTREE

2010-12-29T23:08:18+00:00

The device tree code is now in two pieces: some which can be used generically
on any platform which selects CONFIG_OF_FLATTREE, and some early which is used
at boot time on only a few architectures.  This patch segregates the early
code so that only those architectures which care about it need compile it.
This also means that some of the requirements in the early code (such as
a cmd_line variable) that most architectures (e.g. X86) don't provide
can be ignored.

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.

of/promtree: make drivers/of/pdt.c no longer sparc-only

2010-10-11T03:53:30+00:00

Clean up pdt.c:
 - make build dependent upon config OF_PROMTREE
 - #ifdef out the sparc-specific stuff
 - create pdt-specific header

proc: unify PROC_DEVICETREE config

2010-07-05T22:46:43+00:00

Microblaze and PPC both use PROC_DEVICETREE, and OLPC will as well.. put
the Kconfig option into fs/ rather than in arch/*/Kconfig.

of: Put all CONFIG_OF dependencies into a Kconfig menu block

2010-07-05T22:14:55+00:00

All of the options in drivers/of/Kconfig depend on CONFIG_OF.  Putting
all of them inside a menu block simplifies the dependency statements.
It also creates a logical group for adding user selectable OF options.

This patch also changes (PPC_OF || MICROBLAZE) statements to (!SPARC)
so that those options are available to other architectures (and in
fact the !SPARC conditions should probably be re-evalutated since the
code is more generic now)

This patch also moves the definition of CONFIG_DTC from arch/* to
drivers/of/Kconfig

of/address: merge of_iomap()

Merge common code between Microblaze and PowerPC.  This patch creates
new of_address.h and address.c files to containing address translation
and mapping routines.  First routine to be moved it of_iomap()
