a850a75544 of/address: add empty static inlines for !CONFIG_OF
As the title says, this patch adds empty implementations for the address
translation functions so that they can be used when CONFIG_OF is disabled.

99ce39e359 dt: include linux/errno.h in linux/of_address.h
of_address.h makes reference to some of the error code #defines, so it
needs to include errno.h.  If CONFIG_PCI is not selected, then some files
will fail to compile.

node for a device at a specific address.

0131d8973c of/address: use proper endianess in get_flags
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.

22ae782f86 of/address: Clean up function declarations
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.

dbbdee9473 of/address: Merge all of the bus translation code
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.

1f5bef30cf of/address: merge of_address_to_resource()
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().

6b884a8d50 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()
