fdt: introduce fdt_create_phandle()

2011-07-15T01:43:45+00:00

The ePAPR specification says that phandle properties should be called
"phandle", and not "linux,phandle".  To facilitate the migration from
"linux,phandle" to "phandle", introduce function fdt_create_phandle(),
which creates a phandle in a given node.  For now, we create both the
"phandle" and "linux,phandle" properties.  A later version of this
function will remove support for "linux,phandle".

fdt: add prototype for fdt_increase_size()

Add a prototype for fdt_increase_size() so that anyone can call it.

fdt: introduce fdt_verify_alias_address() and fdt_get_base_address()

2011-07-15T01:43:36+00:00

Introduce two functions, fdt_verify_alias_address() and
fdt_get_base_address(), which can be used to verify the physical address
of a device in a device tree.

fdt_get_base_address() returns the base address of an SOC or PCI node.

fdt_verify_alias_address() prints a message if the address of a node
specified by an alias does not match the given physical address.

FDT: Add fixup support for multiple banks of memory

2010-10-18T20:50:53+00:00

Add fdt_fixup_memory_banks and reimplement fdt_fixup_memory
using it.  Tested on OMAP3 beagle board with two banks of
memory.

fdt_support: support adding EDID property to FDT display nodes

2010-10-12T19:05:58+00:00

Boards can pass display timing info for drivers using EDID
block. Provide common function to add board specific EDID
data to the device tree. Subsequent patch makes use of this
functionality.

Detailed timing descriptor data from EDID is used for
programming the display controller. This is currently
implemented on the Linux side by the fsl-diu-fb frame
buffer driver and it is documented there in
Documentation/powerpc/dts-bindings/fsl/diu.txt.

ppc4xx/fdt/flash: Change fdt_fixup_nor_flash_node() to not rely on cs size

2010-09-23T06:49:49+00:00

This patch changes the behaviour of the fdt_fixup_nor_flash_node()
function. Now it doesn't patch the size of the "reg" property with the
chip-select size, but with the size returned from the new function
flash_get_bank_size(). This function will return per weak default the
flash size of the bank (bank = chip-select numer) detected by the flash
driver. If this does not fit your needs, this function may be overridden
by a board specific one.

For this the parameters needed to be changed. So I intentionally squashed
the PPC4xx stuff using this routine into this patch. Otherwise it would
not be git-bisectable anymore.

The board specific function for the AMCC/APM Ebony eval board is now
included in this patch version.

fdt: Add function to alloc phandle values

2010-07-26T18:07:56+00:00

If we are creating reference (handles) to nodes in a device tree we need
to first create a new phandle in node and this needs a new phandle
value.  So we search through the whole dtb to find the max phandle value
and return the next greater value for a new phandle allocation.

fdt: Add fdt_node_offset_by_compat_reg helper

2010-07-20T09:40:06+00:00

Given a compatible string and physical address try and find a node that
matches.  This is useful when we want to find a specific device node to
update (for example if we have multiple PCI nodes we can use the
physical address to distinguish them when trying to update the device
tree).

fdt: Add fdt_translate_address to convert reg node to cpu phys addr

2010-07-20T09:40:00+00:00

This code is extracted out of the Linux Kernel code from
arch/powerpc/kernel/prom_parse.c.

We maintain some of the same structure to support multiple bus types even
though we only have one in the current code.  In the future we might want
to translate across a PCI bus and thus it will be easier to add that
functionality back in.

powerpc/8xxx: Distinguish between incompatible SEC h/w types

2010-07-16T15:55:07+00:00

CONFIG_SYS_FSL_SEC_COMPAT is set to 2 for the SEC 2.x and SEC 3.x.
Parts with newer SEC h/w versions will increment the number to
accomodate incompatible code changes.
