libfdt: Add overlay application function

2016-08-20T15:35:04+00:00

The device tree overlays are a good way to deal with user-modifyable
boards or boards with some kind of an expansion mechanism where we can
easily plug new board in (like the BBB, the Raspberry Pi or the CHIP).

Add a new function to merge overlays with a base device tree.

libfdt: Add fdt_setprop_inplace_namelen_partial

2016-08-20T15:35:04+00:00

Add a function to modify inplace only a portion of a property..

This is especially useful when the property is an array of values, and you
want to update one of them without changing the DT size.

libfdt: Add fdt_getprop_namelen_w

2016-08-20T15:35:03+00:00

Add a function to retrieve a writeable property only by the first
characters of its name.

libfdt: Add fdt_path_offset_namelen

2016-08-20T15:35:02+00:00

Add a namelen variant of fdt_path_offset to retrieve the node offset using
only a fixed number of characters.

libfdt: Add max phandle retrieval function

2016-08-20T15:35:01+00:00

Add a function to retrieve the highest phandle in a given device tree.

libfdt: Add iterator over properties

2016-08-20T15:35:00+00:00

Implement a macro based on fdt_first_property_offset and
fdt_next_property_offset that provides a convenience to iterate over all
the properties of a given node.

libfdt: Add a function to write a property placeholder

2016-03-14T18:19:11+00:00

The existing function to add a new property to a tree being built requires
that the entire contents of the new property be passed in. For some
applications it is more convenient to be able to add the property contents
later, perhaps by reading from a file. This avoids double-buffering of the
contents.

Add a new function to support this and adust the existing fdt_property() to
use it.

fdt: Add fdt_first/next_region() functions

2015-07-21T23:39:20+00:00

These have been sent upstream but not accepted to libfdt. For now, bring
these into U-Boot to enable fdtgrep to operate. We will use fdtgrep to
cut device tree files down for SPL.

fdt: Add a function to remove unused strings from a device tree

2015-07-21T23:39:20+00:00

Property names are stored in a string table. When a node property is
removed, the string table is not updated since other nodes may have a
property with the same name.

Thus it is possible for the string table to build up a number of unused
strings. Add a function to remove these. This works by building a new device
tree from the old one, adding strings one by one as needed.

libfdt: fix description of fdt_get_string()

Looks like this comment was copied from that of
fdt_get_string_index().
