Fix constness of the fdt void pointer in fdt_getprop_u32_default

2011-11-13T16:21:34+00:00

The function fdt_getprop_u32_default doesn't modify the fdt, so it can use a
const void * for its fdt argument.

fdt: Add new fdt_set_node_status & fdt_set_status_by_alias helpers

2011-10-18T05:36:55+00:00

Add common function fdt_set_node_status() to assist in various locations
that we set a nodes status.  This function utilizes the status values
that are part of the EPAPR spec (on power.org).

fdt_set_status_by_alias() is based on fdt_set_node_status() but uses an
alias string to identify the node to update.

We also add some shortcut functions to help the common cases of setting
"okay" and "disabled":

	fdt_status_okay()
	fdt_status_disabled()
	fdt_status_okay_by_alias()
	fdt_status_disabled_by_alias()

Finally, we fixup the corenet_ds ethernet code which previously had
a function by the same name that can be replaced with the new helpers.

fdt: check for fdt errors in fdt_create_phandle

2011-10-15T13:35:00+00:00

fdt_create_phandle() was ignoring errors from fdt_set_phandle().  If an
error occurs, print an error message and return 0, which is an invalid
phandle.  We also need to change the return type for fdt_create_phandle()
to indicate that it cannot return an error code.

fdt: Add a do_fixup_by_path_string() function

2011-10-15T13:34:49+00:00

The do_fixup_by_path_string() will set the specified node's property to the
value contained in "status". It would just be an inline wrapper for
do_fixup_by_path() that calls strlen on the argument.

fdt: Add new fdt_create_phandle helper

2011-09-30T00:01:05+00:00

Add a helper function that will return a phandle value for the given
node.  If the node doesn't have a phandle already one will be created.

fdt: Rename fdt_create_phandle to fdt_set_phandle

2011-09-30T00:01:05+00:00

The old fdt_create_phandle didn't actually create a phandle it just
set one.  We'll introduce a new helper that actually does creation.

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()

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.
