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/address: use proper endianess in get_flags

2010-12-23T22:57:48+00:00

This patch changes u32 to __be32 for all "ranges", "prop" and "addr" and
such. Those variables are pointing to the device tree which contains
integers in big endian format.

Most functions are doing it right because of_read_number() is doing the
right thing for them. of_bus_isa_get_flags(), of_bus_pci_get_flags() and
of_bus_isa_map() were accessing the data directly and were doing it wrong.

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/address: Clean up function declarations

2010-08-01T07:42:42+00:00

This patch moves the declaration of of_get_address(), of_get_pci_address(),
and of_pci_address_to_resource() out of arch code and into the common
linux/of_address header file.

This patch also fixes some of the asm/prom.h ordering issues.  It still
includes some header files that it ideally shouldn't be, but at least the
ordering is consistent now so that of_* overrides work.

of: Provide default of_node_to_nid() implementation.

2010-07-30T06:03:58+00:00

of_node_to_nid() is only relevant in a few architectures.  Don't force
everyone to implement it anyway.

of: remove asm/of_platform.h

2010-07-24T15:57:52+00:00

Only thing left in it is of_instantiate_rtc() which can be moved to
asm/prom.h on PowerPC and is unused in microblaze.

of/address: Merge all of the bus translation code

2010-07-05T22:14:26+00:00

Microblaze and PowerPC share a large chunk of code for translating
OF device tree data into usable addresses.  Differences between the two
consist of cosmetic differences, and the addition of dma-ranges support
code to powerpc but not microblaze.  This patch moves the powerpc
version into common code and applies many of the cosmetic (non-functional)
changes from the microblaze version.

of/address: merge of_address_to_resource()

2010-07-05T22:14:26+00:00

Merge common code between PowerPC and Microblaze.  This patch also
moves the prototype of pci_address_to_pio() out of pci-bridge.h and
into prom.h because the only user of pci_address_to_pio() is
of_address_to_resource().

of/address: merge of_iomap()

2010-07-05T22:14:26+00:00

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()

of/irq: merge irq mapping code

2010-07-05T22:14:25+00:00

Merge common irq mapping code between PowerPC and Microblaze.

This patch merges of_irq_find_parent(), of_irq_map_raw() and
of_irq_map_one().  The functions are dependent on one another, so all
three are merged in a single patch.  Other than cosmetic difference
(ie. DBG() vs. pr_debug()), the implementations are identical.

of_irq_to_resource() is also merged, but in this case the
implementations are different.  This patch drops the microblaze version
and uses the powerpc implementation unchanged.  The microblaze version
essentially open-coded irq_of_parse_and_map() which it does not need
to do.  Therefore the powerpc version is safe to adopt.
